Question

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.
Anticodon

CCA

Codon

Amino Acid

RNA Pairing Rules
A ↔ U
​​​​G ↔ C

Answer 1

Answer:

For Anticodon it's: CCA

Codon it's: GGU

Amino Acid it's: Glycine (but when typing in the box for Amino Acid I typed in GGU and it was correct so that's the answer for Amino Acid.)

Hope this helps!

Answer 2

Answer:

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:

• For the anti-codon:  CCA
• Codon:                      GGU
• Aminoacid:               Gly
