What happens in replication and translation?
The replication of DNA is semi-conservative and depends on complementary base pairing. Transcription is the synthesis of mRNA copied from the DNA base sequences by RNA polymerase. Translation is the synthesis of polypeptides on ribosomes.
When does DNA replication occur?
DNA replication occurs during the S-stage of interphase. DNA replication (DNA amplification) can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to start DNA synthesis at known sequences in a template DNA molecule.
What are the 6 steps of replication?
Key Points
- Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release.
- During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
When does replication occur?
DNA Replication occurs during the second stage of the Mitosis or cell cycle. The second stage being the S phase or synthesis phase. This phase happens between the G1 and G2 phases. In those two phases the cell is growing in size to have enough cytoplasm and to be big enough to split.
What transformation occurs during replication?
Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA). Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell.
At what point does DNA replication occur and why?
DNA replication occurs during the S phase (the Synthesis phase) of the cell cycle, before mitosis and cell division. The base pairing rules are crucial for the process of replication. DNA replication occurs when DNA is copied to form an identical molecule of DNA.
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.
What is the third step in DNA replication?
Third Step of DNA Replication. DNA Polymerase moves along the DNA strands attaching free floating nucleotides to the open strands.
What are the problems of DNA replication?
Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer .
What is a simple explanation of DNA replication?
Definition. DNA replication is a process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA.
