Topic 2

?
Mononucleotide
A molecule consisting of a phosphate group, pentose sugar and nitrogenous base that forms a polynucleotide chain, joined by phosphodiester bonds, to form DNA.
1 of 8
Complementary base pairing
Adenine pairs with thymine, cytosine pairs with guanine.
2 of 8
Semi-conservative replication
The nature of DNA replication where a new synthesised DNA molecule contains one parent strand and one new strand.
3 of 8
Codon
Three bases on DNA or RNA.
4 of 8
Messenger RNA (mRNA)
A copy of a section of DNA that carries information from the DNA in the nucleus out into the cytoplasm.

Transfer RNA (tRNA)
Picks up particular amino acids from the cytoplasm.
