The ability of PHA accumulation is endowed by the PHA biosynthesis operon (phaCAB) encoding three enzymes (3-ketothiolase, acetoacetyl-CoA reductase and PHA synthase). Your project supervisor would like you to create a PHA-producing E. coli, by cloning and expressing the entire phaCAB operon from C. necator H16.. Table 16 Positive and Negative Regulation in the lac Operon Media Resources Animation 16 The lac Operon Animation 16 The trp Operon Recap and Assess 16. Gene expression in prokaryotes is most commonly regulated through control of transcription. An operon consists of two or more adjacent structural genes and a single the tryptophan (trp) operon and lactose (lac) operon. While there are many different operons, the general structure of all operons is the same. You should review the general structure of an operon before reviewing the details of a lac operon. A lac operon is an operon that controls genes responsible for the metabolism of lactose. Just like any James is working with the lac operon of Escherichia coli (E. coli). He places the bacteria on a plate of growth media. The lac Operon of E. coli is shown. Based on the current understanding of this operon, which hypothesis would be useful for James to test? Addition of allolactose (inducer) to the bacterial growth media should increase the speed at which the The lac Operon: An Inducible Operon. The lac operon is an example of an inducible operon that is also subject to activation in the absence of glucose (Figure Animated and descriptive video on trp Operon Attenuationtrp Operon Detail Video: trpOperon Tryptophan Operon How would removing the operator region from the E. coli tryptophan operon affect transcription of the trp genes? Choose one: A. Transcription of the operon could not occur, and the cells would require tryptophan in the growth media. B. Transcription of the operon would occur even if tryptophan were abundant. 1.11.1VLC Media Player 1.1.9VLC Media Player 1.1.8VLC Media Player 1.1.7VLC Media Player 1.1.6VLC Media Player 1.1.5VLC Media Player 1.1.4VLC Media Player 1.1.3VLC Media Player 1.1.2VLC Media Player 1.1.10VLC Media Player 1.1.1VLC Media Player 1.1.0 RC1VLC Media Player 1.1.0VLC Media Player 1.0.5VLC Media Player 1.0.3 RC1VLC Media Player 1.0.3VLC Media Player 1.0.2VLC Media Player 1.0.1VLC Media Player 1.0.0 RC4VLC Media Player 1.0.0 RC3VLC Media Player 1.0.0 RC2VLC Media Player 1.0.0 RC1VLC Media Player 1.0.0VLC Media Player 0.9.9VLC Media Player 0.9.8aVLC Media Player 0.9.8VLC Media Player 0.9.7VLC Media Player 0.9.6VLC Media Player 0.9.4VLC Media Player 0.9.2VLC Media Player 0.8.6iVLC Media Player 0.8.6hVLC Media Player 0.8.6fVLC Media Player 0.8.6eVLC Media Player 0.8.6dVLC Media Player 0.8.6cVLC Media Player 0.8.6b Test 1VLC Media Player 0.8.6bVLC Media Player 0.8.6aVLC Media Player 0.8.6 Test 2aVLC Media Player 0.8.6 Test 2VLC Media Player 0.8.6 Test 1VLC Media Player 0.8.6 RC1VLC Media Player 0.8.6VLC Media Player 0.8.5 Test 4VLC Media Player 0.8.5 Test 3VLC Media Player 0.8.5 Test 2VLC Media Player 0.8.5 Test 1VLC Media Player 0.8.5VLC Media Player 0.8.4aVLC Media Player 0.8.4 Beta 2VLC Media Player 0.8.4 Beta 1VLC Media Player 0.8.4VLC Media Player 0.8.2VLC Media Player 0.8.1VLC Media Player 0.8.0VLC Media Player 0.7.2VLC Media Player 0.7.1VLC Media Player 0.7.0VLC Media Player 0.6.2VLC Media Player 0.6.1VLC Media Player 0.6.0VLC Media Player 0.5.3VLC Media Player 0.5.2VLC Media Player 0.5.1VLC Media Player 0.5.0VLC Media Player 0.4.6VLC Media Player 0.4.5VLC Media Player 0.4.4VLC Media Player 0.4.2VLC Media Player 0.4.1VLC Media Player 0.4.0VLC Media Player 0.3.1VLC Media Player 0.3.0VLC Media Player 0.2.92VLCComments
