Answer:
Fingerprints are still the most cost-effective and reliable way to identify people: ... No two fingerprints have ever been identical in the many millions of comparisons. Fingerprints solve ten times more unknown-suspect cases than DNA fingerprinting.

<h2>Answer</h2>
The plasma membrane is made up of a phospholipid bilayer, with the <u>Hydrophilic</u><u> </u><u>Heads</u> of the phospholipids <u>sticking out toward the interior and exterior of the cell</u>.
- <u>The hydrophilic polar head of the phospholipid is attracted to water, while the hydrophobic tails are excluded by water.</u>

There are four main groups of organic molecules<span> that combine to build cells and their parts: carbohydrates, proteins, lipids, and nucleic acids. So it would be C. Lipids</span>
False, Some plasmids may reanneal without taking in any more DNA. when plasmid and foreign DNA are combined after being cut with the same restriction enzyme
Enzymes that cleave DNA are known as restriction enzymes. Each enzyme distinguishes one or more target sequences and cleaves DNA at or close to those sequences.
Numerous restriction enzymes produce single-stranded DNA overhangs at the ends of their cuts, which are often staggered. But some result in blunt endings.
DNA ligase is an enzyme that joins DNA. A single, unbroken DNA molecule can be created by joining two sections of DNA that have matching ends using ligase.
DNA ligase and restriction enzymes are employed in DNA cloning to splice genes and other DNA fragments into plasmids.
An enzyme that cuts DNA and recognises particular DNA locations is known as a restriction enzyme. A number of restriction enzymes make staggered cuts at or near their recognition sites to create ends with a single-stranded overhang.

This is because maybe that allele for the trait is recessive and the person is heterozygous.
If the person is heterozygous, it means that they have both the dominant and recessive allele for a trait. And by dominant and recessive, if dominant allele exists, no matter if recessive allele exists or not, the characteristic controlled by the dominant allele must be shown. This is their phenotype, which is the observable characteristics.
For example, there are 2 alleles for controlling the eye color. Brown allele is dominant, while blue is recessive. Just like the question above, if the person has an allele for blue eye color, but they have the brown color allele too, their phenotype would be brown eye color, as the brown color is dominant over blue eye color. This matches the requirements of having the allele for a particular trait but not showing the phenotype of that.
