True or false and explain why

______________ is a kind of spontaneous mutation that results from a short-term, reversible phenomenon that leads to abnormal base pairing during DNA replications, followed by another round of DNA replication which results in one of the two daughter DNA molecules containing a point mutation. Group of answer choices Tautomeric shift Frameshift mutation Nonsense mutation Pyrimidine dimer Conditional mutation

Please answer this question. I mainly want part A, but if you could answer part B as well, I would really appreciate it.

True or False: there are three different start codons in the genetic code
