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.

In two or more complete sentences, describe an activity you perform that has an impact on climate change? Is it positive or nega
Phoenix [80]

Answer:

Burning of woods has a negative impact on the climate.

Explanation:

Burning of woods for heating has a negative impact on our climate because it releases carbondioxide gas which is a greenhouse gas that trapped the reflected solar radiation and leads to global warming. We have to used alternative methods for heating such as electric heater instead of burning of wood which produce no pollution and can fulfill the requirement of heating so from the above discussion we can say that the activity has a negative impact on the environment.
