The nucleotide sequence of a dna codon is gta. what would be the nucleotide sequence of an mrna molecule transcribed from this dna? in the process of protein synthesis, a trna pairs with the mrna codon. what is the nucleotide sequence of the trna anticodon that corresponds to this mrna codon? what amino acid is attached to the trna?

According to the base-pairing rule A form base pair with T with two hydrogen bond and G pairs with C with 3 hydrogen bond in DNA. But in RNA T is replaced by U that means A pairs with U in mRNA.

So according to this the nucleotide sequence of the mRNA molecule transcribed from the GTA codon of DNA will be CAU. tRNA are the molecules that pairs to the triplet codon present on mRNA through its anticodon loop which have nucleotide sequence just opposite to triplet codon it binds with.

Each tRNA has attached amino acid according to the anticodon sequence it has. So the anticodon sequence on tRNA will be GUA against the CAU codon sequence of nucleotide on mRNA and this tRNA must be attached with histidine amino acid.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
