How many hydrogen bonds exist between this DNA strand and it

How many hydrogen bonds exist between this DNA strand and its complementary strand?

5\'-TCTATGC-3\'

Place the steps of the Herhsey-Chase experiment in order from first to last.

-centrifuge to seperate bacteria into a pellet

-measure pellet and liquid for radioactivity

-agitate to seperate cells from phade bodies

-radiolabel phage DNA and phage protein

-mex each type of phage with separate bacteria

Solution

Answer:

1). 17

Two hidrigen bonds between A & T. Theree hidrigen bonds between G & C.

5\'-TCTATGC-3\'

3\'-AGATACG-5\'

2+3+2+2+2+3+3=17 Hydrogen bonds.

2).

(First)radiolabel phage DNA and phage protein---mix each type of phage with separate bacteria-------agitate to seperate cells from phade bodies---centrifuge to seperate bacteria into a pellet--measure pellet and liquid for radioactivity (Last).
