The chemical code in DNA is formed from
How nitrogenous bases are arranged
How sugars & bases are arranged
How phosphates & sugars are arranged
How chromosomes are arranged
The reason why DNA is crucial to living things is that:
DNA is what holds the genetic code for organisms
DNA is shaped like a spiral helix
DNA can keep people from getting sick
DNA can break apart
Which of these pictures shows the correct structure for DNA?
If scientists manipulated the genes of a tomato plant so it would grow cube-shaped tomatoes, what would this be an example of?
Genetic engineering
Trait extraction
DNA replication
Chromosome mutation
Which of the following was Rosalind Franklin's contribution to the study of genetics & heredity?
Taking X-ray pictures that showed the structure of a DNA molecule

What is the correct rule for matching up nitrogenous base pairs?
