Based on your understanding of nucleic acids, what type of bonds form between the CRISPR/guide RNA molecule and the target DNA

Biology

Tanya [424]3 years ago
6 0

Answer:

The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds

Explanation:

The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.

Two rodent populations become separated when a large canyon develops in a previously unbroken forest. When is allopatric speciat
krek1111 [17]

Answer:

Allopatric speciation occurs due to the geographical isolation between individuals of the same species. The geographical isolation can be due to canyon development, mountain formation, migration, etc.  

The geographical isolation gives different environmental condition to the separated population of same species to live which allow these two population to evolve differently and evolve in different species.

So when two population becomes different species and not able to interbreed with each other when give opportunity then the allopatric speciation between the two populations becomes complete.

a) preventing ketosis

b) keeping stools soft

c)trapping cholesterol in pockets in the large intestine

d)Causing fiber to bind with bile and more cholesterol to be excreted

Answer:

Causing fiber to bind with bile and more cholesterol to be excreted

Explanation:

High fiber diet include whole grain cereals, fruits, vegetables, nuts and potatoes etc., when consumed,they bind with cholesterol to aid degeneration in order for excretion to occur.
