Study Notes
Genetic Material
- DNA is the primary genetic material for the majority of organisms.
RNA as Genetic Material
- RNA acts as the genetic material in some organisms, such as certain viruses.
RNA Roles
- Apart from being a messenger, RNA has additional roles, including acting as a genetic material and catalyst.
Nucleic Acids
- Nucleic acids are polymers of nucleotides.
Molecular Basis of Inheritance
- Chapter [insert chapter number] in the book addresses the molecular basis of inheritance.
Nucleotide Components
- A nucleotide is composed of three components: a sugar molecule, a phosphate group, and a nitrogenous base.
Organism Characteristics
- An organism's characteristic can be defined by the length of its DNA.
Polynucleotide Chain
- The backbone of a polynucleotide chain is formed by sugar molecules and phosphate groups.
Nitrogenous Bases
- Thymine is a nitrogenous base present in DNA but not in RNA.
Polynucleotide Chain End
- The 5' end of a polynucleotide chain contains a free phosphate moiety, characterizing it as a distinct end.
