1.3: DNA & The Production of Proteins Flashcards
1
Q
What is DNA made up of?
A
A unique sequence of 4 bases
2
Q
What does DNA coil into?
A
Chromosomes
3
Q
What is the structure of DNA?
A
A double helix, made up of two strands linked by their bases
4
Q
What are the complimentary bases?
A
- Adenine + Thymine
- Guanine + Cytosine
5
Q
What is a gene?
A
A section of DNA that codes for a protein
6
Q
What can happen to the protein if there is a problem with the gene?
A
- Be the wrong shape and not work properly
- May not be made at all
7
Q
What are proteins made from?
A
Amino Acids
8
Q
Describe the process of protein production
A
- The DNA makes a complimentary copy of itself (mRNA) which codes for a protein
- The mRNA travels to the ribosome and determines the order of the amino acids in order to make a proteim
9
Q
How is the shape of the protein determined?
A
The sequence of amino acids
10
Q
How is the sequence of amino acids determined?
A
The base sequence in the DNA
