Well, scientists are working hard to find out more about cells, so they should know all of the cells. The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it, because it is a part of our bodies, and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to some of the biggest infections ever.
The correct answer in this question is letter B. Through adaptation, an organism increases its chance of survival. This intensifies the fitness of species. A population may lead to extinction if its species did not adapt to the environmental changes.
The correct answer is: The addition of a 7-mG cap at the 5' end of the transcript and the addition of a poly-A sequence at the 3' end of the message
These posttranscriptional processes are called:
• 5’ capping - It protects the mRNA from 5' degradation by exonucleases. Cap is also involved in ribosomal binding.
• Polyadenilation or addition of poly(A) tail – It also protects mRNA from degradation of 3’exonucleases. A long poly(A) tail can also increase translation.
Cholesterol is a lipid that is transported in the blood using different types of lipoproteins. There are three types of lipoproteins that are differentiated based on their density. Very low-density lipoprotein, low density protein and high density lipoprotein are the three most common types. These lipoproteins use the process of endocytosis to form vesicles that allow the transport of the hydrophobic lipids throughout the blood.
