Sophie [7]

The correct statements are C The pH is accurate but the solution will have excess salt. D The pH is accurate but the concentration of Tris will be incorrect

Explanation:

As the pH is finally maintained at 7 the pH for the buffer solution will be accurate but excess salt will be produced due to use of Both NaOH and HCl to make up the to 7.

Leni [432]

Answer:

Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.

You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.

If the code reads. CGC GCG CGC GCG etc.

The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.

</span><span>The cycle cycle; mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells.</span>
