Answer:

There are two sets of nerve cells in the hypothalamus that produce hormones. One set sends the hormones they produce down through the pituitary stalk to the posterior lobe of the pituitary gland where these hormones are released directly into the bloodstream. These hormones are anti-diuretic hormone and oxytocin

Answer:

At least 6 were provided:

1. Transcription.

2. Chromatin domains.

3. mRNA degradation.

4. RNA transport.

5. Translation.

6. Post-transcriptional modification.

Explanation:

Chromatin domains.

Changes to the epigenome can result in changes to the structure of chromatin and changes to the function of the genome.

Transcription.

During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript.

Post-transcriptional modification.

is a set of biological processes common to most eukaryotic cells by which an RNA primary transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell.

RNA transport.

mRNA is created during the process of transcription, where the enzyme RNA polymerase converts genes into primary transcript mRNA (also known as pre-mRNA). This pre-mRNA usually still contains introns, regions that will not go on to code for the final amino acid sequence.

Translation.

In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide.

mRNA degradation.

Different mRNAs within the same cell have distinct lifetimes (stabilities). In bacterial cells, individual mRNAs can survive from seconds to more than an hour. However, the lifetime averages between 1 and 3 minutes, making bacterial mRNA much less stable than eukaryotic mRNA.

Xelga [282]
They are usually held out for a period of FOUR TO SIX WEEKS after diagnosis. Splenomegaly is an infectious disease that corrupt the spleen and the enlarged spleen usually persist even after all the symptoms have disappeared. Because of this, athletes should not resume active exercise too soon. Generally, the shortest period after which it is okay to resume active exercise is four weeks after all the symptoms have gone.
