An amino acid is considered to be at its isoelectric point when the positive charges on the molecule exactly balance its negative charges. At this point, the amino acid carries no net charge and is therefore immobile in an electric field. Isoelectric points of amino acids widely vary accoriding to their side chains and polarity characteristics.

What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.
How does the process of translation convert information?
From a nucleic acid code to an amino acid code
What is a beta-amino acid?
A beta-amino acid is an amino acid which has the amino and carboxylic functional groups attached to adjacent carbon atoms.
In the genetic code a group of three nitrogen bases codes for a?
amino acid
If a food does not contain the necessary amounts of a certain amino acid to meet a body need that amino acid is called what?
limiting amino acid
How do you calculate the isoelectric point of all 20 amino acid?
by isoelectric focusing appratus
What is meant by isoelectronic point of protein?
Isoelectric point of a protein or amino acid is defined as the pH value at which the molecule has equalpositive charges on protonized basic (amino) groups as negative charges on protolized acid (carbonic) groups, so the net charge is neutral (zero).
Which group of atoms in an amino acid gives it its particular properties?
Their functional or "R" group of the individual amino acid.
Is trytophan an acid or a base?
Like any other amino acid, tryptophan possesses both acidic and basic characteristics, referred to as amphoteric substances. It acts as an acid at pH below 5.89 and as a base at pH above 5.89. 5.89 here is the isoelectric point of tryptophan, a pH value where its overall charge is zero and wherein it neither acts as an acid, nor as a base.

What amino acid is technically not an amino acid?
proline is not an amino acid it is an imino acid
What type of mutations involve one amino acid?
a point mutation
What is the isoelectric point of HBsAg?
4.5 to 5.5 . its acidic.
What impact could a point mutation do?
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.
Each codon calls for a specific?
amino acid
