DNA Structure
A molecule composed of genetic (hereditary) material
DNA
the process of copying one DNA double helix into two identical double helices
Replication
Making the mRNA
Transcription
making the protein
Translation
These can be caused by mutagens, such as Radiation, X-rays, UV radiation, certain organic chemicals
Mutagens
A complex containing phosphate, a pentose sugar, and a nitrogen base.
Nucleotide
This enzyme "unzips" and unwinds the double-stranded DNA
DNA helicase
Transcription occurs here
in the nucleus
translation occurs here
in the cytoplasm
When a cancer cell travels to a new part of the body and invades new tissue it is called______
Metastasis
Adenine, Thymine, Cytosine, Guanine
nitrogen-containing bases in DNA
a term meaning new double helix has one original strand and one new strand
semi conservative
During processing, these are removed from the primary RNA
Introns
Utilises the mRna, tRna and rRna
Translation
One or more nucleotides are either inserted or deleted from DNA
Frameshift mutations
This bond holds the base pairs together on the double helix.
hydrogen bond
This enzyme matches complementary bases to the old strand on the DNA
DNA Polymerase
DNA helix is unzipped using what enzyme so complementary RNA bases can be matched
helicase
tRNA transports these to the ribosomes for protein synthesis
Amino Acids
Most cancers start as abnormal cell growth and do not continue to grow. THey are called __________
Benign
some cancers provide blood vessels that bring blood and nutrients and oxygen to the tumour, otherwise called ______________
angiogenesis
