Short Answer Type Questions

Question. Mention about the synaptonemal complex.

Answer. Synaptonemal complex is a protein complex, visible with the electron microscope, that is the physical basis of the pairing of homologous chromosomes (synapsis) during meiosis. It assembled during zygotene as homologous chromosomes pair up, and it disassembled during diplotene as homologous chromosomes separate.

Question. Complete the following sentences with suitable words.
(i) Chromosome condensation occurs during ________
(ii) _________ is marked by the alignment of chromosomes at the equatorial plate.
(iii) _________ is the equational division in which the chromosome number of the parent is conserved in the daughter cell.
(iv) Each parent cell has a pair of _________ chromosomes.

Answer. (i) prophase (ii) metaphase (iii) mitosis (iv) homologous

Question. Discuss about the attributes does a chromatid require to be classified as a chromosome.

Answer. In telophase-I of meiosis-I, chromosome number becomes half but the chromosomes are still composed of two chromatids. If crossing over occurred, these chromatids are not genetically identical. They divide in second meiotic division. Hence, crossing over is an attribute, which classify chromatids as chromosomes.

Question. Distinguish anaphase of mitosis from anaphase-I of meiosis.

Answer. Differences between anaphase of mitosis and anaphase-I of meiosis are as follows :

Question. Why do the chromosomes become short and thick in prophase?

Answer. The chromosomes become short and thick in prophase because it is physically easier for short and compact chromosomes to move through the cytoplasm than the very long and twisted interphase chromosomes.

Question. Both unicellular and multicellular organisms undergo mitosis. What are the differences, if any, observed in the process between the two?

Answer. In unicellular organisms, mitosis is a method of asexual reproduction. E.g., in bacteria, mitosis results in formation of identical daughter cells. However in multicellular organisms, mitosis helps in growth and repair of cells and tissues. E.g, Repair of damaged skin through production of new skin cells.

Question. Give examples where the four daughter cells from meiosis are equal in size and where they are found unequal in size.

Answer. During formation of male gametes (i.e., spermatozoa) in a typical mammal (i.e., human being), the four daughter cells formed from meiosis are equal in size. On the other hand, during formation of female gamete (i.e., ovum) in a typical mammal (i.e., human being), the four daughter cells are unequal in size.

Question. In which phase of meiosis are the following formed?
(i) Synaptonemal complex.
(ii) Recombination nodules.
(iii) Appearence/activation of enzyme recombinase.
(iv) Terminalisation of chiasmata.
(vi) Formation of dyad of cell.

Answer. (i) Zygotene
(ii) Pachytene
(iii) Pachytene
(iv) Diakinesis
(v) Anaphase-I

Question. How do cell stop dividing?

Answer : When cell enters in G0 Cycle

Question. Which stage of meiotic division last for years in some vertebrates. Explain some features of this stage.

Answer : Diplotene of meiosis

Question. Complete the following figure for Cell Cycle.

Answer : G0 , S, G2
