The key difference between gram positive and gram negative bacteria is that gram positive bacteria have a thick peptidoglycan layer, hence appear in purple colour while gram negative bacteria have a thin peptidoglycan layer, hence appear in pink colour at the end of the gram staining technique. Bacteria are ubiquitous prokaryotes which are unicellular and […]
Difference Between Transcription and Translation in DNA
The key difference between transcription and translation in DNA is that transcription is the production of an mRNA sequence which contains the genetic code encoded in the coding sequence of the gene while translation is the production of a functional protein using the genetic code encoded in the mRNA sequence. Gene expression is the process […]
Difference Between Sterilization and Disinfection
The key difference between sterilization and disinfection is that sterilization is a process of killing all forms of microbial life including the spores present in an object while disinfection is a process of reducing or removing harmful microorganisms from the inanimate objects and surfaces. Microorganisms are ubiquitous. Since they cause contamination, infection and decay, it becomes necessary […]
Difference Between DNA and RNA Structure
The key difference between DNA and RNA structure is that the DNA structure is a double helix composed of two complementary strands while RNA structure is single-stranded. Nucleic acids are macromolecules or biopolymers. Moreover, they are the building blocks of genetic material of an organism. They are comprised of nucleotide chains linked via phosphodiester bonds […]
Difference Between Eukaryotic Cells and Prokaryotic Cells
The key difference between eukaryotic cells and prokaryotic cells is that the eukaryotic cells possess a true nucleus and true membrane-bound organelles while the prokaryotic cells do not possess a true nucleus or true organelles. Cells are an essential part in the formation of everything that is around us. The composition of the cells can […]
Difference Between Direct Lifecycle and Indirect Lifecycle
The key difference between direct lifecycle and indirect lifecycle in the context of parasite reproduction is that, in the direct lifecycle, the simple parasite lives its lifespan and reproduces within a host once entered while in the indirect lifecycle, the complex parasites require many numbers of hosts during the completion of their lifecycles. Parasites are small […]
Difference Between Slow and Fast Twitch Fibers
The key difference between slow and fast twitch fibers is that the slow twitch fibers are the muscle fibers mainly used for long endurance such as distance running and they do not become tired easily while fast twitch fibers are the muscle fibers used for a powerful burst of movements such as sprinting and they […]
Difference Between Chlorophyll A and B
The key difference between chlorophyll A and B is that the chlorophyll A is the primary photosynthetic pigment in plants and algae while the chlorophyll B is an accessory pigment that collects energy and passes to chlorophyll A. Chlorophyll is a family of natural pigments that are present in plants and algae and is responsible […]
Difference Between Decomposer and Detritivore
The key difference between decomposer and detritivore is that the decomposer is a saprophytic organism which decomposes and recycles dead organic matter in the environment while detritivore is a type of decomposer which consumes decaying organic matter and digests within its body in order to break down and obtain nutrients. An ecosystem consists of all the […]
Difference Between Stem and Trunk
The key difference between stem and trunk is that the stem usually refers to the main structural axis of a plant while trunk usually refers to the main structural axis of a tree. Stem and trunk are two botanical names sometimes used in a similar sense. Strictly speaking, there is some difference between stem and […]
