Answer:
A) mRNA
B) rRNA
D) tRNA
Explanation:
The three main types of RNA directly involved in translation are:
messenger RNA (mRNA),
ribosomal RNA (rRNA), and
transfer RNA (tRNA).
messenger RNA (mRNA) transmits information from DNA to the ribosome for translation to occur. They serves as instruction to make a protein.
ribosomal RNA (rRNA) as the name implies, composed about 60% of ribosome by mass. They provide location where mRNA binds and catalyze the formation of peptide bond with the use of peptidyl transferase.
transfer RNA (tRNA) carries the correct amino acid to the site of protein synthesis in the ribosome. An alternation in the tRNA can result in global problems for the cell because it is required for proper translation process.
