When comparing DNA polymerase I and DNA polymerase III functions, we find that Group of answer choices both DNA polymerases have exonuclease activity. only DNA polymerase I adds a nucleotide to the 3' end of a polynucleotide. both DNA polymerases add a nucleotide to the 5' end of a polynucleotide. only DNA polymerase III has polymerase activity. both DNA polymerases replace an RNA nucleotide with a DNA nucleotide.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
