Gene Evolution - Fast or Slow?

8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

What is Population Genetics?

65.0K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Fast Fourier Transform01:10

Fast Fourier Transform

972
The Fast Fourier Transform (FFT) is a computational algorithm designed to compute the Discrete Fourier Transform (DFT) efficiently. By breaking down the calculations into smaller, manageable sections, the FFT significantly reduces the computational complexity involved. Direct computation of an N-point DFT requires N2 complex multiplications, whereas the FFT algorithm needs only (N/2)log⁡2N multiplications, offering a much faster performance.
The computational efficiency of the FFT becomes...

Area of Science:

  • Biomaterials science
  • Soft matter physics
  • Polymer chemistry

Background:

  • Mechanically induced disorder-order transitions are known in synthetic systems but lack persistence.
  • Biopolymer liquids are gaining attention, yet stimuli-responsive materials are underexplored.
  • Existing shear-induced ordered phases typically revert after stimulus removal.

Purpose of the Study:

  • To develop a biomaterial exhibiting persistent, shear-induced liquid crystalline phases.
  • To investigate self-ordering behavior in complexed biopolymer systems.
  • To explore the potential for recording information using mechanical stimuli.

Main Methods:

  • Complexation of anionic polypeptides with cationic surfactants.
  • Induction of isotropic-nematic transitions via mechanical shear.
  • Observation of persistent liquid crystal phases after shear cessation.
  • Utilizing water flow and finger pressing for self-ordering.
  • Birefringence readout for pattern analysis.

Main Results:

  • A novel biological fluid system exhibiting shear-triggered isotropic-nematic transitions was created.
  • The induced liquid crystalline state persisted after the cessation of mechanical stimulus.
  • Self-ordering was achieved through water flow and finger pressing.
  • Finger pressing induced complex patterns readable by birefringence, enabling fingerprint recording.

Conclusions:

  • This work presents the first biomacromolecule-based fluid with persistent, shear-induced liquid crystallinity.
  • The material demonstrates tunable self-ordering and pattern formation capabilities.
  • Potential applications include information recording and advanced biomaterials.
