DNA and RNA
DNA
2 DNA polynucleotides join by hydrogen bonds between bases
A joins to T and G joins to C. there is an equal amount f these in there
2 hydrogen bonds join A and T
3 hydrogen bonds join G and C
antiparallel polynucleotides twist to make DNA double-helixs.
nucleotides joining together
CONDENSATION REACTION
happens between a phosphate group and a sugar
forms PHOSPHODIESTER BONDS
consist of a phoshate group and 2 ester bonds
the chain is called a SUGAR-PHOSPHATE BACKBONE
RNA
a single polynucleotide is used to make RNA
they are much shorter chains
nucleotides
make of phosphate group, pentose sugar and base
DNA bases are A, T, C, G
DNA pentose sugar is deoxyribose
RNA bases are A, T, C, G
RNA pentose sugar is ribose
they both carry information
they both are made of nucleotides
they both are found in all living things
