What is the length of tRNA?
Transfer RNA molecules are small, each with a chain length of 75 to 90 nucleotides.
What is alpha carbon in amino acids?
All the amino acids have an amino group (-NH2) and a carboxyl group ( COOH) attached to the same carbon atom, also known as alpha carbon.
What is the general formula of amino acids?
They have the general formula as R (amino group) H2N-CCOOH (carboxyl group) alpha carbon.
How głycylalanine is formed? or How peptide bond is formed?
Glycylalanine is formed when amino acid glycine combines with amino acid alanine. The linkage between the hydroxyl group of carboxyl group of one amino acid and the hydrogen’ of amino group of another amino acid release H2O and C – N link to form peptide bond. Thus a dipeptide, glycylalanine, is formed.
How the specific properties of a protein are determined?
The specific properties of each protein are determined by the number and the specific sequence of amino acids in a molecule, and also depend upon the shape which the molecule assumes as the chain folds into its final, compact form
What did F. Sanger conclude about insulin?
Sanger concluded that insulin is composed of 51 amino acids in two chains. One of the chains had 21 amino acids and the other had 30. amino acids and they were held together by disulphide bridges
What is the composition of hemoglobin? or How many amino acid chains are present in hemoglobin? Also give number of amino acids in each chain.
Haemoglobin is composed of four chains two alpha and two beta chains. Each alpha chain contains 141 amino acids, while each beta chain contains 146 amino acids.
