All living organisms are made up of cells, which may appear in different shapes, sizes, arrangements and structures. At the same time, these cells may also adapt themselves to the organisms living environment as well as to its functional requirements….

Both plant and animal cells are eukaryotic, meaning their genetic material is enclosed within a nuclear envelope. They also share many organelles in common, including a cell membrane, mitochondria, ribosomes, endoplasmic reticulum, lysosomes, and Golgi apparatus. Both animal and plant…

Mitochondria are organelles found exclusively in eukaryotic cells, i.e. protozoa, fungi, plants, and animals. The term ‘mitochondrion’ is derived from a Greek word meaning thread. This accurately describes their appearance in the light microscope, as barely visible thread like structures. Following…

Humans can make ten of twenty of the amino acids in their own body. Since there is a lack of resources they can’t make the other ten. They must get these other amino acids from other animals and plants. Meaning…

The concept of DNA engineering (also known as DNA manipulation, DNA technology, and DNA recombination) is controversial, and the process of DNA engineering is amazing. DNA engineering is the altering of DNA, with the purpose usually being to mass produce…

The three most prominent roles of RNA are that of mRNA, tRNA and rRNA. Apart from these RNAs there is another class of RNAs referred as noncoding RNAs (ncRNAs) that perform a variety of functions such as in gene expression/regulation,…
