The passage below describes the stage of protein synthesis known as translation.
Complete the passage by writing a suitable word or words on each dotted line.
Translation begins when the mRNA molecule binds to a ribosome in the cytoplasm. Molecules of ‾\underline{\hspace{3cm}} are responsible for carrying specific amino acids to the ribosome.
Each of these carrier molecules has a specific triplet of bases called an ‾\underline{\hspace{3cm}} that aligns with a complementary codon on the mRNA strand.
When two amino acids are aligned next to each other, an enzyme-catalysed reaction joins them together via a ‾\underline{\hspace{3cm}} bond.
The ribosome, which is made of proteins and ‾\underline{\hspace{3cm}}, moves along the mRNA to translate the next codon.
This sequential addition of amino acids builds a growing polymer called a ‾\underline{\hspace{3cm}} chain.
The elongation of this chain terminates when the ribosome encounters a ‾\underline{\hspace{3cm}} codon, releasing the completed protein.
