Nucleobases Flashcards
Functions of Nucleobases
Building blocks of DNA & RNA, Energy Transfer: ATP
Pyrimidines
Cytosine (C), Adenine (A), Guanine (G)
Purines
Uracil (RNA), Thymine (DNA)
Nucleoside
Nitrogenous Base + Sugar
Nucleotide
Nitrogenous Base + Sugar + Phosphate Group
How do Nucleotides relate to ATP?
ATP is a nucleotide !
Adenine + Ribose + Triphosphate
How does DNA form?
- Nucleotides are connected to make a DNA strand
- Two strands of DNA are bonded together through hydrogen bonding of nucleotides (strands are vertical)
- The hydrogen binding causes double helix shape to form.
The Central Dogma & How to Relates to Formation of (m)RNA
Transcription: (m)RNA is synthesized from DNA by an enzyme called RNA polymerase by using one DNA strand as a template.
DNA —> (m)RNA
Translation: mRNA acts as a code for protein. Codon (3 Nucleotide) are bonded with an amino acid by tRNA. This continues until Polypeptide chain is made!
(m)RNA —> Protein
