Biology Question on the molecular basis of inheritance
Which of the following occurs more than one and less than five in a chromosome :-
A
Chromatid
B
Chromosome
C
Centromere
D
Telomere.
Answer
Telomere.
Explanation
Solution
Telomeres contain the ends of long linear DNA molecule contained in each chromatid. Before replication there are 2 telomeric ends and after S-phase there are 4-telomeric ends. In a chromosome before S-phase only one chromatid is there. Centromere is also one in a chromosome. Bead like chromomeres are many in number.
