Answer:
The correct answer will be option B (Interferons).
Explanation:
The innate immune response to viral infection begins with the recognition of pathogen which starts viral host response in organism.
After detection of viral infection cell produces type I interferon's, the protein molecule which interfere with the proliferation of viral cells.
Interferon's provide resistance to viral infection by :
1. Binding to IFN-α/β receptors which activate JAK/STAT pathway.
2. Production of enzymes which leads to the degradation of viral RNA.
3. Induction of ds-RNA-dependent kinase which inactivates the synthesis of proteins.
4. Binding to Natural killer cells which induces lytic activity, killing viral infected cells.
Thus, option B-interferon is the correct answer.
Answer:For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes). The diploid chromosome number varies by organism and ranges from 10 to 50 chromosomes per cell.
Explanation:
The best answer is "Chemistry, biology, and engineering"
Taking courses in chemistry, biology, and engineering would best prepare someone for a career in biotechnology, due to the intersection of of technology and biology, and the need for chemistry to better understand biological systems.
