Answer:
Nucleus
Explanation:
Chromatids are the linearly arranged condensed structure of genetic material in the cell. The chromatids are observed after the parent cell are divided into the daughter cells.
During cell division, the cell divides, their chromosomes separate and gets accumulated at the poles of the cell. These chromatids are naked that is floating in the cytosol but the characteristics feature of the eukaryotic cell is the presence of a double membrane organelle which can protect the genetic material called the nucleus.
Thus, nuclear envelope or nucleus gets reformed around the chromatids.

Answer:
The smallest size tube that will hold the entire reaction is 0.5ml
Explanation:
25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total
since 1000ul=1ml, then 500ul = 0.5ml
Answer:
The device that mostlikely would not be used P20
Explanation:
P20 is a pipette used to measure and sample volumes of 20ul maximum.
Answer:
The reaction mix will have 400 units of the enzyme.
The working dilution will be 0.8 Units/ul.
Explanation:
The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.
Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.
