D., it increases the biodiversity of the species
The question lacks the diagram. The diagram has been attached below.
Answer:
1.
Explanation:
Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.
The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.
Thus, the answer is 1.
Answer:
Mechanical
Explanation:
I hope this will help you
Answer:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
Explanation:
cDNA is the acronym for complementary DNA. This DNA is a single or double stranded moolecule that is synthesized from a messenger RNA molecule. This molecule is used in studies that aim to clone eukaryotic genes in prokaryotic individuals. The result of this is the expression of a protein from a eukaryotic individual in prokaryotic individuals.
To form a double-stranded cDNA molecule, the following steps would be required:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
<h3><u>Answer;</u></h3>
2.It serves as the final acceptor for electrons from the electron transport chain.
<h3><u>Explanation;</u></h3>
- Cellular respiration is the process by which glucose or other organic compounds such as fructose are broken down to generate energy in the form of ATP, that is required to drive cellular or body processes.
- Cellular respiration takes place in the presence of oxygen and occurs in three stages, namely; glycolysis, kreb's cycle and electron transport chain. The end products of cellular respiration is energy in the form of ATP, and water and carbon dioxide as a byproduct.
- The oxygen consumed during cellular respiration is directly involved in accepting electrons at the end of the electron transport chain
