Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body.
Arterias, venas y capilares.
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
Answer:
Prokaryotes are simple cells that lack a nucleus or membrane-bound organelles. A nucleus is a type of organelle that holds DNA. In prokaryotes, however, their DNA floats in the cytoplasm in a nuclear region rather than being contained in a nucleus.
Explanation:
the answer is A because A always goes with T
