Can you solve 39-42 please? Thank You

Most of the 20 amino acids are coded for by ________ variations of the genetic code. one two four six The small and large subunits of the ribosome assemble and the first tRNA with the first amino acid arrive tc _______ to initiate translation. the A site the P site the E site the Z site Eukaryote translation initiates with placement of the first amino acid monomer __________. rRNA cystiene AUG methionine tRNA The second and all subsequent amino acids arrive with their tRNAs at ________during the elongation (continuation) phase of translation. the A site the P site the E site the Z site

Explanation / Answer

39) DNA contains 4 nitrogenous bases: adenine, guanine, thymine and cytosine. In RNA thymine is replaced by uracil. These four nitrogenous bases form a triplet codon with different combinations that codes for all 20 amino acids. Therefore, the answer for this question is option c (four).
