Hollow proteins used during bacterial conjugation (transfer of dna) are called: a. pili b. flagella c. mesosomes d. polysaccharides

The correct answer will be option A Pili .

Explanation:

Bacterial conjugation is the sexual mode of transfer of genetic material by direct contact between two bacterial cells.

This process is mediated by the formation of  bridge like connection between two cells by specialized cell surface structures in bacteria called F pili.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
