What are the building blocks of proteins called? Nucleotides Monosaccharides Amino acids Fatty acids
DNA is a long polymer made from repeating units called nucleotides each of which is usually symbolized by a single letter: either A T C or G. Chargaff's rules state that DNA from any species of any organism should have a 1:1 protein stoichiometry ratio (base …

Nucleic acids are long-chain molecules which are of two kinds: DNA and RNA.Their building blocks are called nucleotides .. DNA is found in every cell. It contains the information needed to make all of the nucleic acids and all of the proteins .It is found joined up in a double helix.It is the substance of heredity and holds the information which life passes from generation to generation.
Peptides (from Greek language πεπτός peptós "digested"; derived from πέσσειν péssein "to digest") are short chains of between two and fifty amino acids linked by peptide bonds. Chains of fewer than ten or fifteen amino acids are called oligopeptides and include dipeptides tripeptides and tetrapeptides.. A polypeptide is a longer continuous unbranched peptide chain of up ...
According to Melvin Calvin certain reactions of condensation-dehydration of amino acids and nucleotides in individual blocks of peptides and nucleic acids can take place in the primary hydrosphere with pH 9–11 at a later evolutionary stage. Some of these compounds like hydrocyanic acid (HCN) have been proven in the experiments of Miller.
Nicotinamide adenine dinucleotide (NAD) is a cofactor central to metabolism. Found in all living cells NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide.NAD exists ...
