Aparticular protein has the following amino acid sequence within its primary structure (n . . ala-pro-his-trp-arg-lys-gly-val-thr . . c). a geneticist studying mutations affecting this protein discovered that several of the mutants produced shortened protein molecules that terminated within this region. in one of them, the his became the terminal amino acid. what dna single-base change(s) would cause the protein to terminate at the his residue? what other potential sites do you see in the dna sequence encoding this protein where mutation of a single base pair would cause premature termination of translation

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?
