Which type of bond is responsible for holding complementary base pairs together?

Which of the following shows the correct pairing of DNA base pairs?

Who is credited for the discovery of the DNA double helix?

Which of the following is false regarding the DNA double-helix?

You analyze a double-helix and determine that 17% of the helix is made up of the nucleotide adenine (A). What percentage of the same helix must be comprised of the nucleotide guanine (G)?

In complementary base pairing of DNA, guanine always pairs with __________ and adenine always pairs with __________.

The orientation of the two strands of the DNA molecule are considered to be __________.

Which of the following scientists is credited with discovering the double-helix structure of DNA?

I. James Watson

II. Francis Crick

III. Linus Pauling

The double-helix structure of DNA was discovered using X-ray crystallography (Rosalind Franklin) and elucidated by Watson and Crick. Before this discovery, it was previously known that DNA is comprised of four nucleotide bases: adenine, thymine, guanine, and cytosine. Adenine always binds to thymine, while guanine always binds to cytosine.
