Explanation:

Only statement 1st is correct.

About Nanopore Technology

• Nanopore technology refers to nano-scale holes embedded in a thin membrane structure to detect the potential change when charged biological molecules smaller than nanopores pass through the hole.

• It has the potential to sense and analyze single-molecule amino acids, DNA, RNA, etc.

• It is a cutting-edge method for sequencing DNA and RNA by detecting changes in electrical conductivity as molecules pass through a nanopore.

• In contrast to other sequencing technologies, nanopore-based sequencing is cheaper, very easy to use, does not require much computational and lab infrastructure, and only needs a small amount of DNA in a test sample.

• It is the only sequencing technology that offers real-time analysis in fully scalable formats, from pocket to population scale, that can analyze native DNA or RNA and sequence any length of fragment to achieve short to ultra-long read lengths.

• It can also undertake targeted sequencing with a focus on specific genes/regions.

Hence option 1st is correct.
