Hatshy [7]

Answer:

The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.

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:
