Which of the statements regarding the sequence of events from DNA to RNA to protein to enzyme (hexokinase) is correct? A. The linear sequence of deoxyribonucleotides in the DNA encoding hexokinase is transcribed into an RNA molecule with the complementary ribonucleotide sequence.

B. RNA polymerase I and III together transcribe all ribosomal rRNAs genes.
C. RNA polymerase III transcribes genes for tRNAs.
D. RNA polymerase III also transcribes microRNAs (miRNAs) and long noncoding RNAs (lncRNAs).

B. Phosphorylated mannose residues are recognized by a mannose-6-phosphate receptor in the cis Golgi network.
C. N-linked glycosylation takes place in both endoplasmic reticulum and Golgi body.
D. O-linked glycosylation occurs entirely in Golgi body.

Choose the correct sequence of events on short term endocrine response to stress:

Choose the correct stages in the development of Gastropods to indicate occurrence of torsion:

Choose the correct sequence of events during a Cardiac cycle:

Correct sequence of embryonic developmental stages:

Correct sequence of events in cytosolic pathway of antigen presentation:

Correct sequence of events in mammalian fertilisation:

Choose the correct sequence of enzymes involved in the preparatory phase of glycolysis:

Correct sequence of events on larval development of Herdmania:

True statements about collagen: A. Triple-stranded helical structure
B. Repeating tripeptide Gly-X-Y
C. ‘a chains' are right-handed helix
D. Glycine permits sharp twisting
E. Ascorbic acid is required for proline hydroxylation

Correctly arrange the below given Transcription Factors (TFs) as per their involvement in initiation of eukaryotic transcription:

Choose the correct sequence of events involved in the synthesis of a secretory protein:

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.

Choose the correct sequence of events involved in receptor-mediated endocytosis of transferrin:

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): Scleroderma is a systemic autoimmune disease. Reason (R): In Scleroderma, immune response is directed toward nuclei, heart, lungs, kidney and gastrointestinal tract.
