MRNA, is used to transcript DNA codes from DNA molecules and then later exits the nucleus via nuclear pore, then moves to the ribosome. Then, tRNA is activated to bring specific amino acid to the ribosome for translation. Ribosome, which is the site of synthesis of proteins, is composed of rRNA and ribosomal proteins.
A codon is a three-base sequence (three nitrogen bases in a row) on mRNA. An anticodon is a three-base sequence on tRNA. It matches the codon.
It contains 72 percent hydrogen, 26 percent helium and other elements like oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.
The letter that represents enzyme is B.
Because human DNA is so very long (with up to 80 million base pairs in a chromosome) it unzips at multiple places along its length so that the replication process is going on simultaneously and more accurately.
Answer:
B
Explanation:
I would say this because the pulmonary circulation only transports deoxygenated blood. And this blood gets transported to the lungs so the lungs can absorb oxygen and release carbon dioxide. I am not sure about this one though. This is what I think.
