double helix
Shape of DNA molecule due to coiling of the two sugar-phosphate backbone strands into a right handed spiral configuration
1 of 12
Monomer
molecule that when repeated makes up a polymer
2 of 12
Nucleotide
Molecule consisting of a five carbon sugar, a phosphate group and a nitrogenouse base
3 of 12
polynucleotide
large molecule containing many nucleotides
4 of 12
DNA polymerase
enzyme that catalyses formation of DNA from activated deoxyribose nucleotides using single stranded DNA as a template
5 of 12
Helicase
Enzyme that catalyses the breaking of hydrogen bonds between the nitrogenouse bases in a DNA molecule
6 of 12
semi-conservative replication
how DNA replicates, resulting in two new molecules each of which contain one old strand and one new strand.
7 of 12
gene
a length of DNA that codes for polypeptides or for a length of RNA that is regulating gene expression
8 of 12
polypeptide
a polymer made of many amino acid units joined together by peptide bonds
9 of 12
Protien
a large polypeptide of a 100 or more amino acids.
10 of 12
Transcription
the process of making messenger RNA from a DNA template
11 of 12
translation
formation of a protein, at ribosomes by assembling amino acids into a particular sequence acording to the coded instructions carried from DNA to the ribosomes by mRNA
