which of the following sequences is an example of a point mutation of the dna sequence -A-A-G-T-G-C (1 point) 
a.-A-A-A-T-G-C-
b.-A-A-G-U-G-C-
c.-G-T-A-G-A-A-C
d.-A-A-G-G-T-C-

anonymous · Answer

b because a point mutation is when a single base pair is altered. as you can see all of the others have multiple changes to the original sequence

anonymous · Answer

transcription is the process of making an RNA copy of a gene sequence, 
the correct answer would be a because it needs both the RNA polymerase, the DNA to copy from and the ribonucleotides.
