Biology Fundamentals - E-book - ePub

The fundamentals of biology beam its searchlight on all thebasic principles contained in various aspects of life sciences, likerecombinant DNA, genetics, molecular biology and biochemistry. Via the in-depth study of these principles, humans canadequately understand all the basic mechanisms that life entailsand then find an anchor for his biological thinking andknowledge, which are all required for full understanding of thevarious challenges humans encounter in day-to-day lives.
Thesechallenges vary from problems with human environmentalquality, loss of biodiversity, diseases, and health. The basic chemical structures of living things relate a great dealto their physical structure. Various cell processes come to playalso to give the human being its structure and function as seenon the exterior. Cellular organizations are equally essential, ensuring one cell functions in its place without unwantedinterference with another cell and its function.
Living processesdepend heavily on various metabolic processes, and theseprocesses occur in animals and plants. Humans, being the chiefamong higher animals, remain the main focus and end point ofall biological studies. Cell division is an integral part of the fundamentals of biologysince it forms the basis on which living things grow anddevelop. Cell division equally forms the basis for genetics, and itis irreversibly associated with both sexual and asexualreproduction processes.
Genetics is more or less a new entrant into biological studies, and its details have reached an advanced stage in recent times, thanks to the many genetic technological processes developed inrecent times. Genetics opened human eyes to the processesand studies of evolution, and they are both intertwined andinseparable. To improve on knowledge related to biological studies, humanshave engaged in various laboratory activities and formulatedvarious hypotheses to give human make up a meaning.
Thelaboratory activities culminate to data collection andinterpretation, which gave both to inferences and conclusionpresented to the world in the form of visual, oral and writtenforms of communication. Research in the world of biology is anongoing process since many more secrets about this broad fieldof study are still left unfolded. Fundamentals of biology seek to study this course at the levelof the cell.
It involves in-depth investigation into cellularstructures and chemical processes. As hinted earlier, geneexpression, cell division, and cell metabolism are also integralparts of the study. The content is more or less about the basicconcepts of biology, which form the foundation on which allother biology-related fields of study are built. It must be statedwith emphasis that the study of the fundamentals of biology atcellular level deals squarely with the eukaryotic cell, which is theform of cell found in humans, animals, and plants.
However, mentions are also made about prokaryotes. Cell functions in plants and animals are regulated by variousmolecular processes, which are essential in all multi-cellularorganisms.
