Question

True or False. If the statement is false, rewrite the sentence so that it is a true statement.

1. ATP-chromatin remodeling complexes condense chromatin, resulting is less gene expression.

true

2. In a dividing/mitotic cell, euchromatin is more abundant than heterochromatin.

Answer 1

Ans.(i) ATP- chromatin remodeling complexes condense chromatin, resulting in less gene expression. ( True statement)

Chromatin remodeling is an important mechanism of regulating eukaryotic gene expression, which makes tightly condensed DNA accessible to various regulatory factors, such as transcription factors and components of DNA replication.

(ii) In a dividing / mitotic cell, euchromatin is more abundant than heterochromatin. ( True statement)

Heterochromatin is less abundant,relative to euchromatin, in the large nuclei of active cells than in the small nuclei of resting cells. Euchromatin is active chromatin, containing DNA sequences that are being transcribed into RNA.
