The right answer is a person has more than two alleles for a certain trait.

Duplication is a genetic mutation characterized by the doubling of genetic material on a chromosome. There are several mechanisms that result in the duplication of either a large chromosomal portion, a gene, or a nucleotide sequence.

Create a table in which you compare the components and functions of the following.
Sauron [17]

Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.

  • Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.

Basic elements:

  1. Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
  2. Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
  3. Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
  4. Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)

Monomer constituents:

  1. Nucleic acids: nucleotides
  2. Proteins: amino acids
  3. Carbohydrates: monosaccharides
  4. Lipids: fatty acids and glycerol

Functions:

  1. Nucleic acids: contains the hereditary information to synthesize proteins
  2. Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
  3. Carbohydrates: store energy (short term); form cellular structures
  4. Lipids: store energy (long term); the main component of biological membranes

Examples:

  1. Nucleic acids: DNA and RNA
  2. Proteins: lactase; collagen
  3. Carbohydrates: starch (polysaccharide); glucose (monosacharide)
  4. Lipids: phospholipids; cholesterol

Give two reasons why dna evidence analysis is an imperfect science
Virty [35]

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.
