Study Notes
DNA Structure and Components
- Adenine, Guanine (G), Cytosine (C), and Thymine (T) are the four nitrogenous bases in DNA.
- Cytosine (C) forms hydrogen bonds specifically with Guanine (G).
- The sequence of nucleotides in DNA carries the genetic information of an organism.
- Chargaff's rules indicate that the number of purine bases (A and G) equals the number of pyrimidine bases (C and T) in DNA.
Genetic Function and Characteristics
- DNA serves as the genetic material for all organisms.
- Pyrimidine bases (C and T) have a single-ring structure.
- Purine bases (A and G) have a double-ring structure.
- DNA and RNA are the two main types of nucleic acids found in living cells.
DNA Organization and Processes
- DNA supercoils to form structures known as chromosomes, which organize genetic material for cell division.
- New messenger RNA (mRNA) is synthesized through the process of transcription, where DNA serves as a template.
