stressed out red blood cells to create an environment where harmful malaria bacteria would not be able to thrive in. The cause was later isolated in 1956 by medical researchers as G6PD deficiency which is common in African and Mediterranean descents. G6PD is an enzyme that protects red blood cells from damage, and premature death. This means that the bodies of people with G6PD deficiency will be weaker against harmful bacteria, and with primaquine stressing the red blood cells, the body becomes…

mitochondrial lineages are maternal. Thanks to the study of the mitochondrial genome it revealed that all humans carried mitochondrial DNA in their cells that dated back to a single…

sweat composed of and what are two functions of sweat? Water, salts, urea, uric acid, amino acids, ammonia, sugar, lactic acid, ascorbic acid, and pheromones. Two functions are to regulate body temperature and rid body of waste. 12. Name two types of sweat glands and differentiate between the two. Eccrine and Apocrine sweat glands. The apocrine glands are slightly larger and produce a thicker and more odorous sweat. The eccrine glands are located over almost the entire body, the apocrine…

of a fetus/embryo. 2. Leydig cells • Leydig cells form and secrete testosterone. The testosterone is secreted in response to the lutenising hormone. Spermatozoa production is promoted by the testosterone secreted. The testosterone being secreted by the Leydig cells are important for the formation of secondary characteristics of the male. 3. The different pancreatic cells • One of the pancreatic cells is the exocrine gland. The exocrine gland secretes out different types of enzymes. The enzymes…

celled microscopic organisms with one strand of DNA. Their life includes consuming nutrients from their environment, growing, and then dividing into two cells. Bacteria are continuously growing and dividing. Bassler continues her discussion of bacteria by classifying humans as ninty to ninety nine percent bacteria. Humans have ten trillion bacteria cells in us or on us at any moment in time. Bacteria creates an invisible layer around our body that keeps harmful threats out so we can stay…

The human body is made up of thousands of cells, each with a defined genetic program that allows them to work synchronically to regulate the metabolic and physiological processes required by the organism. All cells die (not accidentally), because in old age or because they are Cell death by apoptosis plays a crucial role in tissue development and homeostasis. This process is carried out through mitochondrial permeabilization and the activation of caspases. The condensation of chromatin and the…

article, “US Panel Greenlights Creation of Male ‘Three-Person’ Embryos,” written by Sara Reardon, in order to learn more about this new technology. The SciShow video that I watched defined mitochondrial DNA as a set of genetic instructions within our cells. It is made up of 37 genes that are inherited only from our mother’s DNA, and as with the human genome, genetic mutations within the mitochondrial DNA are possible. A mother can easily pass any mitochondrial DNA mutations to her offspring.…

“the production of genetically identical organisms via somatic cell nuclear transfer. ‘Somatic cell nuclear transfer’ refers to the process in which the nucleus of a somatic cell of an existing (or previously existing) organism is transferred into an oocyte from which the nucleus has been removed.” (Pros and Cons of Human Cloning, 2017). There are three different types of cloning: gene, reproductive and therapeutic. Of the three types the ones that are under much debate is reproductive and…

Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

Comparison chart Replication Transcription Purpose The purpose of replication is to conserve the entire genome for next generation. The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry. Definition DNA replication is the replication of a strand of DNA into two daughter strands, each daughter strand contains half of the original DNA double helix. Uses the genes as templates to produce several functional forms of RNA Products One strand…
