Nucleic acids are made up of monomers known as…
Nucleotides
Which type of sugar do nucleotides contain?
pentose
Name the three components of a nucleotide:
(pentose) sugar
nitrogenous base
phosphate (group)
Are polynucleotides broken down via hydrolysis or condensation reactions?
hydrolysis
Nucleotides join together via …. bonds.
phosphodiester
What are phosphodiester bonds?
Strong covalent linkages that connect nucleotides to form the sugar-phosphate backbone of DNA and RNA.
Which nucleotide parts are involved in a phosphodiester bond?
phosphate and sugar
Which pentose sugar do DNA nucleotides contain?
deoxyribose
What bases do DNA nucleotides contain? DNA nucleotides may contain the bases adenine, thymine, cytosine or guanine.
adenine
thymine
cytosine
guanine
How many strands does a DNA molecule contain?
2- which is held together by hydrogen bonds between complementary nitrogenous bases (adenine pairs with thymine and cytosine pairs with gaunine).
Which nitrogenous bases are classed as purines?
Guanine and Adenine
Which nitrogenous bases do RNA nucleotides contain?
Uracil
Adenine
Cytosine
guanine
What sugar does RNA nucleotides contain?
Ribose
Which nucleic acid is single stranded?
RNA
True or False? RNA molecules are longer than DNA molecules.
False
Give 2 similarities and 2 differences between DNA and RNA.
Similarities:
Both contain Adenonine, Cytosine and Gaunine.
Both made up of nucleotides.
Differences:
RNA is shorter than DNA.
DNA is double stranded, RNA is single stranded.
