Gene o Segment of DNA located at a particular place on a chromosome o DNA codes for specific A.A. sequence in protein or for the RNA to help make proteins The continuous and discontinuous strands in DNA replication differ in that only on the discontinuous strand is DNA replicated in short fragments . DNA vs. RNA (table 10-1) DNA o Double stranded o Deoxyribose o A-T; C-G o Recipe RNA o Single stranded o Ribose o A-U; C-G o Function based on type (3 types) Three types of RNA (fig. 10-2) mRNA: base sequence of mRNA carries info for AA sequence in protein rRNA: combines w/ proteins to form ribosomes tRNA: carries specific AA to a ribosome Information flow in a cell: DNA is transcribed into RNA; RNA is translated into protein.
