The vector for dengue virus is: MCQ with Answer and Explanation

Explanation:
Gel electrophoresis is a widely used technique to separate charged molecules, primarily DNA, RNA, or proteins, in an electric field through a gel matrix (usually agarose for DNA). DNA fragments are separated based on their size (length in base pairs). Smaller fragments move faster and further through the gel than larger ones. The separated DNA bands are visualized using ethidium bromide and UV light.

Explanation:
GMOs are organisms whose genetic material has been modified through recombinant DNA technology, introducing or deleting specific genes. Selective breeding and cross-pollination are traditional methods that do not directly manipulate DNA. Cloning produces genetically identical copies without necessarily altering the genome. Examples: Bt cotton, Golden rice.

Explanation:
In botanical classification, the term 'Division' corresponds to 'Phylum' in zoological classification. For example, flowering plants are in the Division Magnoliophyta (or Angiosperms), while animals are in Phyla like Chordata. The hierarchy is Kingdom → Division/Phylum → Class → Order → Family → Genus → Species. This terminological difference is a key point in taxonomy.
