The cytoplasmic fragments of the megakaryocytes constitute the platelets, this fragments simultaneously into thousands of new platelet cells, these morphological changes are known as proplatelets.

<h3>What are proplatelets?</h3>

They are cytoplasmic protrusions from which platelets or fragments are going to be detached that end up maturing in the circulation.

<h3>Characteristics of proplatelets</h3>

  • Platelets are formed from the fragmentation of giant cells, which emit cytoplasmic protrusions.

  • Each megakaryocyte has about 6 proplatelets, and each proplatelet houses about 8,000 platelets, these "bags" full of platelets enter the bloodstream where they break, releasing them.

Therefore, we can conclude that the megakaryocytes form the future platelets, these platelets are grouped in cytoplasmic portions, called proplatelets.

Which is the role of restriction enzymes?
dezoksy [38]
Restriction enzymes and or restriction endonucleases are involved at recognizing specific sequence of nucleotides and cutting or splicing them at appropriate regions to produce fragments that can either be sticky ends or blunt ends depending on where they cut and the nature of nucleotides involved within the fragments. They play an important role in genetic engineering, as geneticists can use them for placing into extra chromosomal information and or content of plasmids in certain bacteria, from other sources, for instance antibiotics, grow and or produce many individual colonies of bacteria, isolate them and one would have many sequences for instance that can code for an antibiotic that can be extracted and used further. Assuming the bacteria's plasmid can take in that sequence.

In humans, methylation of chromosomal DNA is a signal that often leads to
Ulleksa [173]

Answer:

The correct answer will be option-formation of heterochromatin

Explanation:

Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.

The methylation of DNA converts the cytosine residues to the  5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.

Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.

Thus, the formation of heterochromatin is the correct answer.

Bicarbonate ions which migrate from red blood cells into the surrounding fluid are replaced by _____ ions.
Mrac [35]

Answer: chloride ions

Explanation:

This movements of  chloride ions  into the blood plasma to replace the outward diffused bicarbonate ions is  called  chloride shift, It  occurs  to restore the blood ionic balance altered by the bicarbonate ions diffusion out into plasma

The same amounts of Chloride ions replaced the lost amount of  bicarbonate ions
