What is the role of enzymes in the DNA replication process?
Enzymes split the DNA molecule into two strands and then transport corresponding nitrogenous bases to each strand.
Enzymes link together to form a template for a new DNA molecule to be built.
Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Enzymes read the DNA code and build a new DNA molecule from scratch.
Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
The correct answer is:
Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
The correct answer is: Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
To explain how enzymes are involved in the DNA replication process, let's break it down step by step:
1. DNA replication starts with the separation of the double-stranded DNA molecule. An enzyme called helicase unwinds and unzips the DNA, breaking the hydrogen bonds between the two strands.
2. Once the DNA strands separate, another enzyme called DNA polymerase comes into play. DNA polymerase is responsible for building the new strands of DNA.
3. In order to build the new strands of DNA, DNA polymerase needs a starting point, called a primer. The enzyme Primase synthesizes a short RNA primer that provides the starting point for DNA polymerase to attach.
4. DNA polymerase then adds nucleotides to the growing DNA chain, using the existing strands as templates. The enzyme links the nucleotides together, forming a consistent and complementary sequence to the original DNA strand.
5. As the new DNA strands are being synthesized, another enzyme called DNA ligase seals any gaps that may exist between the newly synthesized DNA fragments. DNA ligase creates phosphodiester bonds to connect the adjacent nucleotides, resulting in a continuous DNA strand.
Thus, enzymes, particularly DNA polymerase, play a crucial role in the DNA replication process by linking adjacent nucleotides and forming the new strands of DNA.
