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>
Answer:
Identical shape and structure.
Explanation:
Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
Answer: Alzheimer's disease causes proteins in the brain to become improperly folded.
Explanation:
The alzheimer disease is a brain disorder that destroys the memory and thinking skills in the affected patients.
The alzheimer disease is identified as the protein folding disease. It is due to the accumulation of abnormally folded protein called as amyloid beta protein present inside the brain of the alzheimer's patients. The function of this protein is unclear and it is assumed to be involved in the neuronal development.
