At the molecur level, how do dna sequences relate to an organisms genes?

Genes are regions of chromosomes; a single chromosome can have hundreds or thousands of genes along its length.

Each chromosome is made of DNA (and associated proteins). So each gene is made up of a certain relatively short stretch of DNA along a chromosome.

Each of the DNA nucleotides that make up a gene has one of the four bases (A, C, T, or G) as a component. It is the sequence of the bases that allows a gene to encode information (similar to how the sequence of English letters, or the sequence of 0's and 1's of the binary language computers use, allows them to encode information).

you have a simplified and idealized photograph of ways DNA works. Iy is unlike pistons in an engine shifting a motor vehicle forward. it somewhat is an occasion of reliable engineering, the place all the issues is needed and streamlined to terrific carry out its job. Biochemistry, controlled by making use of DNA is carefully diverse. that's disorganized, chaotic and extremely almost thoroughly unrecognizable on the molecular point. that's basically while great numbers of competing and conflicting reactions are averaged over tens of millions of examples does something like order form of percolate to the exterior. even nevertheless that's order rising from chaos, no longer from the sleek working of a nicely prepared software. and that's the clue that it's not designed yet lashed mutually by making use of trial and mistake. numerous blunders. So the case can extra suited be made that existence progressed many wonderful characteristics reacting to the on a daily basis trials of residing issues in ever changing environments. each little thing, chemically which would be tried, from any given genetic commencing factor, at last would be tried. the enormous numbers of failures are discarded by making use of dying or sterility and the very few wonderful advances are retained and noticeably extra desirable and further experimented upon. This technique has somewhat no resemblance to what's occurring in a tornado or 1000000000 tornadoes. that thought is your guy or woman straw guy, on no account what evolutionary thought is claiming. The Pope accepts the validity of evolutionary thought. that's a shame the e book I correct to, decrease than, is so costly. however the Pope could have the money for it. -- Regards, John Popelish
