This either attaches the virus to the host cell or dissolves the membrane letting the virus into the host cell. The viral enzymes(enzymes are again chemical compounds) multiply the viral dna copies and viral protiens. These are new viruses. These new viruses breakout of the cell to infect other cells.
Carbohydrates, lipids, proteins, and nucleic acids
I
assume the question asks for the number of phenotypes present.
The
phenotype is the set of visible characteristics of an individual resulting
from the interaction of its genotype. In this case, the number of phenotype is
the total number of combinations of the characteristic purple or white and
wrinkled or smooth:
<span>purple
and smooth
white and smooth
purple and wrinkled
white and wrinkled</span>
<span>So
basically there are 4 phenotypes. (ANSWER)</span>
Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
