Answer:

D. none of the above

Explanation:

The egg itself is not a cell, but its egg yolk is considered a macrocell (which can be seen with the naked eye). This macrocell is nothing more than an oocyte II when there is no fertilization, or an embryo where no fertilization has occurred.

Regardless of fertilization, the egg forms in domestic chickens, roughly, as occurs in women monthly ovulation (menstruation). Thus, if the breeder's goal is to produce eggs for consumption, then only unfertilized eggs will be obtained, so the macrocell is formed because there was no fertilization.

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.
