Structure of DNA
Structure of proteins
Cause and Effect
100
Nucleic acid, genetic material, and hereditary information are all words for what molecule?
DNA
100
What smaller molecule are proteins made of?
Proteins are made of amino acids
100
If the structure of a protein changes, what else changes?
The behavior of the protein or how it interacts with other molecules
300
The DNA bases in a gene are a code for what?
DNA bases are a code for which amino acids the cell combines to make a protein
300
Proteins include amino acids, hormones and receptors, and antibodies. What happens if the shape of a protein changes?
If the shape of a protein changes, it can't do its job in the cell
300
What can cause a missing, extra, or incorrect amino acid to be added to the protein?
A gene mutation (change in DNA bases of a coding region of a gene)
500
What happens when a gene is expressed in a cell?
The cell makes an mRNA copy of the gene, then the ribosome uses the mRNA to make a protein.
500
The sequence of amino acids in the protein determines its...
The sequence of amino acids determines the protein's shape and how it behaves
500
What happens if a molecule is blocking off a gene so the cell can't make an mRNA copy?
The protein is not produced (the gene is not expressed)
