I don't understand this question, hoping someone can help!
One of the following bases does not belong among pyrimidine bases: - Uracil - Adenine - Cytosine - Thymine
I thought that everyone was bases, expect that uracil is in RNA, and that in DNA it is replaced by guanine.
Also one more question: Which of the processes would never contribute to genetic variation within a bacterial population? - Transformation - Meiosis - Mutation - Transduction
I have a hunch that the right answer is mutation, but I don't know why. If you know the answer, it would be very helpfull if you could explain why :-)
