Cap binds as a homodimer to specific dna sequences upstream of genes involved in the metabolism of sugar, but only when the protein is complexed with camp. cap activates transcription by contacting rna polymerase. identify the regions of the protein that are responsible for dimerization, dna binding, and camp binding.

a. dimerization (1), dna binding (4), camp binding (3)
b. dimerization (4), dna binding (6), camp binding (5)
c. dimerization (4), dna binding (1), camp binding (3)
d. dimerization (6), dna binding (1), camp binding (2)

Fill in the blank 1. digestion occurs in the small intestine through the action of enzymes. 2. urea, excess water, and other waste materials are eliminated in a water fluid called 3. can cause infections by injecting dna or rna into hosts. 4. the human immune system produces in response to a vaccine, which later can bind to and destroy a pathogen if it invades. 5. are structures that link bone to bone at a joint 6. in the heart, blood flows from the right atrium to the right ventricle, where it is pumped to the the words i can use are: lymphocytes gliding pivot gas urine absorption dermis fulcrum lungs chemical viruses capillary vertebrae esophagus tendons antibodies synapses ligaments kidneys pathogens
