Answer:
Cell division is the means of reproduction in unicellular organisms whereas it is the means of tissue growth and maintenance in multicellular organisms. ... In adults, cell divisions are involved in renewing old tissues rather than growth.,ya it is continuously processing
Through air and from falling to the ground and rolling to a more fermented area
<span>DNA, also known as deoxyribonucleic acid, belongs to a class of polymeric organic macromolecules called nucleic acids.
The only other member of this class is ribonucleic acid, or RNA.
Nucleic acids were first discovered in 1869 by the Swiss scientist
Friedrich Miescher.
</span>
<span>DNA and RNA play
important roles as genetic information carriers in biology, enabling the
mechanisms of heredity and protein synthesis. Nucleic acids are
polymers of nucleotides, which are composed of a five-carbon sugar, also
called a pentose sugar, a nitrogenous base and a phosphate group. The
sugar is deoxyribose, in the case of DNA, and ribose, in the case of
RNA.</span>
The correct answer is the last statement.
If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.
It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.
In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
A. cuz it adds genetic diversity
