Genetics of Speciation02:16

Genetics of Speciation

21.1K
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.

Physiological Barriers01:25

Physiological Barriers

5.2K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

    Area of Science:

    • Genomics and molecular biology
    • Epistemology and philosophy of science

    Background:

    • Traditional genomics aimed for precise predictability from DNA sequences.
    • Biological causation is increasingly understood as more complex than additive models suggest.

    Purpose of the Study:

    • To explore the implications of genomic complexity for scientific understanding.
    • To highlight the shift from linear to interactive models in genomics.

    Main Methods:

    • Analysis of current genomic data and literature.
    • Philosophical inquiry into the nature of biological knowledge.

    Main Results:

    • Genomic data reveal a higher-dimensional, interactive, and fluid genomic landscape.
    • This complexity challenges the notion of simple, additive predictability from DNA.

    Conclusions:

    • The inherent fluidity of the genome necessitates new epistemological and ontological frameworks.
    • Accepting this complexity can drive innovation in biological sciences.
