19 DNA Nucleotide bases are selective in their bonding Think

19. DNA “Nucleotide bases” are selective in their bonding. Thinking about your readings, and the details discussed in lecture 2~4, what is the corresponding (“mirror image”) sequence of bases for the DNA strand CTAATGT?

In question 19, I stated that the sequence of nucleotide bases was DNA, rather than RNA, but you could have known this anyway, just by looking at the bases that are present. How do you know that this was not a sequence of RNA?

Solution

Answer:

19).

CTAATGT

GATTACA

By looking at the sequence of the nucleic acids, we can know whether that is DNA or RNA. Because, DNA doesn;t have Uracil (U) whereas RNA doesn\'t have Thymine (T). Reaming all bases (A, G, C) are common in both the DNA and RNA.
