Which of the following statements is not correct?
1 A single human cell has 2 m long thread of DNA
2 Part of chromosomes after second constriction is called telomere
3 Centromere forms first site of constriction
4 Chromatin consists of DNA, RNA, histones and non-histones
Explanation:
Telomeres, the repetitive DNA repeat sequences at the end of linear eukaryotic chromosomes protecting chromosome ends from degradation and illegitimate recombination, play a crucial role in cell fate and aging.
