Why can't both strands of DNA be replicated at the same time?

saw5 [17]

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.

DNA Replication:

Step one: 

DNA Helicase (unzips) separates the strands.

Step two:

DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.

Step three:

DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.

The leading strand is made continuously.
The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.

Step four:

Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.

Step five:

Another DNA Polymerase fills in the gaps that are left behind with DNA.

Step six:

DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.

Final answer:

DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Good luck!

Explain why glucose and galactose do not interconvert as the ring forms open and close again. Select the correct answer below: T

lakkis [162]

Answer: The difference between structures of glucose and galactose occurs at a carbon other than the anomeric carbon.

Explanation: The cyclic structure of glucose and galactose is cannot be inter converted because the change does not occurs at the anomeric carbon.

It takes place at carbon number 3 ( Fisher's projection)which does not takes place in the opening and closing of the rings.

Anomeric carbon are the carbon that takes place in the opening and closing of the rings.
