Evolution How are genes and proteins related? Genes determine protein structure Protein structure determines the way the processes of life are carried out Gene RNA to make protein o DNA RNA Protein DNA mRNA Ribosomes codons protein Gene: segment of DNA located at a particular place on a chromosome DNA codes for a specific AA sequence in a protein or for the RNA that helps make proteins o Within this sequence there is a code that is not so useful DNA vs RNA (10-1) o DNA is double stranded and made up of deoxyribose o RNA is single stranded and made up of ribose Polymers: nucleic acids o A,T,G,C DNA o A,U,G,C RNA Three types of RNA (10-2) o mRNA o rRNA two subunits protein synthesis takes place here o tRNA o all living things on the planet use this! Information flow (10-3) o Open up DNA for transcription or replication by DNA helicase

o RNA is made by RNA polymerase (-ase is most likely an enzyme, a protein that speeds up a chemical reaction) o Enzyme that is used to copy DNA is called DNA polymerase Transcription o DNA to RNA mRNA in nucleus and make it way to rough ER and at the ribosome’s translation will take place Translation o RNA to proteins Going from nucleotides to amino acids “switching languages” o AUG is start codon tRNA brings in amino acid (met) codon is not found in DNA How is information in a gene transcribed into RNA transcription
