A nucleic acid is made up of smaller units, or building blocks, called ____________________
What are nucleotides
300

Discovered that DNA was the hereditary material with the "blender" experiment using radioactive markers

Who were Hershey & Chase?

300

The type of bond that holds the two molecules together that make up the backbone is? 

What is a covalent bond

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

DNA nucleotides are made up of three components:
What are 1. A sugar 2. A phosphate 3. A nitrogen base (need all 3 to be correct)
400

Showed that DNA and not protein was the "transforming factor" by using two strains of Streptococchus to first show that DNA transformed the bacteria and then showing that protein-destroying enzymes did not stop the transformation.

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)
