Answer:
Limitation of comparative investigation is that when it is done on a huge population, huge amount cost is required. Explanation: Benefit of comparative investigation is that we can get descrete information about specific breed or species. It is important for the study of behaviour of many organisms.
Answer:
apex refers to the highest point or vertex of a plant stem or root. The shoot apex is where fresh stems, leaves, and other parts of a plant grow after the old parts fall off or dry up.
Explanation:In experiments conducted plants with the apex grows and its height increase while the height of the plant without the apex does not change.In another experiment plant with the apex grows towards the direction of sunlight which is positive phototropic movement and the plant without the apex does not turn towards light.therefore we can conclude there is an effect of the apex on the growth of a plant.
If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.
Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.
The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.
In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).
