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

Kitty [74]

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

Although most thunderstorm cells complete their life cycle in 30 minutes, thunderstorm weather may persist at a specific locatio

mylen [45]

The thunderstorm is more likely to remain in the area for longer periods of time if mountains are present. The air is forced up the mountain, and the instability and moisture remain, meaning the thunderstorm persists.

The convection currents that exist between the cold and hot air due to density differences may also remain, which means that the thunderstorm weather will also remain.
