GRADE 10 CELL DIVISION QUIZ

Chromatin is made up of-

• DNA

• Histone

• Bothe A and B

• None of these

Name the structure which is composed of repeated nucleotide units which in turn is made up of phosphate, pentose sugar and nitrogenous base like Adenine, Guanine, Cytosine and Thymine.

• RNA

• DNA

• Protein

• Phosphoglycerates

Choose the correct option which ensures equitable distribution of DNA molecule in the two daughter cell during cell cycle.

• Interphase-Replication

• Interphase-Transcription

• Prophase-Replication

• Prophase-Transcription

Which among the following events takes place as steps called -Prophase,Metaphase,Anaphase and Telophase.

• Replication

• Mitosis

• Karyokinesis

• Cytokinesis

In which type of cell division the daughter cells will receive haploid number of chromosomes.

• Mitosis

• Meiosis

• Both A and B

• None of these

Which among the following is an incorrect significance of meiosis?

• Crossing over which ensures genetic recombination.

• Formation of gametes due to reductional division.

• Maintenance of normal chromosomal count.

• Replacement of old and dead cells

During which stage of cell division cleavage furrow deepens and causes formation of daughter cells.

• Karyokinesis

• Cytokinesis

• Prophase

• Telophase

A small region which causes two sister chromatids to remain attached -

• Centrosomes

• Spindle fibre

• Centriole

• Centromere

A specific sequences of nucleotides on a chromosomes that encodes particular protein and expresses as some particular feature in our body.

• Alleles

• Nucleotides

• Genes

• Chromosomes.

The following set of event takes place in which phase of karyokinesis- (i)Two sets of daughter chromosomes reaches to opposite poles (ii) Spindle fibers disappear. (iii) Chromatid changes into chromatin fibres. (iv)Cleavage Furrows starts deepening.

• Anaphase

• Metaphase

• Telophase

• Prophase
