The key difference between interstitial and appositional growth is that interstitial growth is the longitudinal growth of bone which increases the length of the bone while appositional growth is the bone growth which increases the diameter of the bone. Bones can grow. They can increase in length as well as in diameter or thickness. Moreover, […]
Difference Between CCR5 and CXCR4
The key difference between CCR5 and CXCR4 is their role in HIV infection. During the early stages of HIV infection, viral isolates tend to use CCR5 for viral entry; hence M-tropic virus strains predominate during the early phase of infection. In contrast, the later isolates tend to use CXCR4 for viral entry; hence T-tropic virus […]
Difference Between Nicotinamide and Nicotinamide Riboside
The key difference between nicotinamide and nicotinamide riboside is that nicotinamide is an aryl amide compound containing the –C(=O)NH2 functional group whereas nicotinamide riboside is a chemical compound made from the combination of nicotinamide molecule with a ribose sugar molecule. Nicotinamide is a form of dietary supplement that we can consider as a form of […]
Difference Between Collagen Elastin and Reticular Fibers
The key difference between collagen elastin and reticular fibers is that collagen fibers are the most abundant type of fibers in the extracellular matrix of connective tissues while elastin fibers are tiny fibers that can stretch and recoil and they are found in elastic tissues. Meanwhile, reticular fibers are highly branched fibers which form a […]
Difference Between Amacrine and Horizontal Cells
The key difference between amacrine and horizontal cells is that amacrine cells receive information from the bipolar cells while horizontal cells receive information from photoreceptors. Photoreceptors, bipolar cells, ganglion cells, horizontal cells and amacrine cells are the five types of neurons found in our retina. All these neurons contribute to the processing of visual information in […]
Difference Between G1 G2 and S Phase
The key difference between G1 G2 and S phase is the growth that occurs. During the G1 phase, the cell shows first growth by copying organelles and making the molecular building blocks which are necessary for later steps; during the G2 phase, the cell shows second growth by making proteins and organelles and beginning to […]
Difference Between Gametic Sporic and Zygotic Meiosis
The key difference between gametic sporic and zygotic meiosis is that gametic meiosis is the meiosis that occurs during the formation of male and female gametes while sporic meiosis is the meiosis that occurs during the sporogenesis and zygotic meiosis is the meiosis that occurs in the zygote. Most life cycles include both haploid and […]
Difference Between Connective Tissue Proper and Specialized Connective Tissue
The key difference between connective tissue proper and specialized connective tissue is that connective tissue proper consists of loose connective tissue and dense connective tissue while specialized connective tissue consists of reticular connective tissue, adipose tissue, cartilage, bone, and blood. There are four basic types of tissues in the animal body. Connective tissue is one of these types and it is […]
Difference Between Quiescent and Senescent Cells
The key difference between quiescent and senescent cells is that quiescent cells are in the reversible G0 state while senescent cells are in the irreversible G0 state. Generally, a cell cycle has G1, S, G2, mitosis (nuclear division) and cytokinesis. Actively dividing cells undergo all these stages, and it is known as a replicative cell […]
Difference Between Keratinized and Nonkeratinized Epithelium
The key difference between keratinized and nonkeratinized epithelium is that keratinized epithelium is impervious to water while nonkeratinized epithelium is pervious to water. Based on the presence of keratin protein, there are two types of epithelia as keratinized epithelium and nonkeratinized epithelium. Keratinized epithelium forms the epidermis of land vertebrates. Nonkeratinized epithelium lines the buccal […]
