Biology
2 answers:
SashulF [63]3 years ago

Answer:

compound

Explanation:

Sheets can be grouped into two basic groups: single sheets and composite sheets. The simple leaves are those in which the limb is not divided. The composite leaves, in turn, have the limbus divided into small portions called leaflets. Each leaflet may also have a small petiole, which in this case is called a petiole.

Composite leaves can be further classified into two types: pinnacles and spankings. Pinnacles are those in which leaflets start from the rake (petiole extension) as a feather. The spanking, in turn, has its leaflets starting at the very end of the petiole.

What is the Molecular mechanism of DNA replication?
kolezko [41]

Answer:

DNA replication a process of copying of a cell's DNA.  DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.

The Molecular mechanism of DNA replication is as following:

  1. The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
  2. A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
  3. Topoisomerase prevent supercoiling at replication fork.
  4. The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
  5. DNA polymerase III help to extends the primers and allow them to add  to the 3' end, to make new DNA.
  6. DNA Polymerase then remove RNA primers and replace with DNA.
  7. DNA ligase blocks the the gaps between DNA fragments.

So, this is the molecuar mechanism of DNA replication.
