Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.0K
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...

lncRNA - Long Non-coding RNAs

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nursing Code of Ethics

4.3K
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

What is Population Genetics?

64.5K
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.

Area of Science:

  • Molecular Evolution
  • Genetics
  • Coding Theory

Background:

  • The origin of the genetic code is a complex problem in molecular evolution.
  • Known genetic code variants and their ancestry have been extensively studied.
  • Gonzalez et al. (2012) proposed a primeval mitochondrial genetic code (tessera code) with error detection capabilities.

Purpose of the Study:

  • To demonstrate the mathematical construction of the tessera code.
  • To link the tessera code to established coding theory and evolutionary models.
  • To provide a mathematical basis for the biological significance of the tessera model.

Main Methods:

  • Application of classical coding theory to construct the tessera code.
  • Demonstration of the tessera code as a linear coding of the standard genetic code.
  • Deduction of the tessera code from dinucleotide codes using Plotkin's construction.

Main Results:

  • The tessera code can be constructed using linear coding theory.
  • The tessera code is derivable from dinucleotide codes via Plotkin's construction.
  • The tessera model possesses a clear mathematical structure supporting its biological role.

Conclusions:

  • The tessera model of the mitochondrial genetic code has a sound mathematical foundation.
  • The mathematical structure reinforces the proposed evolutionary role of the tessera model.
  • This study bridges coding theory and molecular evolution to explain the genetic code's origin.
