Answer:

How does PCR work? To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA. Next, an enzyme called "Taq polymerase" synthesizes - builds - two new strands of DNA, using the original strands as templates.

Which of the following describes prophase of mitosis?
tigry1 [53]

Answer:

Daughter chromosomes move toward opposite poles of the cell.

Explanation:

Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.

CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.

When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.

Two bacterial strains have the same genes for metabolizing carbohydrates, but one is wild-type for a regulatory inducer while th
klemol [59]

Answer:

b. The two bacterial strains have different phenotypes.

Explanation:

In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.

Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.

Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
