A nucleic acid is made up of smaller units, or building blocks, called ____________________
What are nucleotides
300
What is the name for the base represented by a (G)?
What is Guanine
300

This is the term used to describe when one strand of DNA is matched up with the other strand.  Also means "they go together"

What is complimentary?

300
Thinking back to the twisted ladder analogy, what do the sides of the ladder represent?
What are the backbones of DNA (made up of sugars and phosphates)
300
If one side of a strand of DNA reads ATCGA, use the base-pair rules to come up with the sequence on the other, complementary strand of the same DNA. (Complementary means matching)
What is TAGCT Because... A=T T=A C=G G=C A=T

What were the names of the two scientists who first modeled the structure of a DNA molecule as a twisted, double-helix shape.
Who are Watson & Crick
500
Before anybody knew what the structure of DNA was, or even that bases paired up with each other, we only knew that there were sugars, phosphates, and the nitrogen bases A,G,C, and T in a DNA molecule. The name of the scientist who discovered that the % A equals the % T, and the % G equals the % C was? (Fact used to support the base-pair rules)
Who is Chargaff
