Four valves

Heart Valves. The heart has four valves - one for each chamber of the heart. The valves keep blood moving through the heart in the right direction. The mitral valve and tricuspid valve are located between the atria (upper heart chambers) and the ventricles (lower heart chambers).

2. How could one change in a DNA nucleotide alter the formation of the translated protein
vichka [17]

Answer AND Explanation:

Proteins are formed from the translation of mRNA  to amino acid. Each set of 3 nucleotides make up a codon that codes for a specific amino acid. Frameshift mutations can also impact the formation of the protein.  A change in a nucleotide does not always change the amino acid or protein because some amino acids have more than one set of 3 nucleotides that code for them. Valine, for example, is coded for by GUU, GUC, GUA and GUG. A change in the last nucleotide wouldn't affect the amino acid formed. However,GAG codes for glutamic acid.
