A bacterial cell synthesised a polypeptide of 150 amino acids. The gene encoding it has no introns and includes a stop codon; adjacent nucleotides are 0.34 nm apart. 1) Explain the quantitative links between gene, mRNA, tRNA and amino acids in protein synthesis. 2) Find the number of nucleotides in the coding part of the mRNA. 3) Calculate the number of nucleotides and the length (nm) of the (double-stranded) gene. 4) Find the number of tRNA molecules that delivered amino acids in translation. For each part, write out the law or method used (cross scheme, formulas, reasoning) and all calculations step by step.
The AI score is an estimate. In the official exam the written part is marked by BMBA examiners.
