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.
Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:
The Atlantic Ocean
A marshy wetland
Nevada desert
Polar ice caps
<span>When you talk about growth, it refers to
development either in size, state or ability, the capacity. Growth in living
organisms are resulted from acquiring nutrients, being able to function in
adaptation, irritability, reproduction and excretion. On contrary, these functions
are absent in nonliving things. When you say growth in nonliving things it’s
either by addition of matter or magnitude. The process is called accretion but
this doesn’t mean maturation or aging in living organisms. Maybe rusting or
oxidation is caused by the chemical change, toxification but not growth just chemical
reaction. </span>
