Which of these is happening when translation takes place?

A. DNA is being replicated.
B. tRNAs are bringing amino acids to the ribosomes.
C. mRNA is still in the nucleus.
D. rRNAs expose their anticodons.

Respuesta :


The answer is B

Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes

mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of  protein synthesis.

Based on the translated information, tRNA then fetches amino acids  from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.
