QUESTION 7

Which of the following is FALSE regarding Dissociator? (Choose the one correct answer.)

Movement of Dissociator only occurs during early development.

It is a transposable genetic element.

It \'s presence within a color gene disrupts pigment production.

It\'s movement is controlled by a second element called \'Activator\'.

True

False

QUESTION 9

Which of the following statements is TRUE regarding the cell cycle? Choose ALL that APPLY.

CDKs are downregulated by cyclins.

Mature, differentiated cells exit the cell cycle into a resting phase called G0.

DNA damage that occurs after the Restriction Point will not arrest the cell cycle since the cell has passed the \'point of no return\'.

CDKs are activated by CKIs

QUESTION 10

Homeotic genes display spacial colinearity.

True

False

Solution

5. Yes, it is true that the RNA components of the mRNA splicing machinary be responsible for the splicing of mRNA not the protein of the splicing machinary.

Small nuclear riboproteins are responsible for the splicing of the mRNA.

6. The false statement is \"Alternative splicing occurs at extremely high levels in nervous tissue\".

Since Alternative splicing is tissue specific but it has no any concern with the nervous tissue.

7. The false statement is \"Movement of Dissociator only occurs during early development.\"

8. Yes, An antigen can be a protein, nucleic acid, or a polysaccharide.

9. The true statements are \"Mature, differentiated cells exit the cell cycle into a resting phase called G0.\" and \"DNA damage that occurs after the Restriction Point will not arrest the cell cycle since the cell has passed the \'point of no return\'.\"

10. Yes, it is true that Homeotic genes display spatial colinearity.
