Answer:
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:
Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.
Explanation:
The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.
There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
