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.
