Choose the correct statement

a. Hexokinases IV remains sequesters in the nucleus in case of high F-6-P and high ATP

b. Hexokinases IV remains sequesters in the cytoplasm in case of high F-6-P and high ATP

c. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is not ATP4- but the MgATP2- complex.

d. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.

Q. Statement I: In the cybrid approach, iodoacetate is used to inactivate the nuclei of the recipient strain (Parent A). 

Statement II: Irradiation is used to inactivate the nuclei of the donor strain (Parent B) to ensure only its cytoplasm is transferred.

Q. Statement I: In the fusion product described, the mitochondria are always derived from the donor strain (Parent B).

 Statement II: The chloroplasts in the resulting regenerants must always come from the recipient strain (Parent A)

Q. Statement I: Fusing tomato protoplasts with irradiated Solanum acaule protoplasts produced plants that were morphologically identical to Solanum acaule. 

Statement II: The resulting tomato regenerants exhibited Cytoplasmic Male Sterility (CMS), which was inherited maternally.

Q. Statement I: Protoplast fusion can be used to develop male sterile lines even between sexually incompatible species. 

Statement II: CMS lines developed through this method cannot be used with traditional CMS restorers.

Q. Assertion: Cybrids can be produced by the irradiation of protoplasts from one of the fusion parents. 

Reason: Irradiation effectively inactivates the nucleus of the donor protoplast, allowing only its cytoplasm to contribute to the fusion product.

Q. Assertion: Cybridization is a valuable tool for transferring traits like cytoplasmic male sterility (CMS) and herbicide resistance in crops like rice and tobacco. 

Reason: Cybrids contain the nuclear genome of only one species, which ensures the plant retains its primary species characteristics while gaining specific cytoplasmic traits.
