Which hip bone forms the superioir part of the pelvic girlde that extends upward from the acetabulum
Mars2501 [29]

The ischium bone forms the superior part of the pelvic girdle.

<h3>What is the structure of the pelvic girdle?</h3>

In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.

The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

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:

  • <em>For the anti-codon:  CCA</em>
  • <em>Codon:                      GGU</em>
  • <em>Aminoacid:               Gly</em>
