The key difference between clastogen and aneugen is that clastogen induces breaks in chromosomes, causing sections of chromosomes to be added, deleted, or rearranged, while aneugen affects the cell division and mitotic spindle apparatus, causing loss or gain of whole chromosomes. Genotoxicity is often described as the property of chemical agents to cause damages in […]
What is the Difference Between Activator Promoter and Repressor
The key difference between activator promoter and repressor is their function. An activator facilitates the upregulation of the transcription process by binding to enhancers, while promoter is the site at which RNA polymerase binds, and transcription initiation takes place, and repressor downregulates transcription by binding to silencers. Transcription is the process of synthesizing the complementary […]
What is the Difference Between 16s and 18s rRNA
The key difference between 16s and 18s rRNA is that 16s rRNA is a component of the 30S subunit in prokaryotic ribosomes while 18s rRNA is a component of the 40S subunit in eukaryotic ribosomes. Ribosomal RNA or rRNA is a structural component of ribosomes. rRNA is involved in the protein synthesis mechanism. Ribosomes of […]
What is the Difference Between Shuttle Vector and Expression Vector
The key difference between shuttle vector and expression vector is that shuttle vector is usually a plasmid that is not designed for gene expression studies in cells, while expression vector is usually a plasmid or virus that is designed for gene expression studies in cells. In molecular biology, a vector is a DNA molecule used […]
What is the Difference Between Adenosine and Deoxyadenosine
The key difference between adenosine and deoxyadenosine is that adenosine is a ribonucleoside that has ribose sugar moiety in its structure, while deoxyadenosine is a deoxyribonucleoside that has deoxyribose sugar moiety in its structure. Nucleosides are glycosylamines. A nucleoside consists of a nucleobase (nitrogenous base) and a five-carbon sugar. Based on the sugar moiety, nucleosides […]
What is the Difference Between RNA Polymerase Core and Holoenzyme
The key difference between RNA polymerase core and holoenzyme is that RNA polymerase core is an enzyme that does not have a sigma factor, while RNA polymerase holoenzyme is an enzyme that consists of a sigma factor. The transcription in bacteria is a process where a segment of bacterial DNA is copied into a newly […]
What is the Difference Between pBR322 and pUC19
The key difference between pBR322 and pUC19 is that pBR322 is a plasmid vector that is 4361 base pairs in length, while pUC19 is a plasmid vector that is 2686 base pairs in length. A cloning vector is a small piece of DNA that can be maintained in an organism stably. It is also a […]
What is the Difference Between T4 DNA Ligase and E Coli DNA Ligase
The key difference between T4 DNA ligase and E. coli DNA ligase is that T4 DNA ligase is an enzyme that is isolated from bacteriophage T4 while E. coli DNA ligase is an enzyme that is isolated from the bacterium E. coli. DNA ligase is a specific type of enzyme that facilitates the joining of […]
What is the Difference Between EcoRI and HindIII Restriction Enzymes
The key difference between EcoRI and HindIII restriction enzymes is that EcoRI is a type II restriction enzyme that is isolated from E. coli, while HindIII is a type II restriction enzyme that is isolated from Haemophilus influenza. Restriction enzyme or restriction endonuclease is an enzyme that cleaves DNA into fragments at specific recognition sites […]
What is the Difference Between PCNA and Ki67
The key difference between PCNA and Ki67 is that PCNA is a nuclear protein that participates in DNA synthesis and repair pathways, while Ki67 is a nuclear protein that participates in cell proliferation and ribosomal RNA transcription. Cell proliferation is a biological process that is essential to all living organisms. The control of this process […]
