Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
Explanation:
Answer:
<h2>The virus is a bacteriophage that is reproducing the lysogenic cycle.</h2>
Explanation:
When bacteriophage infect the bacteria, it can enter one of two cycles i) lytic or ii) lysogenic cycle.
In lysogenic cycle, virus injects its genome into the bacterial chromosome, known as prophage and it replicates with bacrerial DNA. When conditions change, this prophage can remove itself from the bacterial DNA , and lysogenic cycle can change into lytic cycle.
Answer:
B. No
Explanation:
First, let's watch what it looks like when a population is not evolving. If a population is in a state called Hardy-Weinberg equilibrium, the frequencies of alleles, or gene versions, and genotypes, or sets of alleles, in that population will stay the same over generations (and will also satisfy the Hardy-Weinberg equation). Formally, evolution is a change in allele frequencies in a population over a very long period of time, so a population in Hardy-Weinberg equilibrium is not evolving.
