Question 8 Gene regulation in prokaryotes usually occurs by
controlling whether or not genes are transcribed to mRNA
O controlling whether or not mRNAs are translated to protein
controlling which introns are removed
o controlling the stability of mRNAS
o all of the above

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

catya your not at all which answer i've seen you do this on another question!
