Compare and Contrast-Structure and Functions

 Genes

  • Introns and exons
  • Groups of base-pairs
  • Stores coding information
  • Flanking regions- 5' flanking region, 3' flanking region, coding region
  • Located in DNA

Chromosomes

  • In chromatin form (usually)
  • Made up of DNA
  • Genetic information(DNA)
  • Certain number of pairings for different types of species (humans=23 pairings)
  • Located in nucleus

 DNA

  • Twisted ladder
  • Base-pairings
  • Double-helix(sugar-phosphate)
  • Stores and codes  information
  • Located inside chromosomes

 Similarities

  • All have to do with traits and characteristics of different organisms.
  •  All are located in eachother; genes inside DNA, DNA inside chromosomes, chromosomes inside nucleus.

Explained Differences in Functions and Structure of DNA, mRNA, & tRNA

  • mRNA is a messenger RNA meaning it carries information from DNA to different parts of the cell.
  • tRNA is a transfer RNA meaning it transfers the amino acids to the ribosome according to the mRNA's coded messages.
  • DNA is what stores, copies, and trasmits genetic information in a cell.
