Structure
There are this many nitrogenous bases in DNA
What are 4
Adenine pairs with this DNA nitrogenous base
What is thymine
Transcription turns DNA into this
What is RNA
In translation, RNA is turned back into this
DNA
This is a change in the DNA base sequence
What is a mutation
DNA is made of repeating molecules called this
What are nucleotides
Cytosine pairs with this nitrogenous base
What is guanine
This is the shape of RNA
What is a single strand
This is the name we give 3 nitrogen bases that code for an amino acid
What is a codon
This is a type of mutation where only one nucleotide is change
What is a point mutation
This is the full name of DNA
What is deoxyribonucleic acid
This enzyme unzips the parent DNA
What is helicase
This is the nitrogenous base that RNA has in place of thymine
What is uracil
This is how many amino acids there are
What is 20
This is a type of mutation where more than one nucleotide is changed
What is a frame shift mutation
These are what make up the "steps" or "rungs" of the DNA ladder
What are nitrogenous bases
This enzyme matches the base pairs and fixes any uracil that is leftover
What is DNA polymerase
This is the type of sugar that RNA has
What is ribose
There are this many stop codons
What are 3
This is a disease that is caused by a mutation in the DNA that leads to uncontrolled cell division
What is cancer
These are the two molecules that make up the backbone of DNA
What is sugar and phosphates
This enzyme binds the parent strand with newly replicated strand
What is ligase
Transcription occurs in this part of the cell
What is the nucleus
This amino acid is the only one that can start translation
What is Methionine
This is a substance that is known to cause cancer
What is a carcinogen
