If the strands separate then it'll be a mutation that can be good, bad, or indifferent. T doesn't connect with T again if the strand were to join together so there would be a mistake there.
Thymine denoted as "T".
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
DNA nucleotides are composed of the sugar deoxyribose, a phosphate group, and one of four nitrogen bases: adenine(A), thymine(T), guanine(G), cytosine(C).
A DNA molecule is composed of long chains of DNA nucleotides.
DNA and RNA are composed of nucleotides.
DNA polymerases are the enzymes responsible for joining DNA nucleotides together. In Prokaryotes - DNA Pol III is the enzyme which adds nucleotides to the new strand during DNA replication. DNA Pol I is responsible for replacing the primers with DNA nucleotides.
nucleotides- guanine, adenine, thymine, and cytosine
monomers,polymers=nucleotides
The monomers of DNA are called nucleotides, and the polymer is a polynucleotide.There are four different nucleotides in DNA called A, T, G, and C for the nitrogenous base sidegroup (adenine, thymine, guanine, and cytosine respectively) attached to the sugar-phosphate backbone (deoxyribose-phosphate) of a nucleotide. These nucleotides can be joined in any order, permitting the "spelling" of an unlimited number of different genetic "words".
DNA nucleotides. Note that adenine, thymine, cytosine and guanine are NOT nucleotides, but they are only the bases which make the nucleotides different.
Nucleotides are the monomer units that make up a DNA molecule. DNA nucleotides are composed of a deoxyribose sugar, a nitrogenous base, and a phosphate group.
A DNA nucleotide includes a phosphate, a deoxyribose sugar and a nitrogenous base. Only the nitrogenous base changes in the four different nucleotides. The four different bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
