What gives sperms motility​
Mandarinka [93]

Answer:

The tail of the sperm, the flagellum

Explanation:

We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.

Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.  

Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.

Introns must be removed prior to translation of the mRNA. In addition, eukaryotic transcripts (mRNA) have to undergo two more st
Ivan

Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.

<h3>RNA processing:</h3>

1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).

2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.

3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.

4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.

The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.
