Structure
& Synthesis of DNA
Structure of RNA
“ single-stranded
molecule
“ less stable
than DNA:
“ Thymine is
replaced by uracil
“ Sugar is
ribose instead of deoxyribose as in DNA
Synthesis of DNA
“ site of
protein synthesis is the:
cytoplasm
“ genetic
information contained in DNA must be transferred from nucleus to cytoplasm by RNA. Three types of RNA:
tRNA
mRNA
rRNA
transfer RNA
messenger RNA
ribosomal RNA
