Match each definition with given terms
|
1. Large family of structurally related, secreted, dimeric proteins that act as hormones and local mediators to control a wide range of biological functions in all animals. |
A. Rho |
|
2. Cell-surface receptor in which the cytoplasmic domain either has enzymatic activity itself or is associated with an intracellular enzyme. |
B. TOR pathway |
|
3. A crucial signaling protein in the PI-3-kinase–Akt signaling pathway, so named because it is the target of rapamycin. |
C. Enzyme-coupled receptor |
|
4. A kinase that is involved in intracellular signaling pathways activated by cell-surface receptors and that phosphorylates inositol phospholipids at the 3 position of the inositol ring. |
D. Phosphoinositide 3-kinase |
|
5. A group of monomeric GTPases that regulate both the actin and microtubule cytoskeletons. |
E. (TGFβ) superfamily |
|
6. Cytoplasmic tyrosine kinase present at cell–matrix junctions in association with the cytoplasmic tails of integrins. |

#Unit 3. Fundamental Processes
The transition from the closed to the open complex involves structural changes in the enzyme and the opening of the DNA double helix to reveal the template and nontemplate strands. This “melting” involves
A. Isomerization reaction and it does not require energy derived from ATP hydrolysis
B. Isomerization is essentially irreversible and, once complete, typically guarantees that transcription will subsequently initiate
C. Positions –11 and -2, with respect to the transcription start site.
