Which antibiotic would you use to determine if the recombinant dna was taken in?

1 answer:

6 0

Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.

Identify the rectangular solid that represents the cell with the smallest amount of plasma membrane per volume of cytoplasm

Xelga [282]

Answer:

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

<em>Note: The question is incomplete. The attachment below gives the complete question</em>

Explanation:

The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.

The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.

From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:

Solid 1: 10/2 = 5 cm⁻¹

Solid 2: 12.18/2 = 6.09 cm⁻¹

Solid 3: 19.0/2 = 9.5 cm⁻¹

Solid 4: 34.24/2 = 17.12 cm⁻¹

Solid 5: 65.79/2 = 32.895 cm⁻¹

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
