do mitochondria contain dna

Mitochondria are tiny structures that occur in varying shapes cylindrical, spherical, oval, rod shaped etc. They are found distributed all over the cytoplasm. fig. 16.6 - Mitochondria Each mitochondrion is bound by a double membrane. The outer membrane is smooth and straight, wh..

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..

DNA molecule is a double helical structure made of deoxyribo nucleotides. RNA is also present in nucleus as well as cytoplasm. DNA is the major source of genetic information which is copied into RNA molecules (transcription). The sequence of nucleotides contains the '..

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 component of chromosomes. A small amount of DN..

A gel is immersed in a buffered solution, and then DNA fragments from individuals are added to the gel. When an electric current is applied to the solution, one end of the gel takes on a negative charge, and the other end a positive charge. DNA molecules carry a negative charge ..

The semi conservative DNA replication was confirmed by an elegant experiment conducted by M. Meselson and F. W. Stahl in 1958. They grew the bacterium Escherichia coli in a medium containing nitrogen salts labeled with the stable heavy isotope 1 5 N. 1 5 N was incorporated ..

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..

Organisms look similar because their body designs are similar. If body designs are to be similar, the blue prints for these designs should be similar. Thus, reproduction involves making copies of the blueprints of body design. The chromosomes in the nucleus of a cell contain information ..
