Answer:
b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Explanation:
Hello,
In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Best regards.

Answer: The correct sequence for the protein creation is as follows-
1) Information is transcribed in DNA to mRNA.
2) mRNA leaves the nucleus.
3) Ribosome attaches to the mRNA.
4) tRNA anticodon carries an amino acid that compliments the mRNA codon.
5) The chain of amino acids forms a protein.
According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.
The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.
This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.
Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).
Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.
