In previous articles, we talked about the two types of cell division, mitosis, and meiosis. We also described the differences between the terms chromatin, chromosome, and sister chromatid. However, if at this point someone asked you to find the number… Continue Reading
Mitosis is a type of cell division that results in two daughter cells that are identical to each other and their parent cell as well. Mitosis is an important process for many organisms since it serves different purposes. The zygote,… Continue Reading
Chromosomes, chromatin, nucleosomes, genes, alleles? What is the difference between these terms? What are their roles? And how are they organized inside each one of the small cells of an organism? When you hear these words, you might think that… Continue Reading
We learned in a previous post that in 1952, after a lot of experiments, DNA was accepted by the scientific community as the genetic material of the cells. However, something was still missing, and that was its structure. For many… Continue Reading
In a previous post, we learned that DNA is the genetic material of the cells, and one of its most important functions is that it contains genes that carry the information for the determination of the hereditary characteristics. However, scientists were… Continue Reading
DNA or Deoxyribonucleic acid is the genetic material of all the cells and most viruses, with the exception of some viruses that use another type of nucleic acid, called RNA or Ribonucleic acid. As we will see in the following… Continue Reading
Viruses are microscopic parasites whose size belongs to the nanometer scale. They can invade the cells of other organisms in order to reproduce, since they don’t have the ability to do that independently, outside of their hosts. You might be… Continue Reading
We have already talked about how eukaryotic and prokaryotic organisms organize their cells in order to carry out their functions in efficient ways. But how are the different cellular parts (or organelles in eukaryotes) formed and how do they carry… Continue Reading
