Answer:
50% G+C will have a higher Tm
Explanation:
The Temperature of Melting (Tm) refers to the temperature at which 50% of double-stranded DNA (dsDNA) is changed to single-standard DNA (ssDNA). In the double helix of DNA, Adenine bases always pair with Thymine bases through two hydrogen bonds, whereas Guanine bases always pair with Cytosine bases through three hydrogen bonds. In consequence, a DNA molecule containing a higher GC content is more stable than another DNA molecule containing a lower GC content. The Tm can be calculated as follows = 2 °C(A + T) + 4 °C(G + C) = °C Tm (this equation is useful for oligonucleotides of 14 to 20 base-length).
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.
<span>Q1. Diamond, Q2. Diamond, Q3. The amount of light bending depends on angle and wavelength the light enters the substance and how dense the substance is, Q4. If the second substance is more dense than the first, the light ray bends towards the ‘normal’, if it’s less dense it bends away, Q5. In the swimming pool, when you look at a person’s body underwater they appear disjointed.</span>
Answer:
SIV or Simian immunodeficiency virus
Explanation:
It causes a disease in monkeys similar to AIDS and is closely related to HIV-2 of humans.
Answer:
Because it is a solid that has trapped air with the water molecules in cold temperature thus creating a hard solid.
