Document Summary
September 20th lecture biology and behaviour (part. Each cell in the human body has 46 chromosomes (23 pairs 1 from each parent of those pairs) Chromosomes are filled with dna (genetic blueprint) That dna is composed of four nucleotide bases. All of our genetic material is encompassed in sequences of those bases. It is through the process of dna replication during mitosis that we understand why every cell in an organism contains the same genetic material. Specific segment of dna: responsible for the production of a specific protein, some characteristics, not many, are associated with the presence or absence of a single gene (cystic fibrosis, In most cases it"s much more complicated than just one gene: human genome project developed to determine the sequence of 3 billion nucleotide pairs on the 46 chromosomes. The project is finished but we don"t know all the answers yet: 21,000 genes in the human body, before the human genome project, there were estimates of.
