Unformatted text preview: Week 5 15.1-15.2- Genes make proteins, they contain the instructions for making protein- DNA paired A-T, G-C- Different combination of bases could specify the 20 amino acids- mRNA carry info from DNA to protein site synthesis- RNA polymerase catalyzes synthesis of RNA- DNA > RNA -> proteins - Genotype is determined by the sequence of bases in its DNA while the phenotype is a product of the proteins it produces- If the primary structure of proteins vary, there function is likely to as well- Alleles of the same gene differ in their DNA sequence. - RNAs help regulate which genes are transcribed at various times, process mRNA prior to translation, transport the amino acids required to build proteins, Catalyze the formation of peptide bonds. - In some cases info flows from RNA to DNA 4.1-4.3- Nucleic acids are polymers that make up nucleotides- Purines: A and G- Pyrimidines: C and U- Phosphodiester bond: formation of a bond between the phosphate group of one nucleuotide and the hydroxyl group of the sugar component of another nucleotide, it is a...
