Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
Answer:
The given blank can be filled with interferons.
Explanation:
The signaling molecules or the proteins that get discharged by the cell infected by the virus to protect the adjacent cells by stimulating a safeguarding defense mechanism are termed as interferons.
The mentioned proteins obstruct the proliferation of viruses and thus helps the cell in getting rid of the infection. These molecules also assist in stimulating the macrophages and the natural killer cells.
