Solved in 3 steps
- TRUE or FALSE a) The deoxyribose connects to N9 of guanine. b) In a dsDNA, a pyrimidine in one chain is always paired with a purine on the other chain because of this arrangement, the molecule is 2nm wide along its entire length. Example is A with G or C with T.A segment of a polypeptide chain is Arg-Gly-Ser-Phe-Val-Asp-Arg. It is encoded by the following segment of DNA: G G C T A G C T G C T T C C T T G G G G A C C G A T C G A C G A A G G A A C C C C T Template strand with its polarity: 3’ C C G A T C G A C G A A G G A A C C C C T 5’ - Coding strand with its polarity: 3’ G G C T A G C T G C T T C C T T G G G G A 5’ Please write out the mRNA sequence generated by the template strand to produce that polypeptide chain.A DNA sequence consists of a string of elements called nucleotides, in a defined order.
