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.
The answer is A: being familiar with different types of galaxies that exist in the universe
The answer is : The rock cycle is driven by energy from the Sun as well as from the interior of Earth. The sun provides energy for surface processes such as weathering, erosion, and transport. This is the one of the major source of energy for the rock cycle. Weathering happens when there is a interaction with the air, water and organism which cause the rock to break down, and the pieces of rock are carried away by wind, moving water, etc. through erosion.
Answer:
A) Neither; they both have the same frequency.
