question
Which of the following concerning the nuclear envelope ?
answer
envelope is particularly important in mitosis.
question
The mRNA start codon , AUG , matches up with a tRNA anticodon
answer
UAC
question
Match the form of A with its function : tRNA
answer
Uses an anticodon to guide its attached amino acid to the complementary codon on the mRNA at the ribosome
question
Match the stage of mitosis with the event(s) that occur(s): prophase
answer
Chromatin condenses into chromosomes; centrioles move toward opposite poles of the cell.
