Study Notes
Heredity and Nucleic Acids
- Heredity is the passing of traits or characteristics from parents to offspring through genes.
Chromosomes
- Chromosomes are thread-like structures made up of DNA and proteins that carry genetic information.
Nucleic Acids
- Nucleic acids are biomolecules that contain the genetic instructions used in the development and function of all living organisms.
- There are two main types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
- Proteins are not a type of nucleic acid.
DNA
- DNA is responsible for storing and transmitting genetic information from one generation to the next.
- DNA is present in the cells of all living organisms, specifically in the chromosomes of the cell nucleus.
- The main function of DNA is to provide a blueprint for the development and function of an organism.
RNA
- RNA plays a crucial role in the transmission of hereditary information by carrying genetic information from DNA to the ribosomes, where proteins are synthesized.
Characteristics of Nucleic Acids
- Nucleic acids are capable of replication and transmission of genetic information.
- They are resistant to degradation and can withstand high temperatures.
- They are sensitive to ultraviolet (UV) light.
- Nucleic acids are not capable of catalyzing chemical reactions.
