The key difference between group I and group II introns is that in group I introns, the splicing reaction is initiated by a guanosine cofactor, while in group II introns, the splicing reaction is initiated by internal adenosine. Pre-mRNA is the primary transcript that has both introns and exons. Pre-mRNA should convert into mRNA prior […]
Difference Between Ion Channel and Ion Pump
The key difference between ion channel and ion pump is that ions move passively through ion channels while ions move actively through ion pumps. Ions travel across the plasma membrane through ion channels or ion pumps. Ion channels are transmembrane proteins that passively transport ions down their electrochemical gradient across the cell membranes. Ion pumps […]
Difference Between Endocytosis and Endoreduplication
The key difference between endocytosis and endoreduplication is that endocytosis refers to the cellular process of moving substances into living cells by invagination of the cell membrane to form a vesicle while endoreduplication refers to the process of undergoing multiple S phases or multiple rounds of nuclear genome replication without entering nuclear division or mitosis. […]
Difference Between Amniocentesis and Cordocentesis
The key difference between amniocentesis and cordocentesis is that amniocentesis is done using a sample of amniotic fluid while cordocentesis is done using a blood sample of the umbilical cord. Amniocentesis and cordocentesis are two prenatal diagnostic procedures that are used to detect chromosomal abnormalities and other fetal medical conditions. Both procedures are invasive. Hence, […]
Difference Between Nitrosomonas and Nitrobacter
The key difference between Nitrosomonas and Nitrobacter is that Nitrosomonas is a bacterium that converts ammonium ions or ammonia into nitrites while Nitrobacter is a bacterium that converts nitrite into nitrates in the soil. The nitrogen cycle is an important biogeochemical cycle. Nitrogen cycle occurs via four major processes: nitrogen fixation, ammonification, nitrification and denitrification. […]
Difference Between Cis and Trans Fat
The key difference between cis and trans fat is that in cis fats, the two H atoms are present on the same side of the double bond while in trans fats, two H atoms are present on the opposite sides of the double bond. Fats or fatty acids are carboxylic acids comprised of a straight chain […]
Difference Between Electroporation and Microinjection
The key difference between electroporation and microinjection is that electroporation is a technique that uses a high voltage electric pulse to deliver DNA into host cells while microinjection is a technique that uses a fine-tipped glass needle or micropipette to deliver DNA into host cells. Transformation is the process by which foreign DNA is transferred […]
Difference Between pre-mRNA and mRNA
The key difference between pre-mRNA and mRNA is that pre-mRNA is the first product of the transcribed gene and contains both non-coding sequences (introns) and coding sequences (exons) while mRNA is the second product of a transcribed gene which contains only coding sequences. Gene is the functional unit of heredity. It is a specific DNA […]
Difference Between Symmetric and Asymmetric Stem Cell Division
The key difference between symmetric and asymmetric stem cell division is that symmetric stem cell division produces two differentiated cells or two stem cells with equal cell fates while asymmetric stem cell division produces one stem and one non-stem daughter cell, which have different fates. Stem cells are undifferentiated cells that can proliferate indefinitely. They can differentiate into […]
Difference Between Operon and Cistron
The key difference between operon and cistron is that operon is a functional DNA unit present in prokaryotes and consists of several genes that are regulated by a single promoter and an operator while cistron is a term used to refer a gene, which is the functional unit of heredity that code for a protein. […]
