What are the advantages of discovery learning?
The Discovery Learning Model Key Advantages And Drawbacks It encourages motivation, active involvement, and creativity. It can be adjusted to the learner’s pace. It promotes autonomy and independence. It ensures higher levels of retention.
What is the most significant discovery in the last 10 years?
1. Higgs boson. It took four years, thousands of people and the world’s biggest machine, but, in 2012, particle physicists at CERN announced the discovery of the Higgs boson. The particle helps explain why all other particles in the universe have mass, and its discovery completed the standard model of particle physics.

What did NASA discover today?
A team of transatlantic scientists, using reanalyzed data from NASA’s Kepler space telescope, has discovered an Earth-size exoplanet orbiting in its star’s habitable zone, the area around a star where a rocky planet could support liquid water.
Who is discovered of DNA?
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
Who is the father of DNA?
James Dewey Watson
Who is the father of genetic code?
Marshall Nirenberg
What are three uses for DNA?
Common Uses for DNA Extraction
- Forensics. You likely know that DNA is a key component in many criminal investigations.
- Paternity Tests. DNA extraction is also helpful for determining the paternity of a child.
- Ancestry Tracking.
- Medical Tests.
- Genetic Engineering.
- Vaccines.
- Hormones.
How is DNA being used today?
Today, DNA identity testing is widely used in the field of forensics and paternity identification. Finally, DNA identity testing can be used to evaluate tumor transmission after transplantation and thus determine whether a malignancy is of donor or recipient origin.
How accurate is DNA fingerprinting?
DNA fingerprinting is extremely accurate. Most countries now keep DNA records on file in much the same way police keep copies of actual fingerprints. It also has medical uses.
Can you see DNA?
Given that DNA molecules are found inside the cells, they are too small to be seen with the naked eye. While it is possible to see the (containing DNA) using a light microscope, DNA strands/threads can only be viewed using microscopes that allow for higher resolution.
What does pure DNA look like?
DNA is a water-soluble acid, and the usual extraction process results in something that looks to the naked eye like clumps of very thin, limp noodles — or soggy cotton candy — floating in the tube.
Has DNA been photographed?
On 6 May 1952, at King´s College London in London, England, Rosalind Franklin photographed her fifty-first X-ray diffraction pattern of deoxyribosenucleic acid, or DNA.
What Colour is DNA?
Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5′ side of the sugar (indicated by light gray). Opposite to the 5′ side of the sugar molecule is the 3′ side (dark gray), which has a free hydroxyl group attached (not shown).
Is there life without DNA?
DNA is a fancy form of RNA. Some viruses and some bacteria have RNA instead of DNA for their coding material. There is no life without RNA. The RNA or DNA has two jobs, 1) to make an exact copy and 2) to make the proteins that make the body of the being.
What does DNA look like to the human eye?
What does a test tube of DNA look like? A. Under a microscope, the familiar double-helix molecule of DNA can be seen. Because it is so thin, DNA cannot be seen by the naked eye unless its strands are released from the nuclei of the cells and allowed to clump together.
What would happen if DNA get damaged?
The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues—including cancer. Fortunately, your cells have ways of fixing most of these problems, most of the time.
