Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.
The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.

The most common organisms with exoskeletons are arthropods which include insects (bees, ants), arachnids (spiders) and crustaceans (lobsters and crabs).
Answer:Prokaryotes are organisms whose cells do not contain a distinct nucleus, bounded by a nuclear envelope, in contrast to eukaryotic organisms that do have distinct nuclei. Prokaryotes include both the bacteria and the archaea, which appear to be only distantly related to bacteria.
Explanation:
Viral DNA can be inserted into the genome of bacteria by manipulating a specific enzyme known as DNA ligase.
<h3>What is DNA ligase?</h3>
This is a special enzyme found in humans and other forms of DNA. The role of the DNA ligase enzyme is to fuse together distinct strands of DNA. By manipulating this enzyme, scientists have achieved genetic modification.
Therefore, we can confirm that due to the successful manipulation of an enzyme known as DNA ligase, scientists have been able to insert viral DNA into the genome of bacteria.
