RNA Transcription
Created @February 19, 2025 7:56 PM
Class Cells to Systems
Nucleotide Functions
ATP production for metabolism
NAD+ as enzyme cofactor
cAMP signal transduction
Nucleic Acid Functions
Stores genetic info
Transmitting gene info as mRNA
Processing gene info as ribosomes
Using tRNA and rRNA as protein synthesis
Expression regulation as siRNA and miRNA
Subunits are linked by phosphodiester bonds
DNA Helical Structure
Consists of two nucleotide chains coiling around
RNA Transcription 1
, Sugar phosphate are backbones of two spiral strands externally of the
helix
Nitrogenous bases extend into centre of helix
Hydrogen Bonding
Non- covalent attraction helps maintain double helix
Adenine forms 2 H bonds w/ Thymine
Cytosine forms 3 H bonds w/ guanine
H bonding pattern= Base Pairing
4-7 Regulates gene pathway
RNA Structure
Single stranded
Can’t form Beta- form helix
Becomes helical once alpha form takes place.
Transitions from deep/ narrow groove to wide minor groove
Secondary structure in rRNA/tRNA could be mRNA
RNA Molecules are either hairpin structures or stem loops
mRNA contains instructions for protein construction
Ribosomal RNA( rRNA)
RNA Transcription 2
