The mitochondrial DNA helicase has 612 amino acids. What is the length of the mRNA from this protein is translated ? Show your w
NeTakaya
The answer is 1836 nucleotide bases.

<span>It is known that three nucleotide bases in mRNA are called codon and that each codon codes for the specific amino acid. For 3 nucleotide bases in mRNA, there is 1 amino acid in a protein. So, there are 3 times more nucleotide bases in mRNA than amino acids in the protein. This can be represented mathematically:
3 nucleotide bases : 1 amino acid = x nucleotide bases : 612 amino acids
3 nucleotide bases x 612 amino acids : 1 amino acids = x </span><span>nucleotide bases
x nucleotide bases = 612 x 3 nucleotide bases
x nucleotide bases = 1836 nucleotide bases.
So, mRNA long 1836 nucleotide bases will give a protein with 612 amino acids.</span>

What do all macromolecules have in common with each other
ohaa [14]

Answer:

They have approximately similar molecular weight, chemical composition and solubility.

Explanation:

Macro molecules are bigger molecules having more weight. The molecular weight of the macro molecules is more than 10,000 Dalton. They are chiefly the carbohydrates, proteins, lipids, and nucleotide. These are found in the acid-insoluble pool. This means all macro-molecules are acid insoluble. They are all polymers. Their composition is similar, having carbon and hydrogen which forms bonds with other compounds like nitrogen, sulphur, phosphate, OH, etc. They are all basic components of the cell and cell membrane and all are organic molecules.
