Study Notes
DNA and RNA Differences
- Deoxyribose is the type of sugar found in DNA, while ribose is found in RNA.
DNA Base Pairing
- Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C) in DNA.
Nucleic Acid Structure
- Phosphodiester bonds join nucleotides in a nucleic acid polymer, forming the backbone of DNA and RNA strands.
DNA Strand Directionality
- The directionality of a DNA strand is represented by the 5' to 3' ends, indicating the orientation of the sugar-phosphate backbone.
Protein Primary Structure
- The primary structure of a protein is the linear sequence of amino acids that make up the polypeptide chain.
Protein Secondary Structure
- Hydrogen bonds between the backbone atoms of the polypeptide chain are responsible for the secondary structure of proteins, forming alpha-helices and beta-sheets.
Amino Acid Sequence Determination
- The sequence of amino acids in a protein is determined by the genetic code present in an organism's DNA.
Protein Structure Influences
- Heat, pH, and salt concentration can denature proteins, disrupting their structure and function by breaking weak interactions.
Nucleic Acid Functions
- Nucleic acids, including DNA and RNA, are essential for storing and transmitting genetic information, as well as guiding protein synthesis.
ATP Function
- Adenosine triphosphate (ATP) acts as the primary energy currency in the cell, providing energy for various biochemical reactions.
Nucleic Acid Monomers
- The monomer of nucleic acids is the nucleotide, composed of a sugar, phosphate group, and a nitrogenous base.
NAD+ and FAD+ in Metabolism
- NAD+ (Nicotinamide adenine dinucleotide) and FAD+ (Flavin adenine dinucleotide) are coenzymes involved in redox reactions, crucial for energy production in cellular respiration.
