The key difference between agar and agarose is that the agar is a gelatinous substance obtained from red algae while the agarose is a linear polymer purified from agar or red seaweeds. Agar and agarose are two kinds of polysaccharide products that come from red algae or seaweed. They are very useful in a variety […]
Difference Between Bacteria and Viruses
The key difference between bacteria and viruses is that the bacteria can live without a host organism while the viruses cannot live without a living host. Many people think that both bacteria and viruses are germs that are harmful to human beings. Furthermore, they think that viruses and bacteria belong to the same category that […]
Difference Between Plants and Animals
The key difference between plants and animals is that the plants cannot move and they stay attached to the soil by roots while the animals can move from place to place. Also, the plants contain chloroplasts and chlorophylls but not the animals. Scientists tried to classify living organisms using different techniques. As a result, Robert […]
Difference Between a Ribonucleotide and a Deoxyribonucleotide
The key difference between a ribonucleotide and a deoxyribonucleotide is the sugar component of each nucleotide. Ribose is the sugar component of ribonucleotides while deoxyribose is the sugar component of deoxyribonucleotide. RNA and DNA are polymers of nucleotides; they are ribonucleotides and deoxyribonucleotides respectively. Though all human beings are alike in the sense that they […]
Difference Between Codominance and Incomplete Dominance
The key difference between codominance and incomplete dominance is based on the expression of the traits in the offspring. In Codominance, the offspring receive a combination of both parent genes, whereas, in Incomplete dominance, neither one of the parent genes expresses. In genetics, Gregor Mendel discovered the Principal of Dominance. But, it was found that […]
Difference Between Gram Positive and Gram Negative Bacteria
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 […]
