Where does the RNA cap go? The tail?
Rufina [12.5K]

Answer:

The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.

The two post-transcriptional modifications are the addition of  7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.

The advantages of capping are:

1. Protection of nascent mRNA from the degradation.

2. Recognition by transcription factors helps in translation.

The advantages of tailing are:

1. Protection of the mRNA from enzymatic degradation in the cytosol.

2. Transcription termination

3. Export of the mRNA from the nucleus

Hormone is controlled by a
Marina CMI [18]

Answer:

Hormones are controlled by a

(negative)

feedback system between the glands that produce this hormone and the  concentration of blood calcium ions. If the level of ions is

(low)

,hormone secretion is increased. This causes  resorption by  cells called

which releases both calcium and phosphate ions into the blood stream.​

Explanation:

Negative Feedback a the process in your body that helps to maintain Homeostasis. If some variable changes a value in your body, like your ion levels,  your glands produce a hormone that causes resorption by  cells. This releases both calcium and phosphate ions into the blood stream and therefore your ion levels go back to normal.

Hope this helps!
