ANT E101 Lecture Notes - Lecture 6: Dna Replication, Polynucleotide, Peptide
Document Summary
Capable of coding for diverse information, including proteins. Capable of transmitting this information, to regulate development and normal cell functioning. Resides in the nucleus of the cell. Made up of smaller molecules called nucleotides. Each nucleotide contains 1 of 4 different bases, with one exception. Dna first strand - ata gat cgc tta. Dna second strand (complementary) - tat cta gcg aat. Complementary polynucleotide chains (specificity of base pairing) provides a mechanism by which the molecule can replicate itself. The sequence of nucleotide bases varies, and contains important information (ie the genetic code) Occurs during cell division within the nucleus in the cell. Original polynucleotide strands separate, leaving their bases exposed. Original strands templates for two complementary strands. Results in two identical copies of the dna molecule. Proteins may serve as structural components of body tissues or play active functional roles. Amino acid subunits are linked together to form linear polypeptide chains.
