Anaphase promoting complex (APC) is a protein degradation machinery necessary for proper mitosis of animal cells. If APC is defective in a human cell, which of the following is expected to occur

Chromosomes will not condense

Chromosomes will be fragmented

Chromosomes will not segregate

Recombination of chromosome arms will occur

Text Solution

Verified by Experts

The correct Answer is:

If anaphase promoting complex is defective in a human cell, the chromosomes will not segregate during anaphase of mitosis. APC triggers the transition form metaphase to anaphase by tagging specific proteins for degradation.
Concept Enhancer Anaphase stage of mitosis is characterised by two events
(a) Splitting of centromeres and segregation of chromosomes.
(b) Movement of chromatids towards the opposite poles .

By comparing mitosis and meiosis occurring in the same organism, which ONE of the following options is CORRECT regarding the DNA content per cell?

C-value is the characteristic DNA content in a haploid cell of a given species. Earlier it was considered that C-value correlates with organism complexity. However, it is now evident that C-value varies enormously among species and this bears no correlation with the complexity of hte organisms . For example, the cells of some salamanders may contain 40 times more DNA than those of humans. Which of the following explains this C-value paradox?

The break-down of glucose in a cell occurs in any of the following pathways : Three experiments (A, B, C) have been set up. In each experiment, a flask contains the organism in growth medium, glucose and a brown dye that changes its colour to yellow when the pH decreases. The mouth of the flask is attached to a test tube containing lime water (Calcium hydroxide , as shown in the figure) . In C, but not in A and B , air is removed from the flask before beginning the experiment. After a period of growth, the following observation were made : A : Lime water turns milky , the dye colour remains the same B : The dye colour changes , lime water does not turn milky C : Lime water turns milky , the dye colour remains the same (a) Question : Identify which of the reactions is the pathways depicted above is taking place in each experiment . Give reasons for your answer . (b) Question : Identify which of the reactions in the pathways depicted above is expected to occur in Red Blood Cells (RBCs)

The given statements describe a group of organisms. (i) Instead of a cell wall they have a protein rich pellicible making their body flexible. (ii) They have 2 flagella, a short and a long one. (iii) They show mixotrophic nutrition (iv) They are connecting link between plants and animals. which of the following groups is referred to here?
