Answer:

The main function of viagra is to relax the muscles of the blood vessels in some areas of the body. It is used for the treatment of erectile dysfunction and for high blood pressure. The component of viagra is a competitor to the enzyme PDE5, breaking down cGMP. In the penis, blood is trapped, which results in the erection being maintained. When cGMP levels decrease, the concentration of calcium ions increases, causing smooth muscle contraction.

The Translation initiated is <u>Option D.All of the listed answers are correct. </u>

At the initiation of translation ribosomes and tRNA bind to the mRNA. tRNA is located at the first docking site of the ribosome. The anticodon of this tRNA is complementary to the start codon of the mRNA where translation begins. After binding to the mRNA, the ribosome initiates translation at the start codon AUG and moves the mRNA transcript one codon at a time until it reaches the stop codon.

When tRNA recognizes and binds to the corresponding codon in the ribosome, it transfers the corresponding amino acid to the end of the growing amino acid chain. tRNA and ribosomes then continue to decode the mRNA molecule until the entire sequence is translated into protein. tRNA acts as an adapter molecule during the translation process. Formerly known as soluble RNA or sRNA. As an adapter, it connects amino acids to nucleic acids.
