Rough Endoplasmic Reticulum

Rough Endoplasmic Reticulum The rough endoplasmic reticulum (ER rough) is part of the cell’s endomembrane system and a subset of the endoplasmic reticulum (ER). This organelle is mainly concerned with the synthesis, folding, and modification of proteins, especially those that have to be delivered to different organelles within the cell or secreted by the cell. … Read more

The decline of insects

The decline of insects In recent decades, a certain awareness has been created about an everyday phenomenon that could have serious environmental consequences: insects that hit the windshield of our cars. Or, to be more exact, the fact that the number of insects hitting the windshield has drastically decreased. It is common knowledge that years ago the windshields were … Read more

Sanger sequencing method

Sanger sequencing method In a previous article on the Human Genome Project, we talked about the feat of obtaining the complete sequence of our genome, as well as its applications. For this, it was necessary to determine the order of the nucleotides that make up DNA , which required a considerable effort on the part of several universities and research … Read more

What is CRISPR, the technique that will change genetic manipulation?

What is CRISPR, the technique that will change genetic manipulation? What is CRISPR? These are DNA sequences that contain a multitude of palindromic segments, that is, sequences that are read in the same way in both directions of the DNA strand. These palindromic segments are divided by spacer sequences and there is also a “leader” sequence. The set of the palindromic, … Read more

What is a dominant gene and a recessive gene?

What is a dominant gene and a recessive gene? The transmission of characters between parental organisms and their offspring is a complex and fascinating subject. The first person to carry out an analytical investigation of this matter was the monk Gregor Mendel in the 19th century, without knowing what a gene was. Mendel became famous for his … Read more

Human Genome Project: what is it and what applications does it have?

Human Genome Project: what is it and what applications does it have?

Human Genome Project: what is it and what applications does it have? The first genetic studies date back to the 19th century, long before we knew what genes were. By growing peas ( Pisum sativum ) with different characteristics, the Augustinian monk Gregor Mendel was able to elaborate on the so-called laws of inheritance, which describe how some characters are … Read more

Deforestation: definition, causes, consequences, and types

Deforestation: definition, causes, consequences and types. Deforestation is one of the most mentioned concepts when talking about endangered or extinct species, threats to biodiversity, and an important factor that can increase the problem of global warming. But… what are we talking about when we talk about deforestation? Below we will answer this question and others such as … Read more

What is exocytosis? Exocytosis mechanism

What is exocytosis? As compared to endocytosis, exocytosis is a process that is used to use energy to move materials from inside the cell to the outside of the cell. Therefore, it is a kind of active transport mechanism and the opposite of endocytosis. Generally, in this exocytosis mechanism, a special vesicle attached to the cell … Read more
