When sequencing the genome of an organism and looking for potential genes, a sequence of DNA that would produce an RNA with a many bases between a start and stop codon is known as a promoter an operon an open reading frame a chromsome

Figure 28.41 gives some examples of recombination in IgG codons 95 and 96, as specified by the Vkand Jkgenes. List the codon possibilities and the amino acids encoded if recombination occurred in codon 97. Which of these possibilities is less desirable?

The following segment of DNA codes for a protein. The uppercase letters represent exons. The lowercase letters represent introns. The lower strand is the template strand. Draw the primary transcript and the mRNA resulting from this DNA.

_______ are removed from new mRNAs. a. Introns c. Poly-A tails b. Exons d. Amino acids

A binding site for RNA polymerase is called a ________. a. gene c. codon b. promoter d. protein

Portions of eukaryotic mRNA sequence that are removed during RNA processing are . a. exons b. caps c. poly-A tails d. introns

Which of the following is characteristic of genes and gene regulation in both bacteria and eukaryotes? (a) promoters (b) non-coding DNA within coding sequences (c) enhancers (d) operons (e) DNA located in a nucleus

The genetic code is defined as a series of _______________ in _______________. (a) anticodons; tRNA (b) codons; DNA (c) anticodons; mRNA (d) codons; mRNA (e) codons and anticodons; rRNA

A frameshift mutation is caused by a: a. nucleotide substitution b. three-base insertion c. premature stop codon d. one-base insertion e. two-base deletion

A scientist mutates elF-2 to eliminate its GTP hydrolysis capability. How would this mutated form of elF-2 alter translation? Initiation factors would not be able to bind to mRNA The large ribosomal subunit would not be able to interact with itiRNA transcripts tRNAi-Met would not scan mRNA transcripts for the start codon elF-2 would not be able to interact with the small ribosomal subunit.
