Answer:
B. The smaller DNA pieces travel farthest towards the positive end of the box
Explanation:
Gel-electrophoresis technique is a technique which is used to separate the fragments of DNA based on their size. The technique is employed in the DNA fingerprint analysis.
The DNA samples are loaded on one side of the gel and when an electric current is applied, the DNA moves from the wells towards the electrodes.
The DNA is a negatively charged molecule which travels through pores in the gel and reaches towards the electrode with positive charge.
The smaller the size of the DNA fragment, the faster it moves.
Thus, Option-B is correct.
The answer is <span>c. Branched polymers.
</span><span>Polymer is a large
molecule formed by joining several monomers. The simplest polymers are linear polymers which have no branches. But, some polymers have many start point and end points known as branches, so those polymers are called branched polymers. They could be star polymers, brush polymers, comb polymers, etc.</span>
A haploid cell formed in the male testes is the correct answer
Answer:
Without Earth's magnetic field, solar winds — streams of electrically charged particles that flow from the sun — would strip away the planet's atmosphere and oceans. As such, Earth's magnetic field helped to make life on the planet possible, researchers have said.
Explanation:
Hope this helps.
