C. It is made of 11 atoms and 3 elements
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.
The cause of increase in the snake population most likely due to environmental factors, such as, rainfall, temperature, sunlight, and food availability. Good health in female snakes is also a factor which makes snake population increase. Snakes ensure that their offsprings are born during warm season.
