Telophase

In which phase of meiosis are the following formed ? Choose the answers from hint points given below. (a) Synaptonemal complex ..... (b) Recombination nodules .... (c) Appearance/activation of enzyme recombinase.... (d) Termination of chiasmata.... (e) Interkinesis.... (f) formation of dyad of cells.... Hint (a) Zygotene, (b) Pachytene, (c) Pachytene, (d) Diakinesis, (e) After Telophase-I/before prophase of meosis-II, (f) Telophase-I/after meiosis-I

Study the following I. Prophase - Organisation of chromatin into chromosomes II. Metaphase - Alignment of chromosomes on equatorial line within the nucleus III. Anaphase--1-Disjunction of bivalents to form single chromatid chromosomes IV. Telophase -I - Organisation of haploid daughter nuclei with two chromatid chromosome The correct combinations are

Mathc the column I with column II and select the option from given codes. {:("Column I","Column II"),("Synaptonemal complex",(i)"Pachytene"),("Recombination nodule",(ii)"Zygotene"),("Terminalisation of chiasmata",(iii)"Telophase I"),("Formation of dyad cell",(iv)"Diakinesis"):}

Selelct the incorrect mathc regarding mitotic cell division. {:((i)"Prophase",-,"Chromosomes begin to uncoil"),((ii)"Metaphase",-,"Chromatids move aprt"),((iii)"Telophase",-,"The nuclear membrane reappears"),((iv)"Late",-,"Each chromosome consists of two"),((v)"Interphase",-,"Chromosomes are not distinct"):}

A Mitosis produces two identical daughter cell. B Meiosis introduces variation due to gene exchange or recombination. C During anaphase chromosome have two chromatids. D Telophase I may be absent. Choose the option with the correct statements.

Match the column I with column II and select the correct option from the given codes. {:("Column I","Column II"),("Disintegration of nuclear membrane",(i)"Anaphase"),("Appearance of nucleolus",(ii)"Prophase"),("Division of centromere",(iii)"Telophase"),("Replication of DNA",(iv)"S-phase"):}

Match the columns :- {:(,"Column - I",,"Column -II"),((A),"Telophase",(i),"Spindle grows between the centraosomes"),((B),"Anaphase",(ii),"Formation of opposite spindle poles"),((C),"Metaphase",(ii),"Sister chromatids are broken down"),((D),"Prophase",(iv),"Reformation of ER"):}

A cell at telophase stage is observed by a student in a plant brought from a field. He tells his teacher that this cell is not like other cells at telophase stage. There is no formation of cell plate and thus the cell containing more number of chromosomes as compared to other dividing cells. This would result in
