Complete the sentence. Histone proteins increase the transcription rate for a particular gene. stabilize condensed chromosomal DNA during transcription. bind tightly to DNA and strengthen hydrogen bonds between bases. regulate gene expression by reducing the rate of transcription.

stabilize condensed chromosomal DNA during transcription.

Explanation:

Histones are the proteins that are involved in the packaging of DNA in the nucleus. The histones are basic and are positively charged proteins that form the core and allows the wrapping of the DNA around it.

This wrapping around the histones forms nucleosome structure which further compact to form the chromosomes. The studies on histone proteins have suggested that they stabilize the condensed DNA during the process of transcription which is related to the gene expression.

Thus, the selected option is correct.
