A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first t
Vesna [10]

Answer:

a) 28 cases

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

<em>See the attached image for the genetic code.</em>

Phoenix [80]

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.

The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.

Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.
