Document Summary
Bio319 genetics study guide for unit 1, lecture 1. Where are genes located: a gene is a specific sequence of dna within a chromosome (long polymer of dna), the sequence of bases creates a gene and distinguishes it from other genes. They are in chromosome within living cells: briefly explain how gene expression occurs at the molecular level, a sequence of dna (gene) is transcribed into rna. Gi(cid:448)e t(cid:449)o e(cid:454)a(cid:373)ples of genetic variation at the molecular level: genetic variation means the genetic differences within the same/different species. Example would be different color among animals depended on chromosome structure and number. Describe the numbering of the carbon atoms in deoxyribose with regard to the directionality of a dna strand. Its nucleotide base sequence: the methyl group (ch3) is not attached to the atoms with hydrogen bond, not directly affect. It could indirectly affect hydrogen bonding if it perturbed the structure of dna.
