If all the ATP are radiolabelled in the cytosol, then predict about radioactivity of each compound.

 a) All enzyme  of glycolysis will be radiolabelled except 2-phophoglycerate and phosphenol pyruvate

 b) 2-phophoglycerate and phosphenol pyruvate are radiolabelled only the next cycle of glycolysis after cytosolic ATP radiolabelling

 c) 1,3 bisphosphoglycerate will be radiolabelled at 1 and 3 both position

 d) 2-phosphoglycerate are not radiolabelled because its enzyme phosphoglycerate mutase active site contain histidine residue exchange phosphate group from 3-phosphoglycerate

 which prediction about radiolabelling is incorrect?

With respect to X-chromosome inactivation, which, if any, of the following statements are not correct? 

I. X-chromosome inactivation in mammals begins in the pre-implantation embryo 

II. In humans all diploid cells that carry two normal X-chromosomes are subject to a random pattern of X-inactivation. 

III. Once a decision has been made to inactivate an X chromosome (either the paternal or maternal X), all descendant cells show the same pattern of X-inactivation. 

IV. The inactivated X chromosome becomes a highly condensed Barr body in which genes are silenced across the length of the chromosome.
