CSSR may require all of the following except__________

cis-acting elements in the target (i.e. the recipient) DNA

Rec A, B and C

a sequence specific DNA binding nuclease/DNA ligase

some architectural (non-enzymatic) proteins to aid the process

cis-acting elements in the donor DNA

Expert Solution

Rec A, B and C

DNA strand with a certain degree of sequence homology will undergo site-specific recombination and here the site-specific recombinases (SSRs) will perform the rearrangements of DNA segments by recognizing it and will go and bind to the short DNA sequences, and then cleave the DNA backbone in order to exchange the two DNA helices which are involved and finally rejoin the DNA strands. The CSSR needs everything except Rec A, B and C as the process will occur independent of Rec proteins.

The necessary components for gene expression are often described as either cis-acting elements (“acting from the same molecule”) or trans-acting factors (“acting from a different molecule”). Cis-acting elements are typically sequences that are required for expression. Trans-acting factors are typically proteins that recognize and bind cis-acting sequences to control or facilitate gene expression. For each of the cis-acting elements below, Promotor and Start Codon,list a trans-acting factor involved in its recognition and describe the factor’s normal function

Consider the lac operon in E. coli. a. List the cis-acting elements and the trans-acting factors involved in the regulation of its expression. b. Indicate which Transacting factors interact with which cis-elements. c. Describe what the factors do when they are bound to their respective cis–elements. d. Indicate the inducer in this system and how it works.
