DNA - Deoxyribonucleic Flashcards
Who was the structure of DNA discovered by
James Watson and Francis Crick
What units is DNA made up of
Nucleotides
What are Nucleotides arranged into
Polynucleotides
What are the 3 parts of nucleotide
Phosphate, Sugar and deoxyribose
How are the 2 bases joined together (All tits go Saggy)
Adenine with Thymine and Guanine with Cytosine
Give 2 similarities between DNA and RNA
Are made of nucleotides and are found in the nucleus
Give 2 differences between DNA and RNA
DNA is double sided, RNA is single sided and DNA has T while RNA has U
What is protein synthesis
Production of protein (Transcription and Translation)
What is Transcription
Enzymes unwind DNA and complimentary RNA bonds with the DNA base strands
What is Translation
mRNA attaches to ribosome and attaches complimentary sections of RNA which creates protein
What is the first step in preparing a DNA profile
Cells are broken down to release their DNA
What is the second step in preparing a DNA profile
The isolated DNA is cut into fragments using special restriction enzymes
What is the third step in preparing a DNA profile
The fragments are seperated
What is the fourth step in preparing a DNA profile
Comparison of patterns
What are the 2 base types
Pyrimidine and Purine
