Anonymous users2024-02-06The mitochondrial genome is also called mitochondrial DNA (mtdna). The mtDNA structure is similar to that of bacterial DNA, in a double-stranded circular shape. The structural characteristics of the mitochondrial genome are also the same as those of prokaryotes.
mtDNA can independently encode some proteins in mitochondria that are extranuclear genetic material. Genome is a general term for DNA and its protein complexes that cells carry information about life.
The mitochondrial genetic system does have many characteristics similar to those of bacteria, such as: DNA is a circular molecule with no introns; Ribosome.
for the 70s type; RNA polymerase is inhibited by ethidium bromide but not by actinomycin D; tRNA and aminoacyl-tRNA synthetase are different from those found in the cytoplasm; The initiating aminoacyl tRNA for protein synthesis is N-formylmethionyl tRNA, which is sensitive to chloramphenicol, an inhibitor of bacterial protein synthesis, and insensitive to cycloheximide, an inhibitor of cytoplasmic protein synthesis. In addition, mammals.
The genetic code of mtDNA differs from the generic genetic code in the following ways: UGA is not a termination signal, but tryptophan.
passwords; Peptides.
Methionine inside.
It is encoded by two codons, AUG and AUA, and the initiating methionine is encoded by four codons: AUG, AUA, AUU and AUC. AGA, AGG is not arginine.
There are 4 stop codons (uaa, uag, aga, agg) in the mitochondrial cryptography. mtDNA is inherited in the maternal line. It has a higher mutation rate than nuclear DNA and lacks the ability to repair.
Some genetic diseases, such as Leber hereditary optic neuropathy and myoclonic epilepsy, are associated with mitochondrial gene mutations.

Rationality ** (REBT) was founded by the American psychologist Albert Ellis in the 50s of the 20th century. The overall model of rational emotion is "ABCDE", which is based on Ellis's "ABC Theory". He believes that people's emotional and behavioral disorders are not directly caused by a certain provocative event, but due to the belief that the individual who experienced the event is incorrect in its perception and evaluation, and finally leads to the emotional and behavioral consequences in a specific situation, which is called ABC theory. >>>More
The Mediterranean climate is characterized by westerly winds in winter, frequent frontal cyclone activity, mild climate, average temperature between 4 10 in the coldest month, and abundant precipitation. In summer, under the control of the subtropical high pressure, the air flow sinks, and the climate is hot and dry, with few clouds and abundant sunshine. >>>More
The so-called heredity, simply put, is the embodiment of the signs of the previous generation in the next generation through the genes in the DNA. Due to the dominant and recessive nature of chromosomes, there is generational inheritance and intergenerational inheritance. From clinical statistics, vitiligo has a certain hereditary nature, but the proportion is small, accounting for only about 4% of the incidence of vitiligo, which is only the existence of vitiligo, environment, mental status, work type, lifestyle in the incidence of vitiligo has its important influence.
