asymmetrical

Examples of asymmetrical in the following topics:

• Gene Expression in Stem Cells

  • Symmetric division maintains stem cell lines and asymmetric division yields differentiated cells.
  • To ensure self-renewal, stem cells undergo two types of cell division: symmetric and asymmetric.
  • An asymmetric cell division produces two daughter cells with different cellular fates.
  • This mechanism is known as extrinsic asymmetric cell division.
  • The term asymmetric cell division usually refers to such intrinsic asymmetric divisions.

• Body Plans

  • Animal body plans can have varying degrees of symmetry and can be described as asymmetrical, bilateral, or radial.
  • They can be asymmetrical, radial, or bilateral in form .
  • Asymmetrical animals are those with no pattern or symmetry, such as a sponge.
  • The sponge is asymmetrical, the sea anemone has radial symmetry, and the goat has bilateral symmetry.

• Animal Characterization Based on Body Symmetry

  • At a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical.

• Organic Enantiomers

  • Optical isomers are stereoisomers formed when asymmetric centers are present; for example, a carbon with four different groups bonded to it.

• Excavata

  • Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove "excavated" from one side.

• Selective Permeability

  • Plasma membranes are asymmetric: the interior of the membrane is not identical to the exterior of the membrane.

• Characteristics of Birds

  • Flight feathers are asymmetrical, which affects airflow over them and provides some of the lifting and thrusting force required for flight .

• Structures of the Heart

  • The heart muscle is asymmetrical as a result of the distance blood must travel in the pulmonary and systemic circuits.

• Amino Acids

  • Amino acids have a central asymmetric carbon to which an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group) are attached.

• Chromosomal Structural Rearrangements

  • A pericentric inversion that is asymmetric about the centromere can change the relative lengths of the chromosome arms, making these inversions easily identifiable.
