Study Notes
Genetic Code and Structure
- The genetic code is a triplet code, consisting of three nucleotides.
- A prokaryotic chromosome is a single circular DNA molecule.
- RNA is synthesized in the 5' to 3' direction.
- The sugar-phosphate backbone of DNA is composed of 5-carbon sugars (ribose) and phosphate groups.
Transcription and Translation
- Transcription is the process of creating mRNA from DNA.
- The POLY merase enzyme binds to the start of transcription.
- The open reading frame (ORF) is the sequence of DNA that codes for a protein.
- The sequence of mRNA is complementary to the template DNA strand.
Gene Expression
- Genotype refers to the genetic makeup of an organism, including both coding and non-coding regions.
- Phenotype refers to the physical expression of the genes, resulting in a protein product.
- The flow of genetic information is from DNA to RNA to protein (Central Dogma of Life).
Gene Transfer
- Vertical gene transfer is the transmission of genetic information from one generation to the next through DNA replication and binary fission.
- Horizontal gene transfer is the transfer of genetic information between organisms other than by vertical inheritance.
Prokaryotic Chromosome
- The genetic map of a prokaryotic chromosome shows the location of genes and their relationship to each other.
- Mutations can occur in DNA sequences, resulting in changes to the genetic code.
- The wildtype is the normal or non-mutated DNA sequence.
Miscellaneous
- Genome refers to all the genetic information in an organism.
- Genes are the basic units of heredity, carrying information from one generation to the next.
- Genetic information is encoded in DNA, which is composed of coding and non-coding regions.
