How is protein synthesis different in prokaryotes and eukaryotes?
Viktor [21]

Answer:

The correct answer is option B

Explanation:

Translation is the process of synthesis of proteins from mRNA in organisms  and transcription is the process of synthesis of mRNA from DNA.

Both prokaryote and eukaryotes shows the presence of translation but both shows many differences in the process of protein synthesis like site of transcription and translation as in eukaryotes transcription takes place in nucleus while translation takes place in cytoplasm. Since prokaryote lacks the nucleus, both transcription and translation takes place in cytoplasm and lacks the process related to post-translational modifications due to which they take place at the same time.

Thus, option B  is the correct answer.

The answer is postovulatory.

The postovulatory phase is also known as Luteal phase because of the corpus luteum which develops from the leftover follicle. As the name suggests, the postovulatory phase occurs after ovulation. In the ovulation phase, an egg (ovum) is released from ovaries. In the postovulatory phase, leftover follicle transforms into the corpus luteum which can end up in either degradation or pregnancy.
