1.	In an experiment your germ cell was having a base at its unusual tautomeric state while replication. What could be the maximum percentage of germ cells carrying this mutation?(a) All(b) 25%(c) 50%(d) 75%The question was posed to me during an interview.I'd like to ask this question from DNA Mutation in section DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics
Answer» Right option is (c) 50% EXPLANATION: It has been experimentally SEEN that a mutation can effect at max 50% of the PROGENY cells. This is due to the FACT that there are two DNA strands and only one of them is carrying the mutation. So, only progenies receiving copies of that mutant strand will be mutant i.e. 50%.
