Answer:

they can insert the codon that encodes phenylalanine by CRISPR-Cas mediated homology-directed repair

Explanation:

The CRISPR (clustered regularly interspaced short palindromic repeats,)-Cas (CRISPR-associated protein) is a versatile technology for genome editing which has been developed by adapting a natural defense mechanism found in prokaryotic organisms. The CRISPR-Cas genome editing tool can be used to edit DNA sequences in eukaryotic genomes (for example, in human genomes) and thus restore gene function (in this case, the CFTR gene function). The system consists of a Cas protein that cleaves the DNA at specific genomic sites and a single guide RNA (sgRNA) that guides the Cas protein at specific genomic locations. CRISPR-Cas mediated homology-directed repair refers to the process where Cas cuts the DNA to triggers the homologous recombination (HR) DNA repair pathway, by which it is possible to insert new genetic sequences at specific genomic sites (in this case, the codon that encodes phenylalanine within the specific CFTR gene).

If 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution, what is the concentration of CH3OH in the solution?​
astra-53 [7]

The concentration of CH3OH in the solution is 2.18M

HOW TO CALCULATE MOLARITY:

  • The molarity of a solution can be calculated by dividing the number of moles by its volume as follows:

  • Molarity {M} = no. of moles (mol) ÷ volume (L)

  • According to this question, 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution. The number of moles of methanol is calculated as follows:

no. of moles = 35g ÷ 32g/mol

no. of moles = 1.09mol

  • Molarity = no. of moles ÷ volume

Volume = 500mL = 0.500L

Molarity = 1.09mol ÷ 0.500L

Molarity = 2.18M

Therefore, the concentration of CH3OH in the solution is 2.18M

Members of Chondrichthyes are thought to be descended from fishes that had ________.
ella [17]

The correct answer is B. A bony skeleton

Explanation:

In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.

The patient is recovering from hypovolemic shock. The nurse hangs a bag of normal human serum albumin (Albutein) and educates th
FinnZ [79.3K]
<h3> It is a protein that pulls water into my blood vessels.</h3>

Explanation:

Hypovolemic shock is a life threatening condition that results in severe dehydration of the body or extreme blood loss. Hypovolemic shock causes blood volume to decrease to an extent where heart is unable to pump it.

Hypovolemic shock is such a critical condition where multiple organ failure may occur. It is often treated with intravenous rehydration therapy.

Serum albumin is a common compound which is given to a shock victim as it has the capability of pulling water into the body hence, restoring the blood volume.

So when patient says that "It is a protein that pulls water into my blood vessels." Shows that he understood what nurse taught her.

Place the

I THINK:

The DNA strands unwind, and
RNA polymerase binds to the
template strand.

The tRNA moves through mRNA
with the activated amino acids
attached to it.

The synthesis of mRNA begins.
The amino acids assemble
to form peptide.

The mRNA undergoes intron
splicing and exits the
nucleus.
