Answer:

Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?

Explanation:

Based on the information provided within the question it can be said that the question that would best bring about investigation onto this hypothesis would be "Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?" as it brings up the most important topic, of how could RNA have developed into DNA?

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.

Explain how biodiversity contributes to maintaining different life form on earth ​
gulaghasi [49]

Answer:

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. It keeps the "balance" in nature.
