Answer:

Histone

Explanation:

Histones are the proteins that package the DNA in eukaryotes. DNA winds around a core of eight histones creating an structure called nucleosome that determines genome organization. Nucleosomes group and ungroup in an orderly manner allowing gene trasncription or silencing, respectively.

How is mitosis different in plants and animals

ValentinkaMS [17]

Answer:

The most important and observable difference in the plant animal cells mitosis is the cytokinesis. In plants a new cell plate is formed between the daughter cells for the future cell wall, while in animal cells the cell membrane constricts to separates the parent cell into daughter cells.

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.

Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.

Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.
