What are strands of replicated DNA?
During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces. DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
What are the 3 parts of replication?
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
What are the 3 main enzymes used in replicating DNA and what are their functions?
Enzymes involved in DNA replication are:
- Helicase (unwinds the DNA double helix)
- Gyrase (relieves the buildup of torque during unwinding)
- Primase (lays down RNA primers)
- DNA polymerase III (main DNA synthesis enzyme)
- DNA polymerase I (replaces RNA primers with DNA)
- Ligase (fills in the gaps)
What is replicate strand?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.
What are the five steps of DNA replication?
The viral replication involves five steps. They are : 1. Attachment 2. Penetration 3. Uncoating 4.Replication, transcription and translation, 5. Assembly and Release from host cell.
How many strands of DNA are formed during replication?
DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
What is the end product of DNA replication?
In replication, the end result is two daughter cells. While in transcription, the end result is a RNA molecule. Product. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA.
What is initial step in DNA replication?
“The first major step for the DNA Replication to take place is the breaking of hydrogen bonds between bases of the two antiparallel strands. The unwinding of the two strands is the starting point.”.
