What do we understand by the term antisense technology
Antisense technology is a biotechnology method used to control or block the production of a specific protein in a cell by targeting its genetic message.
Simple idea
Cells make proteins using mRNA (messenger RNA) as instructions copied from DNA.
Antisense technology introduces a short strand of nucleic acid (DNA or RNA) that is complementary to that mRNA.
When the antisense strand binds to the mRNA:
-
The mRNA gets blocked or destroyed
-
The protein cannot be produced
Why it’s called “antisense”
-
The normal mRNA sequence is called the “sense” strand
-
The complementary blocking strand is the “antisense” strand
How it works (basic steps)
-
Identify the gene/protein to suppress.
-
Design an antisense RNA/DNA sequence that matches the mRNA.
-
Introduce it into the cell.
-
Antisense binds to mRNA.
-
Translation is stopped → protein production decreases or stops.
Uses / Applications

One-line definition
Antisense technology is a gene-silencing technique that uses a complementary nucleic acid strand to bind mRNA and prevent a specific protein from being produced.
