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.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
