Nucleic Acids to Amino Acids: DNA Specifies Protein. Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. ... It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C).

Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.

What is an amino acid? An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid.

Adenine pairs with thymine with 2 hydrogen bonds. Guanine pairs with cytosine with 3 hydrogen bonds. This creates a difference in strength between the two sets of Watson and Crick bases.

Bottom line is that a codon is a piece of genetic code, while an amino acid is a single chemical compound, of which proteins are comprised. The codons serve as signals for specific amino acids. That is how they are related.

Answer and Explanation: Amino acids do not contain phosphorus. ... They also contain hydrogen and oxygen, and the amino acids that make up proteins are the molecules that contain nitrogen. The only organic molecules that contains phosphorus are nucleic acids, which are DNA and RNA.

Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group (Figure 1). The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.

These nitrogenous bases are Adenine (A), Cytosine (C) and Guanine (G) which are found in both RNA and DNA and then Thymine (T) which is only found in DNA and Uracil (U), which takes the place of Thymine in RNA.

Terms in this set (48) Amino acid Definition: An amino acid is a carboxylic acid with an amino group and the building block of proteins. ... contains 2 or more NH2 groups or nitrogen atoms (base ).

Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group. The R group determines the characteristics (size, polarity, and pH) for each type of amino acid. ... A chain of amino acids is a polypeptide.

Cytosine pairs with Guanine, and Adenine pairs with Thymine. This means, that if there are 45 cytosines, there must be 45 guanines.

The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); guanine (G) pairs with cytosine (C).

Guanine and cytosine make up a nitrogenous base pair because their available hydrogen bond donors and hydrogen bond acceptors pair with each other in space. Guanine and cytosine are said to be complementary to each other. This is shown in the image below, with hydrogen bonds illustrated by dotted lines.

Glycine is an organic compound. it is one of the 20 amino acids commonly found in animal proyien. Glycine is not essential to human diet since it is synthesized in the body. Glycine is an organic compound that contains 2 carbon atoms, 5 hydrogen atoms, 1 nitrogen atom, and 2 oxygen atoms.

Are adenine, guanine, cytosine and thymine isomers of one another? ... No, Adenine and Guanine are purines, bicyclic molecules larger than Cytosine and Thymine, which are monocyclic pyrimidines.
