Study Notes
Sources of Nucleic Acid for Extraction
- Blood, tissues, and cells can be used as sources of nucleic acid for extraction
- Viruses, bacteria, and other microorganisms can also be used as sources of nucleic acid for extraction
Types of Nucleic Acid
- Both DNA and RNA can be isolated from samples
- Mitochondrial DNA and chloroplast DNA can be isolated from organelles that contain their own genetic material
- Extra-nuclear DNA, also known as cytoplasmic DNA, is found outside the main genome in certain organelles like mitochondria and chloroplasts
Purpose of Extracting Pure Nucleic Acids
- The primary purpose of obtaining pure nucleic acids is for use in various molecular techniques
- Pure nucleic acids can be used for techniques such as PCR, DNA sequencing, and gene cloning
Organelles with Genetic Material
- Mitochondria and chloroplasts contain their own genetic material, DNA
Molecular Techniques
- The first step for all molecular techniques is the extraction of pure nucleic acids
- Pure nucleic acids can be used for techniques such as PCR, DNA sequencing, and gene cloning
Exclusion
- Saliva is not a potential source of nucleic acid for extraction
