The DNA in linear eukaryotic chromosomes is wrapped around proteins called _____________, which keep the DNA from getting tangled and enable an orderly, tight, and efficient packing of the DNA inside the cell. Group of answer choices

Respuesta :

Answer:

The given blank can be filled with histones.

Explanation:

The family of basic proteins, which associate with the DNA in the nucleus and assist in condensing it into chromatin are known as histones. The nuclear DNA does not come in the form of free linear strands, it is heavily condensed and enveloped around the histones so that to get fit within the nucleus and take part in the generation of chromosomes.  

These are the basic proteins, and because of their positive charge, they get associated with the DNA. Under the microscope, chromatin appears like beads on a string. The beads are known as nucleosomes. Each nucleosome comprises DNA wrapped around the 8 histone proteins, which works like a spool and is known as a histone octamer.  

Histones control the degree of DNA packaging during gene expression processes, therefore they keep the DNA from getting tangled.

What are histones?

  • They are protein molecules found on chromosomes responsible for compacting DNA or providing structural support to a chromosome.

  • They regulate the organization of DNA throughout the cell cycle, that is, they are main proteins in the regulation of gene expression.

Therefore, we can conclude that histones modulate the structure and compaction function of DNA.
