trigger a response by their buildup along the cell membranes, stopping key materials from entering the cell

must use atp to enter the cell, releasing adp into the cytoplasm, which then becomes cyclic amp

Drag each label to the correct location on the image. each label can be used more than once. a scientist introduced mutations in a gene sequence isolated from bacteria. study the sequence, and identify the steps where the mutations may affect the formation of proteins. in the sequence, black letters stand for protein coding regions and red letters stand for noncoding regions. protein will not be changed. protein may be changed. attcgtgttc atcgtgttc atcgtattc attcgtattc
