Exp:C The longest chromosome is seen in Trillium. It is measured \(30 \mathrm{~mm}\) in length. Lilium : It is a flower plants that is a genus of herbaceous flowering plants belonging to family liliaceae. Allium : It is a flower plants that is a genus of monocotyledonous flowering plants with hundreds of species belonging to family Amaryllidaceae.

Centromere is also called :
1 chromomere
2 secondary constriction
3 primary constriction
4 chromocentre
Explanation:
Exp:C Centromere is also called primary constriction, from a mitotic chromosome structure. Where two identical sister chromatids are most closely in contact. In primary construction sister chromatids appear most tightly paired. Secondary constriction : It is not present in all chromosomes. It plays an important role in karyology and cytology.

Telomere repetitive DNA sequences control the function of eukaryote chromosomes because they:
1 Prevent chromosome loss
2 Act as replicons
3 Are RNA transcription initiator
4 Help chromosome pairing
Explanation:
Exp:A - Telomeres are region of repetitive nucleotide sequence associated with specialized protein at the end of linear chromosomes. They are wide spread genetic feature most commonly found in eukaryotes. Telomeres act as cap that protect the internal regions of the chromosomes, and they are worn down round of DNA replication.

The part of chromosome beyond the secondary constriction is known as
1 Telomere
2 Centromere
3 Chromomere
4 satellites
Explanation:
Exp:D Satellite chromosome are chromosome that contain secondary constructs that serve as identification. They are observed in arocentric chromosomes Terminal part of chromosome, i.e., end of chromosome is known as telomere. Centromere - The two chromatids are attached to each other by a narrow area called centromere or primary constriction. Chromomere is one of the small bead- shaped and heavily staining masses of coiled chromatin that are linearly arranged along the chromosome.

Spindle fibre unite with which structure of chromosomes:
1 Chromocentre
2 Chromomere
3 Kinetochore
4 Centriole
Explanation:
Exp:C Kinetochore is a protein like structure that occur on a chromatid during cell division and allows to attached a spindle fiber on chromosome. Chromosomes being attached to the \(\mathrm{J}\) shaped spindle fibres by their centromeres. Two types of spindle fibres can be distinguished as the interpolar fibre, which stretches from the pole to the centromers (kinetochore) of an individual chromosome. The mechanism, by which the chromosomes move and the spindle fibres contract remains unclear.
