nucleic acids
two types of nucleic acids
DNA and RNA
the three components covenltly bonded together
a phosphate group
a sugar with 5 carbon atoms
a nitrogen base
DNA
contains genetic information
RNA
the messanger
Key features of DNA
double stranded
contains deoxyibose
contains A G T and C
located in the nucleus
made through replacation
key features of RNA
single stranded
contains ribose
contains A G U and C
can be in the nucleus or cytoplasm
mRNA is made through the process of transcription
Nitrogenous bases for DNA
cytosine and guanine
adenine and thymine
nitrogenous bases of RNA
cytosine and guanine
adenine and uracil
how are DNA and RNA put together
a double helix and when unwound looks like a ladder
the sides of the ladder are made up of alternating phosphate and sugar molecules
the rungs are the nitrogenous bases held togerther by hydrogen bonds
