List of top Questions asked in CUET (PG)- 2026

Assertion (A): Molecular evidence suggests the sister group of sponges is Mesomycetozoa, not choanoflagellates. Reason (R): Sponge collar cells resemble choanoflagellates, suggesting a common ancestor.
Assertion (A): Isoelectric focusing (IEF) is a highly sensitive analytical technique particularly useful for studying micro-heterogeneity in a protein. Reason (R): A protein may show a single band on SDS gel, but three bands on an IEF gel. The method is useful for separating isoenzymes.
Assertion (A): The transcripts of RNA polymerases I and III are not processed. Reason (R): RNA polymerases I and III lack a C-terminal domain (CTD).
Assertion (A): Lack of insulin or thyroid hormone increases blood cholesterol, whereas excess thyroid hormone decreases it. Reason (R): These effects are probably caused by changes in the degree of activation of specific enzymes responsible for the metabolism of lipid substances.
Assertion (A): The two alleles of a gene segregate from each other into the gametes; so half the gametes carry one allele of the pair and the other half carry the other allele. Reason (R): The union of one gamete from each parent to form the zygote is random.
Assertion (A): A character showing continuous variation has an unbroken range of phenotypes in a population. Reason (R): Differences are caused by allelic variation in one or many genes, while in some cases, all variation is environmental and has no genetic basis.
Assertion (A): Scleroderma is a systemic autoimmune disease. Reason (R): In Scleroderma, immune response is directed toward nuclei, heart, lungs, kidney and gastrointestinal tract.
Below given structure is of:
Given below are two statements: Assertion (A): Caveolae are enriched in cholesterol and glycerophospholipids. Reason (R): Caveolin binds cholesterol in the membrane and forces the associated lipid bilayer to curve inward to form caveolae.
Assertion (A): Innate immunity includes built-in molecular and cellular mechanisms that are encoded in the germline and are evolutionarily more primitive. Reason (R): Immune responses by B and T lymphocytes are much more attuned to subtle molecular differences and more antigen-specific.

Some animals living in the same habitat with inedible species sometimes evolve a coloration that resembles the warning coloration of a toxic species, then it is called:
