Non-membranous nucleoplasmic structures in the nucleus, are the sites for active synthesis of:

Match List-I with List-II. List-I A. Centromere B. Cilium C. Cristae D. Cell membrane List-II I. Mitochondrion II. Cell division III. Cell movement IV. Phospholipid Bilayer

Cell wall formation in bacteria is facilitated by:

Which of the following statements are correct in the context of Golgi apparatus? A: It is the important site for the formation of glycoprotein and glycolipids B: It produces cellular energy in the form of ATP C: It modifies the protein synthesized by ribosomes on ER D: It facilitates the transport of ions E: It provides mechanical support

Match List-I with List-II: List-I A. Metacentric chromosome B. Sub-metacentric chromosome C. Acrocentric chromosome D. Telocentric chromosome List-II I. Chromosome has a terminal centromere II. Middle centromere forming two equal arms of chromosome III. Centromere is slightly away from the middle chromosome resulting into two unequal arms IV. Centromere is situated close to its end forming one extremely short and one very long arm

The fruit fly has 8 chromosomes (2n) in each cell. During the interphase of mitosis, if the number of chromosomes at G1 phase is 8, what would be the number of chromosomes after the S phase?

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The beginning of diplotene is recognised by the dissolution of the synaptonemal complex and formation of X shaped structures called chiasmata. Reason (R): In oocytes of some vertebrates, diplotene can last for months or years.

Doubling of the number of chromosomes can be achieved by disrupting mitotic cell division soon after:

Given below is a schematic break-up of the phases/stages of cell cycle. Which one of the following is the correct indication of the stage/phase in the cell cycle?
