Primates

The order of Primates is a group of Mammals which includes animals such as lemurs, gibbons, gorillas, chimpanzees, and among others, man. In this group of animals we can find species like the pygmy mouse-Lemur, which on average weighs about 50g, and gorillas, which can weigh about 175kg. They have relatively large brains, a sharp […]

Prophase

Concept of Prophase The term prophase designates one of the subphases of mitosis, characterized by the reorganization of the cytoskeleton, migration of centriole to opposite cell poles, the appearance of the mitotic spindle, condensation of chromosomes, fragmentation of nuclear envelope and disappearance of the nucleolus. Cell Cycle The cell cycle is the basis of all […]

Proteasome

Proteasome Concept The term Proteasome refers to a protein complex present in the cell cytosol that has proteolytic activity. It is in this complex where proteins are degraded. Cell and Proteasome During its life cycle, the cell needs to express innumerable proteins, since they are responsible for its most varied mechanisms and functions. Proteins are synthesized […]

Pure Line

A pure line is a population that originates through inbreeding or self-fertilization, descendants always equal to each other and to the progenitors […]

Quantitative Genetics

Quantitative Genetics definition Quantitative Genetics refers to the branch of Genetics that studies variation of a given quantitative characteristic in a given population. Quantitative Characteristics There are two types of characteristics in natural populations, those that have a continuous distribution and those that are distributed by classes. Being the most common the characteristics with continuous […]

Red blood cell

Red blood cell is the most abundant element in the blood and a highly specialized cell whose function is to transport oxygen from the lungs to the cells…

Ribosome

Ribosome concept The term Ribosome refers to large complexes composed of rRNA and proteins, present in the cell’s cytosol, where protein synthesis occurs. From DNA to Protein For its processes of growth and metabolism, the cell needs proteins. For this, this same cell makes use of the transcription to read the information stored and contained in […]

Seahorse

Although, at first, it may not seem that way, the seahorse is a fish. Its body has a peculiar shape and its head has resembles the head of a horse. Another curious feature is the way they swim, with the body almost upright, driven by quick movements of the dorsal fin. Its body is covered […]

Southern Blot

Southern Blot Concept Southern blot refers to a Molecular Biology technique through which it is possible to verify whether a specific DNA sequence (gene of interest) is present in the sample. The sample under analysis contains a complex mixture (entire genome of an organism). With this technique it is also possible to obtain information on the […]
