I believe in the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and therefore, slow the rates of glycolysis and the citric acid cycle. Phosphofructokinase is and enzyme that phosphorylates fructose 6 phosphate in glycolysis. It is an important control enzyme in the regulation of cellular respiration. It is inhibited by ATP and is an allosteric enzyme.
Answer:
C. II and IV only
Explanation:
X linked recessive inheritance follows the criss-cross pattern in which affected mothers always have affected sons as sons get their X chromosome from mothers only. Condition "II" can not be true for X linked inheritance as hemophiliac mothers (XhXh) should have hemophiliac sons (XhY) only.
Daughters get one copy of their X chromosome from the father and the other from mother. To have affected daughters, mother should be carrier or hemophiliac and the father should be hemophiliac (XhY). This would make it possible for both the parent to transmit one copy of X chromosome with the gene to daughters (XhXh).

They first 'cut out' genes using precise biological 'scissors' – restriction enzymes – and paste them into DNA from another organism like a bacterium or yeast where it is copied many thousands or millions of times. Molecular model of a restriction enzyme bound to DNA.
The correct answer is B)attachment of microtubules to kinetochores.
Mitosis is a process of cell division in which newly replicated chromosomes separated equally into two parts of a cell. During late prophase of the mitotic cycle, the nuclear envelope breaks down or disappear. This allows attachment of the microtubules to the kinetochores of sister chromatids at the metaphase-anaphase transition. The attachment finally leads to the formation of two daughter cells.
