Back (Answer)

Not translated into protein. “Non-translated genes.”

#7
Front (Question)

T or F RNA polymerase doesnt need a primer?

Back (Answer)

T. unlike DNA polymerase in replication RNA polymerase does not need a primer to start sythesiing RNA 5’-3’.

Back (Answer)

• Which transcribe different types of RNAs

#11
Front (Question)

Bacteria have how many RNA polymerase?

Back (Answer)

1.activity is modualted by sigma factors.
