It is d) to continue the species!!
hope this helps :)
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.
I think it’s D i hope i’m right
Answer: Lysosome
Explanation:
The lysosome is an organelle found in cells of eukaryotes.
Its functions include:
I) It contains several hydrolytic enzymes such as
- glycosidases that break down complex sugars (polysaccharides),
- proteases that break down proteins,
- and sulfatases that hydrolyze sulphur-containing compounds,
- other enzymes for lipids and Nucleic acids
II) it also digest worn out organelles, and engulfed viruses and bacteria.
III) and helps to remove wastes from the cell.
Technically, it would create an identical copy of the parent cell, but with the answers you gave me, I would have to say the first response. Sexual reproduction provides half the genetic information, a half from one parent and a half from the other.
I hope this helps!!!! :)
