What is the difference between replication and duplication of chromosomes?
Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled.
Are replication and duplication the same?
Trick to Remember the Difference A duplicate is an exact copy of something. A replicate is only a reproduction, even if it is not exact.
What is a duplicated chromosome?
Chromosome duplication: Part of a chromosome in duplicate. A particular kind of mutation involving the production of one or more copies of any piece of DNA, including sometimes a gene or even an entire chromosome. A duplication is the opposite of a deletion.
What is the difference between replication and replication of DNA?
DNA replication is defined as the process involved in obtaining two daughter strands where each strand contains half of DNA double helix. This happens in the S phase of the cell cycle….Replication vs Transcription.
| Replication | Transcription |
|---|---|
| Found along the DNA strand | Found only along 1 strand of DNA |
| Raw material |
What are the differences between replication and transcription?
1. DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template.
What is the difference between replicate and copy?
As nouns the difference between replication and copy is that replication is process by which an object, person, place or idea may be copied mimicked or reproduced while copy is the result of copying (confer original); an identical duplication.
Why do chromosomes replicate?
During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two “daughter” cells that inherit the same genetic information.
Can you tell the difference between the original and the replicated strand?
Can you tell the difference between the original and the replicated strand? The strands are suppose to be exactly same when replication is complete, so you would not be able to tell the difference.
What is the structure of a replicated chromosome?
A replicated chromosome (or equivalently, a duplicated chromosome) contains two identical chromatids, also called sister chromatids. The difference between a duplicated chromosome and a chromatid, strictly speaking, is that a chromosome contains two chromatids that are joined at a structure called a centromere.
How many chromosomes are in a duplicated chromosome?
46 chromosomes
II. S phase (DNA Synthesis) – Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2) – The Cell “double checks” the duplicated chromosomes for error, making any needed repair.
What is the duplication of DNA called?
DNA replication is the process by which a molecule of DNA is duplicated. When a cell divides, it must first duplicate its genome so that each daughter cell winds up with a complete set of chromosomes.
