Choose the wrong one.
A. The cdc gene products are required for normal cell cycle
B. The cdc gene are needed for structural purposes
C. They are involved in regulation of cell cycle
D. The cdc mutants are temperature insensitive
Answer: Option D
Solution(By Examveda Team)
From the given statements about cdc gene and cell cycle, the last statement that cdc mutants are temperature insensitive is wrong while all other are correct.Genes that code for proteins that regulate the CELL DIVISION CYCLE. These genes form a regulatory network that culminates in the onset of MITOSIS by activating the p34cdc2 protein.
Cdc genes are temperature sensitive. A total of 59 new temperature-sensitive cdc mutants are described which grow normally at 25°C but become blocked at DNA replication or mitosis when incubated at 36°C.
