How was Bohr's atomic model similar to Rutherford's model?
it described a nucleus surrounded by a large volume of space.
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:
- The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
- A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
- Topoisomerase prevent supercoiling at replication fork.
- The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
- DNA polymerase III help to extends the primers and allow them to add to the 3' end, to make new DNA.
- DNA Polymerase then remove RNA primers and replace with DNA.
- DNA ligase blocks the the gaps between DNA fragments.
So, this is the molecuar mechanism of DNA replication.
Answer:
An effective strategy for stepping in if someone appears to need help is <u>directly check in with the person</u><u>.</u>
Explanation:
Many a time, our closed ones will be fighting battles we are unaware of. We are so busy in our lives that we either do not notice the problems of our loved ones or we just think that if they need help from us, they will ask it themselves. But we shall realize the fact that many people will not ask for help themselves due to certain reasons.
So, it is best to always check upon the persons you love if you think that they might need any help.
