The subunits of DNA
What are nucleotides?
This looks like DNA, but it only has one strand.
What is RNA?
A change in DNA caused by random genetic error or mutagens.
What is a mutation?
The three parts of a nucleotide.
What are a sugar, phosphate, and base?

The type of RNA that travels from the nucleus to the ribosome. It starts the whole process of protein synthesis!
What is mRNA?
(What is messenger RNA?)
The mutation in which one base is replaced by another base.
What is substitution?
Watson & Crick gained great heights in the field of genetics by discovering that DNA was in this shape.
What is a double-helix?
(What is a ladder?)
What is rRNA?
(What is ribosomal RNA?)

The type of mutation in which one extra base is added.
What is insertion?
1 string of nucleotides makes these for us.
What are genes?
The type of RNA that brings amino acids to the mRNA once it is in the ribosome.
What is tRNA?
(What is transfer RNA?)
The type of mutation in which a base is missing.
What is deletion?
Nucleotides make up DNA molecules. They are in the shape of a ladder (as shown below.)
The sides of the ladder are made up of these.

What are sugars and phosphates?
The base that is found in RNA that is NOT found in DNA. (And, yes, you must know the actual word- not just the letter!)
True or false: All mutations are harmful.
What is "false"?
