Can an enzyme be recycled? Explain.
ser-zykov [4K]

Answer:

Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.

3. What is peptidoglycan?
Dvinal [7]

Answer:

A combination of polypeptides and modified sugars that enclose the entire eubacteria.

Explanation:

A component of bacterial cell walls called peptidoglycan (PGN) promotes innate immune responses. Peptidoglycan, a polymer made of sugars and amino acids, creates the cell wall of the majority of bacteria by producing a layer that resembles a mesh outside the plasma membrane. N-acetylglucosamine and N-acetylmuramic acid residues are alternated in the sugar component. forms a saccules in the cell wall of most bacteria that resembles a bag. It controls bacterial cell shape and is crucial for osmotic stability. A heteropolymer made up of glycan strands carrying small peptides is known as a peptidoglycan.

URGENT!! PLEASE HELP!!!

In complementary base pairing, the G pairs with C, and A pairs with T. Given that this be the rule, the complementary nucleotides for your sequence would be as follows: CGATTAACGTAGGCA.

With regards to proofreading, mutations in cell division occur once in around every 100,000 base pairs. If this happens, the enzyme that pairs the nucleotides to form DNA, called DNA polymerase, detects the error and moves back along the strand, it then cuts the incorrect nucleotide and replaces it with the correct one, fixing the error and continuing with the DNA synthesis.
This process corrects the majority of errors in DNA synthesis, but some errors can still be missed by the DNA polymerase, this is then rectified by a protein complex which binds to the incorrect pairing until anther complex, comes along and cuts that particular section of DNA out, which is then replaced by a new section of correct nucleotides synthesized by the polymerase enzyme, the two sections at either end that were cut is then sealed by ligase, an enzyme which essentially "glues" the DNA stands back together.

My apologies for the long answer, I hope I answered your question and that you understand it well enough.
