Explanation: 

Detailed explanation-1: -After reading our mRNA transcript and using the table provided, we have now determined the correct sequence of amino acids. Reading from the five prime to three prime direction, the sequence the codons will be translated into is methionine, valine, histidine, leucine.

Detailed explanation-2: -The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins. Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.

Detailed explanation-3: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

Detailed explanation-4: -These two processes are summed up by the central dogma of molecular biology: DNA
