Messenger RNA (mRNA) is a single-stranded molecule that passes through nuclear pores into the cytoplasm to ribosomes situated on the endoplasmic reticulum. The triplet codons are read from mRNA as it passes through the ribosome. The function of tRNA is like that of a wheelbarrow as it brings the correct
amino acid to the work site at the ribosome for protein synthesis.

Complete the following blanks with the correct terms.


A tRNA (UGA) carries as its load, only the amino acid called _ 1  . It plugs into the ribosome because its _ 2  , (UGA), matches the mRNA codon   3   (letters).
A different tRNA (GGG) carries only the amino acid   4   and its   5  , (GGG), which allows it to match the mRNA codon   6  .
Another tRNA (CUU) carries the amino acid   7_  and its anticodon (CUU), which allows it to match the mRNA codon   8 _.
Note: Each of these three lines have a similar type of answer for each location. Use this information to help you fill in the answer. For example, The last blank for each line is going to be a three letter code. 4 marks
