Explain how he interaction between mRNA codons and tRNA codons anticodons codes for a specific amino acid
Julli [10]
<span>The interactions between the mRNA codons and the tRNA anticodons  codes for a specific amino acid is by, it is the job of the tRNA to start working after the mRNA has able to have its own complementary copy. The mRNA will undergo to the nucleus and will move out, in order to go the rrna. The three nucleotides codes the specific amino acid of the trna. The trna and the mrna will be matched, it will now release the amino acid in the trna that wil form a peptide bond. When the mrna is able to be decoded to form an amino acid, it will now have the ability to break and make proteins in different structures.</span>

"which list contains only vitamins that do not function as coenzymes in energy metabolism?"
galben [10]
The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
