Genetics of Speciation02:16

Genetics of Speciation

21.0K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

What is Population Genetics?

64.7K
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.

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.2K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

30.7K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

64.0K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

  • To explore potential for developing targeted therapeutic interventions.

Main Methods:

  • Development of sophisticated genetic systems for S. pyogenes.
  • Construction of loss-of-function, conditional, hypomorphic, and gain-of-function mutations.
  • Application of these tools to interrogate gene/phenotype relationships.

Main Results:

  • Advanced genetic tools enable targeted gene modification in S. pyogenes.
  • These tools allow for hypothesis testing regarding gene function in pathogenesis.
  • A mechanistic understanding of virulence factor contributions is becoming feasible.

Conclusions:

  • Genetic manipulation tools provide a platform for studying S. pyogenes gene functions.
  • This research can lead to improved understanding of streptococcal diseases.
  • Advances may enable the development of novel therapeutic strategies against S. pyogenes infections.
