DNA
The genetic material in cells is stored in here.
DNA
What is the process in which DNA molecules divide called?
Replication
What do you call a change in the number, type, or order of bases in a strand of DNA ?
Mutations
What is RNA?
RNA is a molecule that uses genetic information stored in DNA to build proteins.
What molecule in cells carry out the instructions assigned by DNA?
Protein.
Which happens first: DNA splits, or new bases attach to exposed bases?
DNA splits
What are the three types of mutations?
Deletions, insertions, and substitutions
How many different types of RNA are there?
3
How many people made major discoveries about DNA?
9.
What base does Adenine pair with?
Thymine
How can mutations happen/What causes mutations to occur?
Exposure to chemicals, physical changes(like over exposure to UV lights) and random errors is replication.
What base does RNA have that DNA doesn't?
RNA contains Uracil while DNA contains Thymine.
What 3 things make up a nucleotide?
A sugar, a phosphate, and a base.
What base does Guanine pair with?
Cytosine
What are genetic disorders?
A genetic disorder is a mutation that ends up harming the normal functions of the cell.
What Is a mRNA?
A strand of bases that await pairing.
When does DNA replicate?
Before a cell divides
Why do the 2 pairs specifically pair with each other?
They're complimentary, meaning that they fit into each other, like puzzle pieces.
What are mutagens?
Agents in the environment that can cause DNA mutations, like chemicals found in ciggarets.
What is the process of making proteins from RNA called?
Translation
