Concept

Problem: 1. Which of the following are present in your liver cells?a. enhancers of genes expressed in the liverb. promoters of genes expressed in the liverc. enhancers of genes expressed in the kidneyd. promoters of genes expressed in the kidneye. All of the above are present in liver cells2. Why are genes for rRNA and tRNA considered to be genes even though they do not produce polypeptides?a. rRNA and tRNA are also gene products along with polypeptides.b. The structures of tRNA and rRNA are similar to the structures of polypeptides.c. The functions of rRNA and tRNA are similar to the functions of polypeptides.d. The statement is false; DNA sequences encoding for rRNA and tRNA are not actually genes.
