denis-greek [22]

People with central sleep apnea experience a complete cessation of respiratory activity for brief periods of time yet do not have frequent awakenings and do not tend to feel tired during the day.

<h3>What is sleep apnea?</h3>

Breathing regularly stops and starts during sleep, which is known as sleep apnea. People may have sleep apnea if they snore loudly and still feel exhausted after a full night's sleep.

These are the primary forms of sleep apnea:

The more prevalent type of obstructive sleep apnea happens when throat muscles relax.

Central sleep apnea, which develops when your brain fails to properly activate the breathing muscles,

When a person has both central and obstructive sleep apnea, it is known as complex sleep apnea syndrome, also called treatment-emergent sleep apnea.

How would you change your model to show what happens when the other cell receives the protein?
GREYUIT [131]

Another cell that shows the process of endocytosis should be drawn. When the second cell receives the protein, the model will show a folded plasma membrane around the protein. The model will show the membrane bringing the protein into the cell.

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.
