Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phospha
SVEN [57.7K]

Answer:

30 protein molecules per mRNA molecule

Explanation:

In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

A _______ is a segment of a chromosome that codes for a specific protein.
Alex Ar [27]
<span>The correct answer is gene. Genes are carriers of the genetic material that get transferred from a parent to an offspring after sexual reproduction. If the proteins and the codes are synthesized badly, things like genetic disorders are created and these are diseases that get transferred from a parent to a child like Huntington's disease or anything similar.</span>
