Answer:
not sure but I think it's option C.
Answer:
Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.
A target cell respond to a hormone because it bears receptors
<u>Primary structure of the protein </u>can be determined With the knowledge of the nucleotide sequence of a gene.
- Strings of amino acids make up proteins, and strings of nucleotides make up nucleic acids.
- A water molecule is removed during a biological process that links the carboxyl group of one amino acid to the amino group of a nearby amino acid to generate peptide bonds.
- The main structure of a protein is thought to be its linear amino acid sequence.
- A codon is a cluster of three mRNA nucleotides that codes for a particular amino acid.
- Each mRNA produces a protein that has a specific amino acid sequence corresponding to it. The start and stop of translation are indicated by two codons known as start and stop codons.
