23. DNA = double stranded, deoxyribose, found in nucleus, contains thymine, stores genetic info, nitrogen bases A, T, C, G RNA = single stranded, ribose, found in nucleus and ribosomes, contains uracil, makes proteins, nitrogen bases AUCG - Both are essential in living organisms. 24. transcription = process of copying a sequence of DNA to produce a complementary strand of RNA translation = process that converts an mRNA message into a polypeptide 25. Three nucleotides make up one codon. One codon codes for an amino acid. More than one codon can code for a single amino acid. The sequence of codons in the mRNA determines the sequence of amino acids in the polypeptide chain. 26. Every polypeptide chain is coded for by one gene. For example, if you have the gene for brown eyes, it means that you have the gene that makes brown pigment. 27. enzyme = a globular protein molecule that accelerates a specific chemical reaction active site = region of an enzyme’s surface that binds the substrate (reacting
