Study the following "&" identify the incorrect combination with respect single meiocyte?
(A) Phase: Anaphase-I, Event : Disjunction/ Segregation
(B) Phase: Metaphase-I, Event : One spindle apparatus is formed
(C) Phase: Anaphase -II, Event : Division of centromere
(D) Phase: Metaphase -II, Event : One spindle apparatus is formed

Read the following statements and select the correct option stating which ones are true (T) and which ones are false (F) in metaphase I spindle fibre attaches to homologus chromosome white in metaphase II attaches to chromatids. Chromosome completely decondenese in telophase I. Blvalent is fromed at leptotene stage level become clearly visible in zygotene stage Diakinesis represents transition to metaphase I.

Observe the action potential and state the correct events that occur in Phase I and Phase II .

List the event which occurs during following stages: 1) Zygotene (ii) Pachytene (iii) Anaphase-I

Find out the correct statement(s) from the following I. In animals mitotic cell division is seen in the diploid somatic cells II. Karyokinesis begins with prophase and ends with telophase III. The number of nuclei that get divided in meiosis are three IV. In higher plants single bipolar spindle apparatus is formed during mitosis

Arrange the following steps in correct order: (DNA replication): (I) Topoisomerase stabilises the helix in phases. (II) Okazaki fragments are formed during DNA replication. (III) Helicase unwinds the helix in phases. (IV) Ligase joins the Okazaki segments

Arrange the following events of mitotic cell cycle in correct sequence I. Initiation of spindle formation II. DNA replication III. Disappearance of Golgi complex, E.R and nuclear membrane IV. Movement of chromosome towards the poles V. Decondensation of chromosomes

The following events occur during the various phases of the cell cycle. Name the phase against each of the events. (a) Disintegration of nuclear membrane..... (b) Appearance of nucleolus..... (c) Division of centromere .... (d) Replication of DNA...

List the most important feature of the following stages : (i) S-phase, (ii) Zygotene, (iii) Pachytene: (iv) Anaphase-I
