Which describes DNA replication in prokaryotes?

DNA Replication in Prokaryotes: A replication fork is formed when helicase separates the DNA strands at the origin of replication. On the leading strand, DNA is synthesized continuously, whereas on the lagging strand, DNA is synthesized in short stretches called Okazaki fragments.

What happens in DNA replication?

DNA replication is the process by which DNA makes a copy of itself during cell division. The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.

What is the role of the DNA polymerase in DNA replication answers com?

DNA polymerase make single strand of DNA into double stranded DNA by adding suitable bases.

What are two functions of DNA polymerase during replication?

DNA polymerase creates two new strands that are identical to those that already exist. DNA polymerase adds nucleotides to the three prime end of a DNA strand one nucleotide at a time. When a cell divides, DNA polymerases are needed so that the cell’s DNA can duplicate.

What does a chromosome look like after DNA replication?

When fully condensed, replicated chromosomes appear as thick X-shaped structures that are readily observed under the microscope (see figure below). Chromosomes can have 1 or 2 chromatids, depending on whether they have replicated.

What are the key players in DNA replication?

DNA replication employs a large number of proteins and enzymes, each of which plays a critical role during the process. One of the key players is the enzyme DNA polymerase, also known as DNA pol, which adds nucleotides one by one to the growing DNA chain that are complementary to the template strand.

What are the 4 key players in DNA replication?

Terms in this set (5)

  • DNA polymerase III. leading and lagging strand synthesis.
  • Ligase. seals the nick in the phosphodiester bond between two Okazaki fragments.
  • Helicase. breaking the hydrogen bond between nitrogenous bases, generating single stranded DNA templates.
  • Topoisomerase.
  • Primase.
