A segment of DNA has the following sequence:TTGGATGCTGAACCTACGACA. What would the sequence be immediately after reaction withnitrous acid? Let the letters H represent hypoxanthine and Urepresent uracil.B. Let’s suppose this DNA was reacted with nitrous acid. Thenitrous acid was then removed, and the DNA was replicated fortwo generations. What would be the sequences of the DNAproducts after the DNA had replicated two times? (Note:Hypoxanthinepairs with cytosine.) Your answer should containthe sequences of four double helices.

Question

A segment of DNA has the following sequence:
TTGGATGCTG
AACCTACGAC
A. What would the sequence be immediately after reaction with
nitrous acid? Let the letters H represent hypoxanthine and U
represent uracil.
B. Let’s suppose this DNA was reacted with nitrous acid. The
nitrous acid was then removed, and the DNA was replicated for
two generations. What would be the sequences of the DNA
products after the DNA had replicated two times? (Note:
Hypoxanthine
pairs with cytosine.) Your answer should contain
the sequences of four double helices.
