Answer: Gray whales have no dorsal (back) fins. Instead, they have a low hump and a series of six to twelve knuckles or bumps. Gray whales are baleen whales, and each has approximately 300 plates of cream-colored baleen hanging from its upper jaw. Two to five throat creases allow their throats to expand during feeding.

A transcription unit that is 8,000 nucleotides long may use 1,200 nucleotides to make a protein consisting of approximately 400
bearhunter [10]

Answer:

A) many noncoding stretches of nucleotides are present in mRNA.

Explanation:

A transcription unit in eukaryotes includes the region that code for mRNA extending from the 5' cap site to the 3' poly-A site. It also includes the controlling regions. The mRNA formed by transcription also has some non-coding intervening sequences. These are called introns. Introns are removed from the primary transcripts by the process of splicing that occurs after transcription.

Therefore, a transcription unit that is 8,000 nucleotides long may use only 1,200 nucleotides to code for a protein having 400 amino acids since the rest of the nucleotides are part of introns and are removed from mRNA after transcription.
