What is the origin of replication in prokaryotes?
Replication in prokaryotes starts from a sequence found on the chromosome called the origin of replication—the point at which the DNA opens up. Helicase opens up the DNA double helix, resulting in the formation of the replication fork.
What is the difference between replication in prokaryotes and eukaryotes?
Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
What is DNA fingerprinting 12?
DNA fingerprinting. DNA fingerprinting. The process of comparison of DNA from different sources to establish the identity is called DNA fingerprinting. DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called as repetitive DNA.
What is a genome Class 12?
A genome is the complete set of genetic information of an organism. It contains all the instructions for creating and maintaining life. Every living organism consists of a genome. A human genome consists of nuclear and mitochondrial DNA. On the contrary, the genome of a virus comprises RNA as the genetic material.
Where is DNA replication in eukaryotes?
Comparisons between prokaryotic and eukaryotic DNA replication
| Prokaryotic DNA replication | Eukaryotic DNA replication |
|---|---|
| Occurs inside the cytoplasm | Occurs inside the nucleus |
| Only one origin of replication per molecule of DNA | Have many origins of replication in each chromosome |
What is a genome short answer?
A genome is an organism’s complete set of genetic instructions. Each genome contains all of the information needed to build that organism and allow it to grow and develop.
Who discovered DNA Ncert?
Also, in RNA the uracil is found at the place of thymine (5-methyl uracil, another chemical name for thymine). DNA as an acidic substance present in nucleus was first identified by Friedrich Meischer in 1869.
What is the difference between prokaryotic and eukaryotic replication?
Location. Prokaryotes do not have nucleus and other membrane-bound organelles,like mitochondria,endoplasmic reticulum,and golgi bodies.
Why is DNA replication faster in prokaryotes?
Prokaryotic. Replication also happens at a much faster rate in prokaryotic cells,than in eukaryotes.
Where does replication take place in prokaryotic cells?
prokaryotic cells
Does prokaryotic have DNA and RNA?
In prokaryotes, the DNA is not enclosed in a membranous envelope. The other type of nucleic acid, RNA, is mostly involved in protein synthesis. Similarly, you may ask, where is RNA found in prokaryotic cells? All prokaryotic cells contain large quantities of genetic material in the form of DNA and RNA.
