Drosophila Correct Answer-fruit fly Why do we care about Drosophila development? Correct Answer-they are sophisticated genetic and molecular biology tools, and they have revealed many genetic controls underlying development that are conserved in flies and humans Life cycle if Drosophila Correct Answer-fertilization, hatching, pupation, metamorphosis, adult How long after Drosophila fertilization does hatching occur? Correct Answer-1 day How long after Drosophila fertilization does pu...

What is the minimum number of nucleotides per amino acid required to specify all 20 amino acids? Correct Answer-3 nucleotide bases per amino acid Codon Correct Answer-a triplet of nucleotides that codes for a specific amino acid Translation occurs in such a way that these nucleotide triplets are read in a successive, nonoverlapping the key to the translation of genetic information, directing the synthesis of specific proteins Overlapping Correct Answer-AUACGAGUC -> is read like AU...

ligand Correct Answer-a small molecule that binds specifically to a larger one (i.e., protein). For example, a hormone is the ligand for its specific protein receptor [a molecule bound reversibly by a protein. binding site Correct Answer-the location (crevice or pocket) on a receptor protein to which a ligand binds induced fit Correct Answer-The change in shape of the active site of an enzyme so that it binds more snugly to the substrate, induced by entry of the substrate. Renders the subs...
