Exp:C Telomeres are controlled by the presence of the enzyme telomerase. A telomere is a repeating DNA sequence (for example, TTAGGG) at the end of the chromosomes. Telomeres act as cap that protect the internal regions of the chromosomes, and they are worn down round of DNA replication. They also stop chromosomes from fusing with each other.

Role of microtubules :
1 To help in cell division
2 Cell membrane formation
3 Respiration
4 Pinocytosis
Explanation:
Exp:A Microtubules are thread like structures and part of cytoskeletion that provide structural support to the cell - They are made up of tubulin protein. - They also help in cellular movements and movements of chromosomes during cell division by forming spindle and astral ray. They play role in cell differentiation and determination of polarity

Microtubules absent in : -
1 Mitochondria
2 Flagella
3 Spindle fibres
4 Centriole
Explanation:
Exp:A Microtubules are absent in mitochondria. Mitochondria are double membrane, semiautonomous eukaryotic cell organells whose function is cellular respiration. Microtubules are present in centriole, flagella and spindle fibers.

The scientific term which is not related to the primary constriction of a chromosome is:
1 centromere
2 kinomere
3 kinetochore
4 chromomere
Explanation:
Exp:D Centromere, Kinomere Kinetochore all are the site of primary constriction of a chromosomes. Chromomer are regions of chromatin that have been compacted through localized constriction.

Function of telomeres in nucleus:
1 Pole ward movement
2 To initiate the RNA synthesis
3 To seal the ends of chromosome
4 To recognize the homologous chromosome
