BIOL 2040 Lecture Notes - Lecture 1: Okazaki Fragments, Chromosome, Semiconservative Replication
Document Summary
Jan 9 biol2040: karyotype, chromosome, genetic material. What are the characteristics a molecules must exhibit to be considered genetic material: 1. Variation by mutation: review what you know about dna and rna structure with the person next to you. A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups. What are some similarities and difference btw rna and dna. Complementary base pairing is the phenomenon where in dna guanine always hydrogen bonds to cytosine and adenine always binds to thymine. What holds the pairs together? (hydrogen bonds: nucleic acid are composed of nucleotides. In order to carry information, we need multiple letter (bases) Encode the information by ordering these bases. We have 4 options (at, gc) - nucleic acid. Proteins have 20 letters: nucleic acids are composed of nucleotides.
