Question

Proteins that are involved in the regulation of the cell cycle, and that show fluctuations in concentration during the cell cycle, are called ____ O centrioles o cyclins phosphatases O kinases O ATPases

Answer 1

Correct Answers with explanations are given below :-

Proteins that that show cycle, are involved in fluctuations called - the in regulation of the cell cycle, and concentration during the cell Ans> Cyclins explanation Two groups of proteins, called cyclins and cyclin depen- dent kinases (edks) are responsible for the progress of the cell cycle. The levels of the four cyclin Proteins fluctuate throughout the cell cycle. - 4 cyclin proteins are - cyclind , cycline, cyclina, cyclin B.

you wish to insert a gene involved in the degradation of a toxic compound into a plasmid , and then use the plasmid as a vector to troms form a species of bacteria so that it can be wed in a bioremediation effort to clean up hazardous waste. In order to accomplish this, you will need to Any Digest both the gene and plasmid with the same sustriction enzymes in order to yield appropriate "sticky ends that can anneal. use Ligase to fermanently join together the ends of the gene with the plasmid lie. form coralent bmds between them). explanation Plasmid - Target gene Digested with some restriction entine sticky ands join thim bay wong ligase Recombinant ploomid Grow up lots of Transform recombinant Plasmid into bacteria Plasmid-carrying bacteria. first we need some restriction entyme to cut both gene and plasmid and then agt join them by ligase and troms foron into a bee species of bacteria. bacteria divide rapidly, they can be used as factories to copy DNA fragments in large amount and make Poroleins.
