Autocrine signaling is a type of:

Dyneins are ______ than kinesins and walk towards the ______ end of microtubules.

The image below shows steps in a phosphorylation cascade (1-5).  Match the proteins (A-E) from the box on the right to the correct steps in the cascade figure below to the left:   Step 1[1],   2 [2],   3 [3],   4 [4],   5 [5].  Just use the uppercase letter (and not the name of the enzyme) to fill in the blanks.

Which of the following extracellular signals binds to intracellular receptors?

Which of the following terms is NOT a microtubule-binding protein?

Intermediate filaments are found in the:

During kinesin movement, the trailing head moves forward to become the leading head upon:

The apicomplexan parasite Plasmodium falciparum causes malaria, a disease that kills hundreds of thousands of people each year. P. falciparum has an apicoplast, which is responsible for metabolite biosynthesis of essential isoprenoid precursors. Apicoplasts emerged after an endosymbiosis event. Thus, they share many genes with their red algal ancestors and with prokaryotes but few with humans. Based on your knowledge of apicomplexans and P. falicparum, which of the following theoretical drugs are likely to help treat malaria?

Cellular responses that require transcription and translation usually occur on the time-scale of:

The ______-subunit within heterotrimeric G-proteins is structurally similar to monomeric G-proteins.
