Answer:
To understand the correct answer, let's break down the given information and analyze each component.
Synthesis of RNA with a copolymer of UGUGUGUGUG:
Khorana et al synthesized RNA using a copolymer of UGUGUGUGUG. This means that the RNA strand was composed of repeating units of UG. Each UG unit corresponds to a specific codon in the RNA sequence.
Production of a peptide with alternate cysteine and valine:
During translation, the RNA sequence is decoded to produce a peptide chain. In this case, the peptide chain consists of alternate cysteine and valine amino acids. To determine the codons that code for cysteine and valine, we need to refer to the genetic code.
Genetic code:
The genetic code is a set of rules that determines the correspondence between codons (sequences of three nucleotides in RNA) and the amino acids they code for. Here are the codons for cysteine (Cys) and valine (Val):
- Cysteine (Cys): UGU and UGC
- Valine (Val): GUU, GUC, GUA, and GUG
Determining the codons for cysteine and valine:
To produce a peptide with alternate cysteine and valine, we need to identify the codons in the RNA sequence that correspond to these amino acids. From the genetic code, we can see that:
- UGU codes for cysteine
- GUG codes for valine
Therefore, the correct answer is option D: UGU and GUG. These codons would appear in the RNA sequence synthesized by Khorana et al, resulting in the production of a peptide with alternate cysteine and valine amino acids.
