Topic 2.6: DNA / RNA Structure Flashcards
What are nucleic acids
the genetic material of the cell and are composed of recurring monomeric units called nucleotides
What are nucleotides composed of
5-carbon pentose sugar
Phosphate group
Nitrogenous base
What is DNA
a more stable double stranded form that stores the genetic blueprint for cells
What is RNA
a more versatile single stranded form that transfers the genetic information for decoding
In DNA, which nitrogenous bases are paired together
Adenine pairs with thymine via two hydrogen bonds
Guanine pairs with Cytosine via three hydrogen bonds
What is the arrangement of DNA
a double helix
The structural organization of DNA molecule was correctly proposed by who
James Watson and Francis Crick
Who was Rosalind Franklin
a scientist who correctly identified the DNA molecule through X-ray crystallography.
