Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.
Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.
Answer:
a) Yes
b) Yes
c) Yes
d) Yes
Explanation:
a.
In the exons?
Yes mutant site will be expected. It will transcript-ed as well and it can be a polypeptide depending on the mutation type.
b.
In the intron?
Yes mutant site will be expected. It will be transcript-ed as well and it cannot be a polypeptide
c.
In the promoter?
Yes mutant site will be expected. It will not be transcript-ed and it cannot be a polypeptide
d.
In the intron-exon boundary?
Yes mutant site will be expected. It will be transcript-ed and it cannot be a polypeptide
Circulatory system:
--The circulatory system is also known as the cardiovascular system.
-- It is composed of the heart, blood, blood vessels and also includes the lungs.
The primary function of the circulatory system to distribute oxygen, nutrients, hormones and other gases to cells of the other body systems. It delivers all the necessary components needed for all the cell activities. Without the circulatory system, we would not be alive.
It is our blood that carries these necessary nutrients, hormones, and oxygen. All these components trigger certain processes that keep other organs functioning. It also plays a role in eliminating waste by carrying them to the necessary organs that will filter them out. Without a way to dispose of waste, the body will eventually die.
