Which of the following inheritance patterns is matched with an inaccurate molecular basis?
A. Incomplete dominance; The protein produced by a wild-type allele affects the phenotype in a concentration-dependent manner. B. Codominance; Two proteins are produced in heterozygotes. C. Sex-infuenced; Hormones alter the expression of proteins encoded by dominant and recessive alleles. D. X-linked; Hemizygotes with the recessive allele do not make a functional protein, but heterozygotes do. E. Simple Mendelian inheritance; The protein produced by a single allele cannot produce the dominant phenotype.
Why are some proteins synthesized after single-codon mutations still semi-functional?
a. Proteins are transported to the nucleus to be compared to and corrected by the cell’s DNA. b. Degeneracy ensures that all single-codon substitution specify the same amino acids. c. Substituted amino acids may have similar properties as the originally specified amino acids. d. Only the average properties of every amino acid in a protein determine its functionality.
Viruses:
a. Consist of only a single cell b. Are smaller than cells c. Consist of multiple cells d. Contain a nucleus e. Contain ribosomes
