does mitochondria have dna

. The inner membrane encloses a matrix, which is rich in proteins, lipids, ribosomes, RNA and one or two circular DNA molecules. The number of mitochondria in a cell varies considerably and depends on the mature of the cell. Cells with very high-energy requirements possess very ..

Nucleic acids are of two types. They are DNA and RNA. In higher cells, DNA is localised mainly in the nucleus within the chromosome. A small amount of DNA is present in the cytoplasm also it is contained in the mitochondria and chloroplas..

Deoxyribose Nucleic Acid (DNA) - With the exception of a few viruses, DNA forms the genetic material in all living organisms. In the prokaryotic cells DNA occurs in the cytoplasm. In the eukaryotic cells it is confined largely to the nucleus and forms the main componen..

>The homeostatic mechanisms work on a negative feedback. In order to ensure the continuation of species, all living organisms exhibit reproduction. The entire cellular information is stored in the DNA which undergoes replication to transfer the information to the successive generations. T..

DNA contains the information required for the synthesis of cells specific proteins. DNA is located in the nucleoid (prokaryotes) or nucleus (eukaryotes) and protein synthesis occurs in the cytoplasm. DNA does not move to the site of protein synthesis (r..

Transcription This is a process in which RNA is synthesized from DNA. Among the two strands of DNA one strand serves as template and is called as coding strand where as the other strand is called as non-coding strand as it does not participate in transcrip..

Mitosis - This type of cell division occurs in the somatic (body) cells. Here a diploid (2n) parent cell gives rise to two diploid (2n) daughter cells. For the purpose of description mitosis is divided into four stages - Prophase Metaphase Anaphase Telophase It is important to understand that Mitos..
