23andMe is advertised to the public as a beneficial not only to help us as people get closer to our ancestral past, which is somewhat pointless due to the fact we have no true meaningful connections to these pasts. But to also help us grasp a better understanding of what lies within us health wise, whether it be a genetic trait such eye color or ones risk for developing a type of defect. The company’s mission statement says it all in fact, “We are a mission-driven company with big dreams of…

Paracrine Signaling Signals that act locally between cells that are close together are called paracrine signals. Paracrine signals move by diffusion through the extracellular matrix. These types of signals usually elicit quick responses that last only a short amount of time. In order to keep the response localized, paracrine ligand molecules are normally quickly degraded by enzymes or removed by neighboring cells. Removing the signals will reestablish the concentration gradient for the signal,…

ichael explains his case in a creative way. He has Down syndrome when the chromosomes came to make him, a normal chromosome broke, the broken piece moved and struck onto another chromosome.Its called spontaneous translocation.No one knows why this happens or how to prevent it. He starts to talk like how he is like everyone else. All he does is learns things a different way. It takes him longer to process information and form his thoughts and communicate with others. He gets frustrated when…

That is how I think of Biology, the smallest thing like a cell can do some impressive things. Biology being the study of life gives us an endless reality of changing and learning the ways of life. Taking the smallest thing like a cell has the power to change everything. The cell’s power can be used for good or for bad. Cells have the capabilities to cure the most invasive diseases. Us humans, for instance, is such a complex organism cell growing, reproducing and then dying and starting all over…

digest the cell wall of bacteria. Bacteria have been increasingly gaining resistance to antibiotics and lysins have been used in animal models to control these specific bacteria. Scientists may need these lysins to stop bacteria from becoming more and more resistant to antibiotics. Bacteria is infected by bacteriophage when it inserts itself into the cell. The lytic system weakens the cell wall and this creates bacterial lysis. Due to this, the bacteriophage has a place to exit the cell…

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…

The ethics of gene manipulation proposes a rather complex debate because of opposing religious/individual takes on this issue. My position on this issue is “in-between” because this could be a fantastic advancement at rescuing a family from a harmful genetic disease passing on and advances in genetic engineering have and still could enable an abundance of people with infertility problems to start a family. Although, the negative impacts of gene manipulation remain vital, it violates a child’s…

The skin consists of three main layers including epidermis, dermis and subcutis that are responsible for its high turnover capacity in repairing different injuries. Similar to other tissues, the stem cells existed in skin tissue play an important role in regulating the balance between cell loss and cell division [22, 23]. siRNA therapeutics are potent alternative for skin regeneration due to their accessibility in the body [24]. Skin repair based on siRNA therapy have yielded promising results…

clone by the processes of artificial twinning and somatic cell nuclear transfer. While organisms such as hydras and coral use budding which is when a new organism grows off the body of the parent organism naturally until the new organism falls off and begins to fend for itself. The earliest form of artificial cloning began in 1885 with sea urchins. The cloning of the sea urchins was both a clone and a refutation of a current theory of cell biology. Scientists posited that the first combination…

Animal Cloning As new technology is developed, cloning becomes a higher discussed topic. Cloning is the process of producing similar populations of genetically identical individuals. Cloning has been seen a as a recent discovery but cloning has been happening in nature since the beginning of time. Common animals that clone naturally are starfish, bacteria, and even some plants. But cloning becomes a controversial topic when humans artificially make clones of animals that normally reproduce…
