The structure of DNA is described as a double helix. That is made up of three subunits - a phosphate, deoxyrbiose sugar and a base.
1 of 8
What bases are complementary?
Adenine (A) always pairs with Thymine (T) and Guanine (G) always pairs with Cytosine (C)
2 of 8
Explain how the sequences of bases code for amino acids.
The sequence of the bases codes for the order of the amino acids. A group of 3 bases - known as a triplet - codes for one amino acid.
3 of 8
What is a gene?
A gene is the sequence of bases on DNA that codes for a protein.
4 of 8
What is the genetic code?
The code formed by the order of the bases in DNA that determines an organism's characteristics.
5 of 8
What is mRNA?
mRNA is a messenger that is a copy of DNA which attaches to the ribosome and uses its instructions to assemble amino acids in the correct order for a specific protein.
6 of 8
Where does mRNA go from and where does it go to?
mRNA goes from the nucleus to the cytoplasm.
7 of 8
Where are proteins assembled?
Proteins are assembled at ribosomes in the cytoplasm of the cell.
