Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.

<h3><u>Explanation:</u></h3>

The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated,  plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the  membranes of the cell.

The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.

Bess [88]

In this case, the physiotherapist is using Constraint-induced movement therapy.

In Constraint-induced movement therapy, the therapist forces the use of the affected arm, by restricting the movement of the arm. In this condition, the therapist block all the possible to work with an unaffected arm, which force the person to use the other arm, and hence, it helps in restoring the movement of the affected arm.

How many dna molecules are present in a synapsed pair of homologous chromosomes?
uranmaximum [27]

Answer:

The answer is 4

Explanation:

The answer is 4 because we are talking about pairs of homologous chromosomes and there  two copies  are held together and they are located in the centromere.

Synapsis is two homologous chromosomes pairing. During the event of <em>meiosis </em>homologous chromosomes are being pared but then also separated because of reducing the genetic content of the resulting haploid cells.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
