Answer: Option (c) is the correct answer.

Explanation:

When there is transfer of electrons from one atom to another then it results in the formation of ionic bond.

This bond formation takes place between a metal and a non-metal.

Mg being a cation has excess of electrons and Cl being an anion has deficiency of electrons. Therefore, in order to attain stability there will be transfer of electrons between Mg and Cl.

Thus, out of the given options Mg and Cl will form an ionic bond

The atoms of Mg (Magnesium) and Cl (Chlorine) will form an ionic bond. Ionic bond is basically formed by the sharing of electrons. Magnesium being a metal has two electrons in its outermost shell which Mg can readily loose to attain stability, chlorine on the other hand has seven electrons in the outermost shell so it can accept one electron to attain stability. So, both Mg Cl can form ionic bond with each other so form a stable compound MgCl2.

Answer:

Agrobacterium tumefaciens is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.

Explanation:

It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.

There are 3 types of bacteria that form tumor in different plant ares.

Agrobacterium rhizogenes, Agrobacterium tumefaciens strains contain either Ti or Ri plasmid but Agrobacterium vitis contain only Ti plasmid which are virulent.

The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.

Which of the following is NOT a component of a nucleotide?

Paha777 [63]

Answer:

Option D.

Explanation:

The above answer given is incorrect. Nucleotides consist of a phosphate group attached to a pentose sugar, with 5 carbons, (deoxyribose sugar in the case of DNA) and the pentose sugar is also attached to a nitrogenous base. DNA is incorrect as nucleotides are the building block of DNA hence DNA is NOT a component of nucleotides.
