Organic molecules that consist of a 5 carbon sugar (ribose in the case of RNA, and deoxyribose in the case of DNA), a phosphate group and a nitrogenous base; nucleotides are the building blocks of nucleic acids (DNA & RNA).
A nucleotide building block of DNA and RNA, adenine is classified as a purine and complements thymine (T) in DNA and uracil (U) in RNA.
A nucleotide building block of DNA, thymine is classified as a pyrimidine and complements adenine (A) in DNA; thymine is not found in RNA.
A nucleotide building block of DNA and RNA, guanine is classified as a purine and complements cytosine (C) in DNA and RNA.
A nucleotide building block of DNA and RNA, it is classified as a pyrimidine and complements guanine (G) in DNA and RNA.
The way that nucleotides interact with one another, A bonds with T and C bonds with G in DNA, while C bonds with G and A bonds with U (uracil) in RNA. The sequence of base pairs creates the genetic code that is transcribed and translated into proteins.
A segment of DNA that codes for a specific protein, genes are a sequence of nucleotides.
The arrangement of nucleotides that form genes in strands of DNA.
The shape of the DNA molecule, often times is referred to as the “twisted ladder” and is the title to the book about Watson & Crick's discovery of DNA's structure.
