Answer:

RNA

Explanation:

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

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

The CRISPR system involves the cas9 enzyme, which identifies specific nucleotides to be cut using RNA molecule as a guide to identify the proper DNA sequence to edit.

Further Explanation:

CRISPR methodology is a very powerful as well as simple technique that helps in editing genomes. It allows scientist or researchers to modify the sequences of the DNA and alter the function of a gene. CRISPR system was discovered by a Japanese scientist. Mainly bacteria and other prokaryotes have CRISPR machinery in their genome.

Scientist makes a very small section of RNA with short sequence that mainly attach to a particular sequence of a DNA in the genome. RNA sequence attaché to the enzyme called Cas9. In CRISPR machinery, Cas9 is a protein act as a molecular scissors, and capable of cutting the strands of DNA. In bacteria, the changed RNA is widely used to identify the sequence of the DNA and then Cas9 enzyme cuts the DNA at a particular location.

In Oompa Loompas, gray face (G) is dominant to orange recessive face (g). If two gray faced Oompas have an offspring with an ora
Neko [114]

Answer:

The genotype for each of the parents must be

parent 1 : Gg

parent 2 : Gg

Explanation:

Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.

Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross

                                 G           g

G                                GG       Gg

g                                 Gg        gg

from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
