Why do scientists extract RNA from cells? Why is RNA extraction so important? If only one strand of the DNA molecule is transcribed for a particular gene, why is the other strand needed? Why is it important that both strands have all the information?
Why is DNA considered a nucleic acid ? Why is the flow of information from DNA to RNA to protein? Do ribosomes create protein? Explain why RNA primers are used in DNA replication. What is the reason for representing nucleotides by nitrogenous bases while writing DNA or RNA ...
Deep-sea dragonfish are found in the deep seas, so scientists rarely get the time to study them in-depth. Also known as the shiny loosejaw, they've been spotted off the west coast of the U.S. and Canada, with sightings from as far north as British Columbia and down to Baja, Mexico...
Up until the 1990s, most outbreaks we found werein the same geographic location—the church picnic where everyone eats the same bad potato salad and calls in sick the next day. Then new technology enabled scientists to determine the various DNA fingerprints of food-borne bacteria, which were ...
Polymerase chain reaction (PCR) isa method widely used to rapidly make millions to billions of copies (complete copies or partial copies) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of it) to a large enough amount to study ...
Fungi have been companions of mankind for millennia. Mushrooms inspired our eating culture, and yeasts and filamentous fungi were developed into highly efficient cell factories during the last 100 years to produce many products utilized in different indu
The nonfunctional "blueprints" written in the DNA get translated into protein (through an RNA intermediate, which we will neglect for the purpose of this article). Proteins are the functional agents that make biology go, and they are also functional tools that scientists need to do biological ...
How do we figure out which of these is the right one?Scientists use an approach called the scientific method. First, they observe or measure something (the sky being blue, for example) very carefully and systematically, which is known as gathering data. (When is it blue? Precisely what ...
The work could give scientists new ways to ask specific questions in cells, too. “We feel like we’re working on an important problem that could be significant for understanding how different diseases work and how they are impacted by changes in RNA methylation,” said Mugridge. ...
Why do retroviruses contain two identical RNA molecules? Why is it hard to isolate RNA as compared to DNA? a. How is RNA different from DNA and how it is similar? What is the usual role of RNA? of DNA? b. What are some of the reasons why many scientists think that lif...
