acid (DNA) and is located within the nucleus of your cells. chromosome number being halved, so instead of pairs state the relationship between DNA, genes and proteins . (b) Select at least five terms and create a poem or song. Revise genetic inheritance for Edexcel with BBC Bitesize. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and For example, the gene for eye colour has an allele for blue eye colour and an. It should somehow be about “the relation between genes and music, the human genome . Michael felt my poem about alleles, though, had more mileage. . has two copies of each chromosome, two alleles make up the individual's genotype.
With the exception of identical twins, each person's DNA is unique. The order of these letters makes up an organism's genetic code.
An organism's genome is one copy of all of their DNA. With the exception of identical twins, no two people's genomes are the same.
Some characteristics are controlled by a single gene, such as fur in animals and red-green colour blindness in humans. Each gene might have different forms, and these are called alleles. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.
Chromosomes are made from genes which are made from the DNA double helix Chromosomes are found in the nucleus of a body cell in pairs. One chromosome of each pair is inherited from the mother and the other one is inherited from the father. The chromosome in each pair carries the same gene in the same location. These genes could be the same, or different versions: Alleles are different versions of the same gene.
For example, the gene for eye colour has an allele for blue eye colour and an allele for brown eye colour. For any gene, a person may have the same two alleles, known as homozygous or two different ones, known as heterozygous. A dominant allele is always expressed, even if one copy is present.
Dominant alleles are represented by a capital letter, for example you could use a B. Cells, I was beginning to realize, are all about self and other. Allele was the variant, the Other. Each human cell, I learned, has two copies of each gene. They often differ from each other in having a slightly different order of genetic letters.
Each copy is an allele. New ones are created through mutation. Doubleness, alternativeness, was a vital to the whole business of cells. For a composer, the shorter the text the better.
Michael would need something very economical but I sent him the lot in case one struck him he could work with.
Genetics - Biology As Poetry
It could be far more abstracted. Perhaps the issue is that all these poems are so precisely focussed, but not on that thing of tiny differences, that they don't quite give me the 'hold' I think I still need.
Michael felt my poem about alleles, though, had more mileage. For me, it looked as if wanted something more imagistic. He wondered if instead of using a single poem for the whole piece he could use different poems or ideas for different sections of the music. Would I mind if he lifted lines out of different poems?
The words had to open doors for him, give him space to do his own melodic, structural and harmonic imagining. My experience of working with composers was that at some point the text provider has to offer words then back right away. I had my 23 poems, I was happy with them, the process had already been enormously productive for me.
When Michael came round, the first time we met, I could hardly speak. We spread the poems over the kitchen table. A tiger, in my case. Would Michael like something on those lines - a series of images for what the science was about, those tiny differences in a sequence? It was now mid September. I suspect that pairings are going to be important. I added the numbers of syllables in each line in each half, in case that was useful and called it Strangers and Others. I had no idea we were going to go through seven more drafts over two months to arrive at what we were both happy with.
Secret scripture, written on red sky by wheeling birds. Allelic mysteries of cell, all different, all the same. Shadow in the mirror of the self; the Other who reveals the exit wound; the hare still in its form, leaving its imprint behind. A barcode, occult as Kabbalah, invisible as fireflies on a blade of grass in pre-dusk blue of day. The Stranger who should be welcome in your home for the stranger might also be god. I think I have to give some proper thought to the amount of text and not be wasting your time until I really know that.
Could you possibly bear with me till then? As soon as I get something from him, I'll work on it - and be in touch. I'm wondering too, as there will be so much musical repetition, that to tie this in, the poetry repeats patterns of words in one way or another Please don't feel obliged to do now! But if that one starting line came, it would help me I think to get going.
I felt we were getting close at last to what was needed. Michael clearly thought much more mathematically than me but poetry is all about very precise sounds and once you get technical you are into the home straight. But it would be great if each of the units, 1, 1, 2, 3, and 5 could also make sense, be 'complete' enough as units too.
Could you imagine the first line refrain, or perhaps better a fragment of it, coming in the 1, 2, 3 line segments as well as the 5 and 8, perhaps each time a little more, a word more, so slowly growing. These patterns would map excellently into music To point to an allele for musicality.

- Genetic inheritance
He laid out for my layman's mind that an allele is a 'specific form of a gene. An individual's genotype for that gene is the set of alleles it happens to possess. In a diploid organism, one that has two copies of each chromosome, two alleles make up the individual's genotype. An example is the gene for blossom color in many species of flower — a single gene controls the color of the petals, but there may be several different versions or alleles of the gene.
One version might result in red petals, while another might result in white petals.
The resulting color of an individual flower will depend on which two alleles it possesses for the gene and how the two interact. An allele is an alternative form of a gene in diploids, one member of a pair that is located at a specific position on a specific chromosome. Diploid organisms, for example, humans, have paired homologous chromosomes in their somatic cells, and these contain two copies of each gene.
We had something in common - we both it seemed could react to an idea, a chain of responses with the precision and technicalities which science is all about - but so, when you get down to them, are poetry and music. At any rate to return to the main point: So yes, 20 - but with repetitions of the opening line or part, and each section being complete making sense in itself if building up to 20 lines - is that okay?
And I had allowed my obsession with migrating to creep into the images I brought to the table. Flight of the tiniest humming-birds, in sequence. Red and orange wings above the sea in the unknown mystery: Fireflies, invisible, occult as Kabbalah, sleeping in the mysteries of day. Tiniest wings folded over lightning.
Plankton, invisible in the pelagic zone, till they become a mystery of the moon: The mystery of the tiniest differences.
A barcode occult as Kabbalah. Alleles, shadows in the mirror of the self, invisible. Tiniest freckles on a silver sea when dawn scatters autumn cloud. The unknown Other, embedded in the sequence and revealed in song. A stranger who should be welcome in your home, for the Stranger might also be god.
How are DNA, chromosomes, genes, and alleles related?
We were both enmeshed in other lives now, the lives of term, teaching and writing. I was up and down from Cambridge, he was up and down to Southampton. And for redoing and redoing. I love the way you've embedded the Fibonacci in the 5 times 4 line structure. All the repetitions and half repetitions are just right. Hope you feel it stands as a poem in itst own right as well as words for music. Love that you keep the final sentiment from your final poem. Hope to speak later in the week.
I too feel god with small g would be better - what do you think? Michael wanted something much more mathematically patterned to fit in with what he wanted and you wanted, so I did him an extra one of his own, using some of the language and images from the sequence. We are still tinkering with tiny details, but he is happy with this. I've taken the liberty of tweaking a few tiny things. I think you will see this as disturbing your poetic metre, in fact I'm sure you will!
Without it the music can just begin straight in - with it I have to set this word as some kind of upbeat - and I can only say this is something I really would like to avoid as it will at the very start stop up the flow. But if it is singular and personal, I feel it brings the subject closer to a listener and to the singers - they will be able then sing 'to' the allele and not just about it. If it is, it supports still more the singularisation.
But I hope you'll understand why - it will allow the music to flow fully out of your beautiful words, and at no time be blocked by them. I don't know if this is a problem or not Mystery of the tiniest difference.
