Which of the following is the enzyme that replaces the RNA nucleotides in a primer with DNA nucleotides?

DNA polymerase III
DNA polymerase I
primase
helicase

Respuesta :

Answer: The correct answer would be DNA polymerase I.

Explanation:

DNA polymerase III is a holoenzyme and a primary DNA polymerase which mainly performs the function of DNA replication.

Primase is the enzyme which adds short RNA primers to the template DNA which help in starting the DNA replication process.

Helicase is the enzyme which helps in separating the two strands of DNA during replication.

DNA plymerase I is the enzyme which helps in DNA repair and joining Okazaki fragments. It removes RNA primers and joins the fragments.

The DNA polymerase I enzyme replaces the RNA nucleotides in a primer with DNA nucleotides.

What is a DNA polymerase enzyme?

DNA polymerase I is an enzyme that catalyzes the synthesis of a DNA strand during DNA replication.

  • This DNA pol I can replace nucleotides from an RNA short segment in a primer with DNA nucleotides.

  • DNA primase is an enzyme involved in the catalytic activity of a short RNA fragment.

In conclusion, the DNA polymerase I enzyme replaces the RNA nucleotides in a primer with DNA nucleotides.
