Answer: The correct answer for the fill in the blank is B) RNA and Proteins.
Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.
Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).
Thus, the components of ribosomes are RNA and proteins.
Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
Answer:The rocks are smooth due to the water eroding the rocks.
Explanation:
The water slowly takes off minerals of the rocks every time is splashes over them. Over time the rocks bumpy surface would be eroded away giving it a smoother surface.
