In dna replication, the strands on the original molecule are used as blank______ for the synthesis of new dna strands.

1 answer:

5 0

The strands on the original DNA molecule serve as templates for the creation of new DNA strands during DNA replication.

<h3>What is DNA templates?</h3>

Because it includes the instructions a cell needs to survive, the genetic code is commonly referred to as a "blueprint." However, we now understand that these instructions are more complex than just the arrangement of the letters in the nucleotide code. For instance, copious evidence suggests that this code serves as the blueprint for the synthesis of numerous substances, including RNA and protein.

Additionally, studies have demonstrated that transcription and translation take place in order to "read" the DNA instructions that are stored there. A single-stranded RNA molecule is created during transcription from a piece of the double-stranded DNA template. In some instances, the RNA molecule is a "finished product" that performs a crucial task for the cell.

Answer: It is Hypertonic solution.

Explanation:

Hypertonic solution is a solution in which the the solutes Concentration outside the cells is greater than solute concentration inside the cell. When a cell is in Hypertonic solution, water will move out of the cell and it will shrivel. The cell will shrinks or cremated and may eventually die.

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!
