The key difference between DNA profiling and genetic screening is that DNA profiling is the process of determining the DNA characteristics of an individual, whereas genetic screening is the process of testing a population for a genetic disease. Gene tests study DNA sequences to identify variations in genes that cause or increase the risk of […]

The key difference between snRNA and snoRNA is that snRNA involves the alternative splicing of pre-mRNA while snoRNA involves modifying rRNA and tRNA, mRNA editing, and genome imprinting. Small RNA are polymeric RNA molecules that consist of less than 200 nucleotides. They are usually non-coding. They exist among messenger RNAs to carry signals. Small RNAs […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
