Help pls- <br><br> compare and contrast evaporation and boiling
DENIUS [597]
So the simple answer would be evaporation is slow and can only occur through the surface of a liquid and it cools it down, while boiling is fast and produces bubbles ( evaporation does not ) and it occurs throughout the liquid and doesn’t cool it down. A similarity between the two would be water vapor is given off
Both the processes of evaporation and boiling result in a change from liquid to vapor.

hope this is what u we’re looking for and this helps !! :)

You are performing a biochemical purification of enzymes involved in DNA replication. You have purified the replisome. You wish
algol [13]

Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA

  • The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:

            1. Helicase enzymes that unwind and separate the DNA strand

            2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.

           3. Proliferating cell nuclear antigen (PCNA)

           4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.

           5. Primase enzyme that synthesizes short RNA fragments called primers.

          6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.

           7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA

  • A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.
  • The primosome is composed of different primase and helicase enzymes. In<em> Escherichia coli</em>, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.
