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.

The steps in the process of endochondral ossification are a: Ossification center forms in the diaphysis b: Cartilage calcifies a
irina1246 [14]

Answer:

During the development of the fetus, the mechanism by which the mammalian skeletal system gives rise to tissues of the bone is termed as endochondral ossification. Endochondral ossification also plays an essential role at the time of the development of the long bones length, rudimentary generation of the long bones, and healing of bone fractures naturally.  

The following are the steps in the process of endochondral ossification:  

f. The development of the cartilage model.  

b. The calcification of cartilage takes place and the formation of bone collar occurs.  

a. In the diaphysis, the formation of the ossification center takes place.  

c. In the epiphysis, the formation of ossification centers takes place.  

d. Replacement of cartilage takes place by the bone.  

e. Ossification of epiphyseal plates takes place.
