Chapter 5, Problem 2SA
Summary Introduction
To analyze:
What percentage of bases would you expect thymine to be, if 20% of the bases are cytosine; why?
Introduction:

Students have asked these similar questions
A double-stranded DNA molecule is 1 cm long, and the percentage of adenine is 15%. How many cytosines does this DNA molecule contain?
If you analyze a double-stranded DNA molecule and find that 15% of all the nucleotide bases are
Adenines, you know that there must also be [ Select ]
Thymines,
[ Select ]
Guanines, [ Select ]
v Cytosines and
[ Select ]
Uracils. (Count each of the bases in any double stranded DNA molecule
and calculate their percentages to find the simple key for this if you haven't seen it yet.)
How many possible nucleotide sequences are there for a stretch of DNA that is N nucleotides long, if it is (a) single- stranded or (b) double-stranded?
