Answer:
Alternative splicing occurs.
Explanation:
The human genome comprises of a large number of introns or no protein-coding sequence interspersed between the exons or the protein-coding sequence.
After transcription in eukaryotes, an event takes place called splicing which removes all the introns from the mRNA and joins exons and additionally alternative splicing takes place which joins together many exons in many combinations which produce a variety of processed mRNA and thus a variety of proteins.
The process of alternative splicing produces a lot more than proteins from a single gene product.
Thus, alternative splicing is correct.
Recessive<span> and </span>dominant alleles<span>. You will recall that genes have </span>different<span> forms called </span>alleles<span>. An </span>allele<span> can be </span>recessive<span> or </span>dominant<span>. A </span>recessive allele<span> only shows if the individual has two copies of the </span>recessive allele<span>.</span>
Answer:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.
Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
