Where does gene splicing occur? Splicing occurs in the nucleus before RNA migrates to the cytoplasm. Once splicing is complete, mature mRNA (which contains uninterrupted coding information) is transported to the cytoplasm where ribosomes translate mRNA into protein. Pre-mRNA transcription contains both introns and exons. When and where does splicing occur? For genes encoded by … Read more
What is PCR and why is it used? Is PCR used in molecular biology to make many copies of (amplify) small sections of DNA? or a gene ?. By PCR it is possible to generate thousands or millions of copies of a particular section of DNA from a very small amount of DNA. PCR is … Read more
How is copper sulfate rehydrated? Heat the crucible on the bunsen burner while stirring the copper sulphate with the scoopula. It will take about 5 minutes to get out of the water. Dry copper sulphate tends to stick to the sides of the crucible and must be moved to dry effectively. What happens when you … Read more
What is the average wave height of a tsunami? Most tsunamis cause the sea to rise no more than 10 feet (3 meters). The Indian Ocean tsunami caused waves of up to 9 meters (30 feet) in some places, according to news reports. Elsewhere, witnesses described a rapid rise in the ocean. Floods can extend … Read more
Where do you find stromatolites? Stromatolites, also known as layered rocks, form in shallow water when biofilms of living microorganisms, such as cyanobacteria, trap sediment. Most stromatolites grow in extremely salty lagoons or bays, in places such as Australia, Brazil, Mexico and the Bahamas. Where can stromatolites be found? Ancient fossil stromatolites (3 million years … Read more
What proteins are in the cell membrane? Proteins are the second major component of plasma membranes. There are two main categories of membrane proteins: integral and peripheral. Image of a single-step transmembrane protein with a single alpha helix spanning the membrane and a three-step transmembrane protein with three alpha helices spanning the membrane. What are … Read more
What tree is this app? Is there an application that can identify trees? This ingenious new mobile application eliminates conjecture to identify different plant species. Described as Plant Shazzam, Plantsnap allows you to identify plants, flowers and trees by simply taking a picture of the plant on your phone. Can Google identify trees? There are … Read more
How do proteins relate to DNA? Each DNA sequence that contains instructions for making a protein is known as a gene. To perform these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our body. How do … Read more
What is the purpose of cultural mapping? Cultural mapping provides “an integrated picture of the character, importance, and cultural functioning of a place” to help communities recognize, celebrate, and support cultural diversity for economic, social, and regional development. Why is cultural mapping important? Cultural cartography has been recognized by UNESCO as a crucial tool and … Read more
How is coal formed from dead vegetation? What is this process called? This process is called carbonization. Thus, carbonization can be defined as the slow process in which dead plants and trees below the surface of the earth at high pressure and temperature form coal. How is coal formed from dead vegetation? Coal is formed … Read more
