Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

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.
Gene Conversion02:08

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
Genome Copying Errors02:46

Genome Copying Errors

DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their  survival. Therefore, the copying errors are checked and repaired at three levels.

Inheritance01:25

Inheritance

Gregor Mendel's pioneering work on the principles of inheritance fundamentally transformed our understanding of how traits are transmitted from generation to generation. His experiments with pea plants laid the groundwork for the discovery of genes, discrete units within organisms that control heredity.
Each gene exists in pairs, and the combination of these genes from both parents forms an individual's genotype. This genotype is a blueprint of potential traits. Examples of genotype traits...

まとめ

核へのミトコンドリア遺伝子の移転は,アウトクロスする植物よりも,自生植物でより一般的です. これは,自己主義が遺伝子の組み合わせを保存し,転移を容易にし,アウトクロスがそれらを破壊することを示唆して,進化論に挑戦しています.

科学分野:

  • 進化生物学の進化生物学について
  • 遺伝学 遺伝学とは
  • 植物学は植物科学である.

背景:

  • 核へのミトコンドリアの遺伝子転送は,種によって異なります.
  • 現存する理論は,アウトクロッシングは,ミュラーのラチェットとより速い突然変異の広がりによる遺伝子転送を好むべきであると予測しています.

研究 の 目的:

  • 植物生殖モードと,機能的なミトコンドリア遺伝子の核への移植の発生率との関係を調査する.
  • 遺伝子の移転に関する現在の進化論に挑戦し,精錬する.

主な方法:
