Polynucleotides is a chemical way to refering to DNA or RNA. The backbone of a DNA or RNA is an alternating sequence of sugars and phosphates. If the chain is DNA the sugar is deoxyribonucleic acid. If the chain if RNA, the sugar is ribonucleic acid.
sugar and phosphate
Nucleic Acid
Nucleotides.
Nucleotides are composed of a nitrogenous base, a pentose sugar, and a phosphate group.
It is a lipid. It is not a protein since it is not a chain of amino acids; it is not a carbohydrate because it doesn't follow the formula CmH2nOn; and it is not a nucleic acid since it is not a chain of nucleotides.
3! = 6 different sequences =================
DNA polymerase III can add nucleotides only to a chain of nucleotides that is alreadypaired with the parent strands. Hence, DNA polymerasecannot link the first nucleotides in a newly synthesizedstrand. Instead, another enzyme, an RNA polymerasecalled primase, constructs an RNA primer, a sequence ofabout 10 RNA nucleotides complementary to the parentDNA template. DNA polymerase III recognizes the primerand adds DNA nucleotides to it to construct the new DNAstrands. The RNA nucleotides in the primers are then replacedby DNA nucleotides.
Very long strings of many simple molecules linked to one another.
nucleotides
an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
A DNA molecule is composed of long chains of DNA nucleotides.
Three nucleotides are required for an amino acid. These nucleotides are an amine, carbolic acid, and a side chain specific to the amino acid.
Nucleotides.
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
Nucleotides are composed of a nitrogenous base, a pentose sugar, and a phosphate group.
A macromolecule is formed from many molecules linked together in a chain and of course has a higher molecular mass.
Polysaccharide constitutes a long chain of simple sugars. The genetic information is coded in DNA by the sequence of the nucleotides.
Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.
It is a lipid. It is not a protein since it is not a chain of amino acids; it is not a carbohydrate because it doesn't follow the formula CmH2nOn; and it is not a nucleic acid since it is not a chain of nucleotides.
