When one bacterium transfers its genetic material through direct contact to others. The bacterium transfers its genetic material called <u>donor cell</u> and one serves it called <u>recipient cell.</u>

There are mainly four steps in this process-

1. Connecting sex pilus to recipient cell by donor cell.

2. The Fusion of cell membranes and transfer of single strand of DNA to the recipient cell.

3. Each bacterium cell makes a complementary DNA strand.

A glycosidic linkage is analogous to_________ in proteins
luda_lava [24]

Answer: Peptide bond

Explanation:

Polysacharride are monomers of carbohydrates linked together by glycosidic bonds to form long chains, also proteins are polymers of amino acids linked together by peptide bonds.

Linear chains of carbohydrates are linked together by glycosidic alpha-1,4- glycosidic linkages(between the OH group of the first carbon if the 1st monomer and the OH group of the 4th carbon of the second monomer. The branched point are linked by alpha-1,6-linkages.

In proteins the alpha carboxyl group of one amino acid react with alpha amino group of another amino acid to form a peptide bond or CO-NH bridge. Proteins are made by polymerization of amino acids through peptide bonds.
