The key difference between screening mammogram and diagnostic mammogram is that a screening mammogram is a simple x-ray taken without any signs or symptoms of breast cancer, while diagnostic mammogram is a more detailed x-ray done based on signs and symptoms of breast cancer. A mammogram is an x-ray image of the breast. It is […]
What is the Difference Between NRF1 and NRF2
The key difference between NRF1 and NRF2 is their function. NRF1 is a transcription factor that activates the expression of some important metabolic genes that regulate cellular growth and nuclear genes required for respiration, heme biosynthesis, mitochondrial DNA transcription, and replication, while NRF2 is a transcription factor that regulates the expression of antioxidant genes that […]
What is the Difference Between Gap Junctions and Plasmodesmata
The key difference between gap junctions and plasmodesmata is that gap junctions are the channels between adjacent animal cells, while plasmodesmata are channels between adjacent plant cells. Gap junctions and plasmodesmata are two types of cell-cell interactions in animals and plants. Cell-cell interaction is the direct interaction between two cell surfaces. Cell-cell interaction plays a […]
What is the Difference Between snRNA and snoRNA
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 […]
What is the Difference Between Classical Alternative and Lectin Pathway
The key difference between classical alternative and lectin pathway is that the initiation of the classical pathway takes place through the binding of antigen-antibody complexes to the C1q protein, and the alternative pathway initiation takes place through the binding of C3b onto foreign surfaces, while initiation of lectin pathway takes place through mannose-binding lectin. The […]
What is the Difference Between Pneumococcal Vaccine and Flu Vaccine
The key difference between pneumococcal vaccine and flu vaccine is that pneumococcal vaccine is a type of vaccine against the bacterium Streptococcus pneumoniae while flu vaccine is a type of vaccine against the virus influenza. A vaccine is a biological preparation that protects people against infectious diseases by providing acquired immunity. The process of administration […]
What is the Difference Between Chemiosmosis in Mitochondria and Chloroplast
The key difference between chemiosmosis in mitochondria and chloroplast is that in mitochondrial chemiosmosis, the source of energy is food molecules, while the energy source for chemiosmosis in chloroplast is received by a light source. Chemiosmosis is the movement of ions from one side of a biological semipermeable membrane to another across an electrochemical gradient. […]
What is the Difference Between Runny Nose and CSF Leak
The key difference between runny nose and CSF leak is that runny nose is a medical condition that occurs when mucus is being discharged out of the nose due to colder outer temperatures, flu, or allergies, while CSF leak is a medical condition that occurs when cerebrospinal fluid leaks from a hole in the outermost […]
What is the Difference Between Hemophilia A and B and C
The key difference between hemophilia A and B and C is that hemophilia A is due to the deficiency of clotting factor VIII, while hemophilia B is due to the deficiency of clotting factor IX and hemophilia C is due to the deficiency of clotting factor XI. Hemophilia A and B are due to an […]
What is the Difference Between Free PSA and Total PSA
The key difference between free PSA and total PSA is that free PSA is only the amount of freely floating prostate-specific antigen in the bloodstream while total PSA is the amount of both freely floating prostate-specific antigen in the bloodstream and the prostate-specific antigen bound to other proteins. Prostate-specific antigen (PSA), also known as gamma-seminoprotein […]
