Investigators introduce two proteins into the membrane of artificial lipid vesicles: (1) an ATP synthase isolated from the mitochondria of cow heart muscle, and (2) a light-activated proton pump purified from the prokaryote Halobacterium halobium. The proteins are oriented as shown in the diagram. When ADP and P; are added to the external medium and the vesicle is exposed to light, would this system produce ATP? H LIGHT protein pump ATP synthase Choose one: O No, because no electron-transport chain...

Identify the most accurate term related to chromatin remodeling. DNA is associated with proteins to form. A is compsed of DNA wrapped around an octamer of histone proteins. An activator can increase transcription by attracting a to the region. Addition of (-COCH_3) groups to histone amino terminal tails results in a/an in gene expression. Removal of acetyl groups from histones results in a/an in gene expression.

Which is the most inappropriate description of a ribosome? Select one: a. It consists of proteins and rRNAs. b. It has pockets for at three tRNA bindings. c. For initiation, the 30S subunit binds to mRNA before the 50S subunit binds. d. For its translational function, ribosome needs other protein factors. e. Ribosomes carry out translation at consumption of the energy from ATP.
