Study Notes
DNA vs RNA
- DNA is found in the cell nucleus
- DNA stores and transfers genetic information
- DNA is passed from existing cells to new cells during cell division
- RNA occurs in all parts of a cell
- RNA's primary function is protein synthesis
Purines vs Pyrimidines
- Five nitrogenous bases exist
- Purines are double ring structures (Guanine, Adenine)
- Pyrimidines are single ring structures (Cytosine, Thymine, Uracil)
- Guanine and Adenine are found in both DNA and RNA
- Cytosine is found in both DNA and RNA
- Thymine is found in DNA
- Uracil is found in RNA
Nucleoside Formation
- Nitrogenous base is connected to C1 of the sugar
- C2 of the sugar is differentiated by H or OH
- C5 is where the phosphate is attached
Structural Characteristics of DNA
- DNA consists of two anti-parallel polynucleotides
- One strand runs 5' to 3', the other runs 3' to 5'
- Sugar-phosphate backbone is on the outside
- Hydrophobic bases are on the inside
Base Pairing
- A pyrimidine pairs with a purine
- A pairs with T (two hydrogen bonds)
- G pairs with C (three hydrogen bonds)
DNA Replication
- Helicase unwinds the DNA helix
- Primase adds RNA primers
- Polymerase III copies the DNA strands
- Polymerase I replaces RNA primers with DNA nucleotides
- Ligase seals the DNA segments
Transcription
- Process of copying DNA segment to RNA
- DNA segments that produce messenger RNA (mRNA) encode proteins
Types of RNA
- Ribosomal RNA (rRNA)
- Most abundant
- Structural component of ribosomes
- Transfer RNA (tRNA)
- Second most abundant
- Carries amino acids to ribosomes
- Messenger RNA (mRNA)
- Carries information to ribosomes, specifying amino acid sequence
- Only type of RNA that is translated
Translation
- mRNA is translated into protein
- Codon: a sequence of three mRNA nucleotides that codes for an amino acid
- The order of codons determines the order of amino acids
- Start codon: AUG (methionine)
- Stop codons: UAA, UAG, UGA
Central Dogma
- Replication: DNA makes identical copies of DNA
- Transcription: DNA makes RNA
- Translation: RNA makes proteins
Mutations
- Changes in the DNA sequence at a particular gene locus
- Can be harmful, beneficial, or neutral
Point Mutations
- Silent mutation: no change in protein activity
- Missense mutation: one amino acid substituted
- Nonsense mutation: premature stop codon, shortened protein
- Frameshift mutation: addition or deletion of DNA bases, altered reading frame
Polymerase Chain Reaction (PCR)
- Technique to make many copies of a specific DNA region
- Steps: denaturation, annealing, extension
Lipids
- Insoluble or sparingly soluble in water
- Soluble in nonpolar organic solvents
- Types of lipids include triacylglycerols, phospholipids, sphingolipids, waxes, steroids, and terpenes
- Classified by solubility
Fatty Acids
- Members of carboxylic acids
- Hydrocarbon chain with a terminal carboxyl group (COOH)
- Saturated fatty acids: solid at room temperature
- Unsaturated fatty acids: liquid at room temperature
Prostaglandins
- c20 fatty-acid derivatives
- Involved in raising body temperature, inhibiting gastric juices, increasing mucus secretion.
Thormboxanes
- c20 fatty-acid derivatives
- Promote platelet aggregation (blood clotting)
Leukotrienes
- c20 fatty-acid derivatives
- Promote inflammation
Higher Unsaturated Fatty Acids (UFAs)
- HUFA: Polyunsaturated fatty acids with greater than 20 carbon atoms
- Essential for proper neural and visual function
Essential Fatty Acids (EFAs)
- Cannot be synthesized by animals.
- Must be obtained from diet
- EFA n-6 and n-3
Cholesterol
- Major steroid in the body
- Precursor to bile salts, steroid hormones
Protein Denaturation
- Loss of a protein's natural shape and function
- Factors that cause denaturation:
- Heat
- Alcohol
- Acids
- Inorganic chemicals
- Organic chemicals
- Alkalis
Chemical Reactions of Triacylglycerols
- Hydrolysis: breakdown with water (lipases)
- Saponification: breakdown with base (produces soap)
Protein Structural Organization
- Primary structure: linear sequence of amino acids
- Secondary structure: local folding patterns (alpha helix, beta sheet)
- Tertiary structure: overall 3D shape
- Quaternary structure: interactions between multiple polypeptide chains
Peptide Bonds
- Bonds that link amino acids in a polypeptide chain
- Formed by condensation reaction (loss of water)
Enzymes
- Protein catalysts that accelerate chemical reactions
- Types:
- Oxidoreductases
- Transferases
- Hydrolases
- Lyases
- Isomerases
- Ligases
Enzyme Activity Factors
- Temperature
- pH
- Substrate Concentration
- Enzyme Concentration
- Inhibitors/Activators
Isoelectric Point (pI)
- pH at which an amino acid has no net charge (zwitterion)
Stereochemistry of Amino Acids
- Chiral amino acids (except glycine) exist as L or D isomers
- Proteins generally utilize L-amino acids
