Question
Q/How does the Ras protein transmit a signal from outside the cell into the cytoplasm?
a) Inactivated Ras proteins transduce a signal, which activates the transcription of genes that start cell division. b) Activated Ras proteins transduce a signal, which activates the transcription of genes that start cell division. c) Activated Ras proteins transduce a signal, which inactivates the transcription of genes that supress cell division. d) Inactivated Ras proteins transduce a signal, which inactivates the transcription of genes that supress cell division.Explanation / Answer
b) Activated Ras proteins transduce a signal, which activates the transcription of genes that start cell division
Cell growth promoting signal is linked to the Ras type protein,Ras type protein is a monomeric guanine nucleotide binding proteins, having the GTPase activity, it is inactive condition when GDP is bound and active when bound to GTP
