Sanger sequencing targets a specific region of template DNA using an oligonucleotide sequencing primer, which binds to the DNA adjacent to the region of interest. (There must be an area of known sequence close to the target DNA.)W In order to determin...
Stem cells are pluripotent, meaning that they can differentiate into any type of cell. This makes them incredibly valuable in medical research, however harvesting stem cells from embryos is highly controversial. The advent of induced pluripotent stem cells (iPSCs) was a major breakthrough, because...
When the DNA double strand unwinds into two strands, transcription can occur along one of them. This does so in a predictable way, as A in the DNA is transcribed into U in mRNA, C into G, G into C and T into A. The mRNA then leaves the DNA (and in eukaryotes, the nucleus; in...
But even these robust beasts pale in comparison to a microscopic animal that is one of the toughest creatures ever to exist. This tiny organism has been on Earth for around 600 million years, meaning it both existed before and outlived dinosaurs. It is so adaptable that it's basically indes...
Gene expression in eukaryotes can also be regulated translationally. Which of the following would happen when a small RNA binds to an mRNA? A. The mRNA is degraded. B. The ribosome is stalled by double-stranded RNA. C. The ribosome falls off the...
Genes | Meaning, Types & Function from Chapter 15 / Lesson 19 42K Understand the meaning of genes and know the types of genes. Discover what the purpose of a gene is. Understand what is meant by alleles and gene therapy. Related to this QuestionWhat...
If two enantiomers are similarly present, they are collectively referred to as a racemic mixture, a mixture that does not rotate polarized light because the other cancels the optical behavior of each enantiomer. In chemistry, an enantiomers from Greek (enantios) meaning opposite and (meros) ...
Glass is chemically inert. This picture shows the silica atom in white, which binds with the four oxygen atoms. Each oxygen atom binds with one silica atom. Glass does not make chemical bonds because it is so solid, and all the bonds are taken. You must almost force a bond with anything...
Complete transection of this vessel causes severe trauma and ocular inflammation, and wide- spread retinal infarction; permanent occlusion of this vessel does not correspond to CRA occlusion in humans, and even a temporary occlusion in rats probably causes more widespread injury. Hence, the degree ...
This has implications for the most beneficial uses of AI in drug-discovery projects. What does this mean for applications of AI in drug discovery? AI can, in principle, deliver all of the above aims: it can make decisions faster (predictions are faster than experiments) and more cheaply (...
