||Nucleus, mitochondria, chloroplasts
||Nucleus, ribosomes, cytoplasm, mitochondria, chloroplasts
||Double unbranched linear polymer, rolled with a right-handed spiral
||Single polynucleotide chain
|The composition of the nucleotide a
||Nitrogen base (purine-adenine, guanine, pyrimidine – thymine, cytosine); deoxyribose (carbohydrate); phosphoric acid residue
||Nitrogen base (purine-adenine, guanine, pyrimidine-uracil, cytosine); ribose (carbohydrate); phosphoric acid residue
|Types of Nucleides
||Adenyl (A), guanyl (G), thymidyl (T), cytidyl (C)
||Adenyl (A), guanyl (G), uridyl (T), cytidyl (C)
||Able to self-doubling by the principle of complementarity A = T, T = A, G = C, C = G Stable.
||Not capable of self-doubling. Labile.
||The chemical basis of the chromosomal genetic material (gene); DNA synthesis, RNA synthesis, protein structure information.
||Information (mRNA) – transmits a code of hereditary information about the primary structure of the protein molecule, ribosomal (rRNA) – is part of the ribosomes; transport (tRNA) – transfers amino acids to ribosomes; mitochondrial and platid RNA – are part of the ribosomes of these organelles
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
