Here are some of the tRNA molecules in Lucy's white blood cells. Let's see if tRNA #1 is carrying the correct amino acid for its anticodon. Using the RNA Pairing Rules, find the correct codon for this tRNA's anticodon.

A ↔ U
G ↔ C

For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).

Explanation:

Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.

The RNA pairing rules is that each nitrogenous base has a complementary base, so:  

- Adenine is complementary with uracil A=U

- Cytosine is complementary with Guanine C=G

In this case, it can be seen that:

explanation:

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
