So that they can prove the other scientists views wrong and develop a new theory in which there is more sense and credibility.
This is because the cilia cells are in desperate need of energy. They get this source of energy from the mitochondria. Also, goblet cells have ribosomes because they need proteins and catalysts to function
Are you sure this isn't a physics question?
Higher pitched sounds have waves of a higher frequency and they have shorter wavelengths.
Hope that helps.
Tissues invaded by viruses, which attempt to replicate themselves by taking over cellular machinery, secrete small proteins called <span>interferon</span> to protect nearby cells and hinder further multiplication of the viruses.
Answer:
a) the pyrimidine ring is assembled before being bonded to the ribose phosphate, whereas the purine ring is bonded to the ribose phosphate as it is formed
Explanation:
There are two ways for the synthesis of purines and pyrimidines:
- de novo synthesis-from basic simple units
- "recycling" synthesis-reuse of metabolites
Purines are synthesized directly on ribose sugar, in segments.
Pyrimidines are attached to the ribose after the synthesis of the base.
