Question
Codon bias can be seen in a genome i. What causes the higher mutation rate from G to A and C to T? ii. What causes the higher frequency of select tBNAs within a cell? ii. Why are some codons less prone to translation errors? Gene trafficking has occurred multiple times in evolutionary history, including the transfer of multiple genes required for the large, quaternary-structured RUBISCO from the plastids to the plant nucleus. From an evolutionary standpoint, what BENEFIT is derived from the plant from having to produce some of the individual proteins for this important plant enzyme? Sulfate must be reduced to sulfite before it can be metabolized to produce sulfur-containing chemicals (such as the amino acid cysteine). What evolutionary benefit would be provided to the plastid for being the sole site for sulfate reduction in plants? i. ii.Explanation / Answer
Codon bias:
iii) A codon contains three letters and when the third letter is changed, it still codes for the same amino acid.
Example : CUU, CUC, CUA and CUG codes for amino acid leucine.
