In this context, it is necessary to analyze in detail what is the similarity between mitochondria and chloroplasts

The study of biology in the school curriculum is given a lot of attention, but even more so in the specialized universities of the country. This is a developed science, including many branches related to the study of all life on the planet. Due to the large volumes of information and the possibility of applying their knowledge in practice, this science is very capacious. And the question of how to learn biology is increasingly being asked in schools and universities. It is proposed to solve it by optimizing the entire learning process

Understanding the fundamental foundations of the existence of life is impossible without a clear understanding of the transmission of hereditary information and its implementation. The storage of the body's genes is realized through chromosomes, in which different sections of DNA are packaged, encoding the primary amino acid sequence of a certain protein. And the implementation of genetic information and its transmission by inheritance is achieved through its copying. This process is called "transcription"

Namely: from the remains of plants, like peat, coal also originated. His education, according to Lomonosov, was due to several factors. Firstly, the remains of vegetation decomposed without the participation of "free air" (that is, without free access of oxygen). Secondly, there was a fairly high temperature regime
