Answer:
If the electron transport system did not work, electrons from PSII would not be transferred to PSI. Ferredoxin would then have no electrons to transfer to NADP+ so NADPH would not be produced. This would also affect the light-independent reaction of photosynthesis because NADPH is needed in this reaction.
Explanation:
Edgenuity's Answer.
The correct answer is d: cDNA.
<span>cDNA or complementary DNA is DNA synthesized usually from messenger RNA (mRNA) by the enzyme reverse transcriptase. Because this molecule is from mRNA it contains only exons. cDNA is also produced naturally by retroviruses, for example, HIV virus.</span>
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.
Answer:
1 new DNA molecule, 1 old molecule is conserved
Answer: Option D.
The transfer of the methyl group from adomet to an acceptor yields s adenosylhomocysteine.
Explanation:
S- adenosine methionine is a co substrate and one of the naturally occurring sulfonium ions in the body. It is synthesized from methionine which is abundant in animal derived protein. It is metabolised in the liver where it is converted to S adenosine methionine by the enzyme methionine adenosyltransferase. It involve the transfer of methyl group. It is use in medicine as alternative aid to reduce depression.
