Imagine a human protein containing 27 repeats of a simple domain arranged in tandem. In contrast a homolog found in bacteria contain only one domain. what is the minimum number of duplication events that can account for the evolution of this protein since our divergence from bacteria? write down the number
Answer:
Based on the given information:
Explanation:
DNA Duplication can exponentially expand the block and can lead to the generation of tandem repeated arrays.
For example, in this case, number of duplication events to generate 27 repeats of an original DNA segment that encodes a protein domain can be determined as below:
