Dihedral angle is the angle between two intersecting planes.

• It is measured in degrees or radians.

• The planes can be defined by three points on each plane.

• Dihedral angles are commonly used in geometry and crystallography.

• They are also important in aviation for determining the stability and control of aircraft.

• For example, the dihedral angle of an airplane's wings affects its roll stability.

Nonsense mutation results in a premature stop codon, while missense mutation changes a single amino acid in the protein sequence.

• Nonsense mutation leads to a truncated protein that is usually non-functional.

• Missense mutation can have varying effects on protein function depending on the location and nature of the amino acid change.

• Examples of nonsense mutations include cystic fibrosis and Duchenne muscular dystroph...read more

Amino acids are the building blocks of proteins. They contain an amino group, a carboxyl group, and a side chain.

• There are 20 different types of amino acids that can be combined to form proteins.

• Amino acids are essential for the growth and repair of tissues in the body.

• Some amino acids can be synthesized by the body, while others must be obtained through diet.

• Examples of amino acids include alanine, glycine, and l...read more

Replication is the process of copying genetic information from one DNA molecule to another.

• Replication occurs during cell division.

• It ensures that each new cell receives an exact copy of the genetic material.

• Errors in replication can lead to mutations and genetic disorders.

• Replication is a complex process involving many enzymes and proteins.

• Examples of replication include DNA replication and RNA replication.
