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
I would have to say (D.) if it's been 150 years.
Meiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1 (the only difference is that in meiosis, you're doing that for 2 cells to get 4).
<span>The Golgi apparatus </span>is responsible for packing proteins from the rough endoplasmic reticulum into membrane-bound vesicles which then trans locate to the cell membrane. At the cell membrane, the vesicles can fuse with the larger lipid bi layer, causing the vesicle contents to either become part of the cell membrane or be released to the outside.
