Intro to DNA Vocab

Question 1

A twisted ladder shape of DNA molecules. Composed of two strands of DNA that wind around one another, with the nitrogenous bases on the inside which forms a hydrogen bonds that hold everything together.

Answer 1

Double Helix

Question 2

Forms two complementary nitrogenous bases joined together by hydrogen bonds.

Answer 2

Base Pair

Question 3
