Choose an option with the correct statements from the list below. i. The telomere is heterochromatic in nature. ii. The acrocentric chromosome has centromere close to its end. iii. Satellite is located near primary constriction. iv. Submetacentric chromosomes are L-shaped.
Options
- Ai & ii
- Bii & iii
- Ciii & iv
- Di, ii & iv
Correct answer
D. i, ii & iv
Step-by-step solution
The telocentric chromosome has centromere at the end of the chromosome and in the acrocentric chromosome, the centromere is near the end. These centromeres are present in the primary constriction and all chromosomes have primary constriction but some chromosomes during metaphase also show secondary constrictions that are called a satellite. They are present in some chromosome and help to identify the chromosome from others.
