Nucleic Acids Flashcards
make up nucleic acids
nucleotides
3 components of nucleotide
phosphate
5 carbon sugar
nitrogenous base
example of 5 carbon sugar
ribose
5 carbon sugar present in DNA
deoxyribose
4 nitrogenous bases
adenine
guanine
cytosine
thymine
how are nucleotides linked together
by dehydration synthesis or polymerisation reactions betrween one sugar nucleotide and phosphate group of second nucleotide
forms the structural framework of nucleic acids, including DNA and RNA.
sugar phosphate backbone
DNA is composed of two strands arranged as a right handed ___
helix
orientation of the strands of a double helix
anti-parallel
what kind of bonds hold the two strands of double helix
hydrogen bonds
Guanine form hydrogen bonds with ___
cytosine
Adenine bonds with ___
thymine
RNA differs from DNA because it contains the sugar
ribose
nitrogenous base present in RNA
uracil
RNA is usually ___ and does not form ___
single stranded
helix
which is more stable
RNA/DNA
RNA
stores the information to construct a protein
DNA
regulates expression of information during protein synthesis
RNA
modified nucleotide that plays essential role in energy processing within cells
ATP
ATP is composed of
adenine
ribose
3 phosphate
bonds within ATP bonds are
high energy bonds
which phosphate group in ATP is removed when energy is needed
terminal phosphate
formed when terminal phosphate is removed in ATP
adenosine diphosphate
are biopolymers that carry information inside cells
