Why are genes so important in a SES context?
All biological functions are carried out by human proteins. Genes provide information to make proteins required Genes (DNA) -> RNA -> Proteins -> Biological function/physical activity (SES)
What are the proteins in DNA
Adenine + Thymine Guanine + Cytosine
What is a gene
• a segment on the DNA that contains enough information necessary to build a protein • one gene, one polypeptide • one or more polypeptides = protein • genes and proteins control growth, development and function
What is a genotype
• your set of genes; your individual genetic make-up at the molecular level • 23 pairs of chromosomes; about 23,000 genes • gene variations exist, and are generated by mutations/errors in the sequence
What is a phenotype
• observable characteristics or attributes resulting from the expression of MANY genes from over 100,000 different proteins
How does information come from the DNA?
Occurs with transcription - copy of the DNA strand; messenger ribonucleic acid (mRNA), carried out by the enzyme RNA polymerase; ribose sugar instead of deoxyribose and uracil (U) base instead of thymine (T)
