Answer:
<h2>A. G¹ phase</h2>
<u>Explanation:</u>
In G¹ phase - RNA and Proteins are synthesised and the volume of Cytoplasm increase.
DNA was found to contain only four different chemical building blocks.
Answer:
c. the specific geographical location where an organism lives.
Explanation:
The ecological niche of an organism includes the habitat where it lives and its place in the community with respect to the other species. It includes various adaptations present in the organism to survive in prevailing conditions, its interaction with other biotic factors of the system, and the pattern of consumption of available resources. Therefore, the ecological niche of an organism defines the space occupied and its functional role in the community irrespective of the type of biome. It does not take account of its geographical location on the earth.
The cells that produce pepsin, an enzyme that breaks down proteins during the digestive process is Chief cells. Pepsin is the main digestive enzyme in the stomach that breaks down proteins. Pepsin is produced by the chief cells in the inactive form pepsinogen, which is then converted to pepsin by the hydrochloric acid from the parietal cells.
Answer:
If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.
Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.
