nucleus containing dna

. The membrane encloses a clear fluid matrix called nucleoplasm or karyolymph. It encloses a fine network of thread-like structures, called chromatin network. It is composed of chromatin that contain DNA and histones arranged in a specific manner. The chromatin condenses to form..

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 containsh..

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 mai..

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 a..

The complimentary property of the nucleotides of DNA has been proved to be the most powerful tool of genetic engineering. After cutting a segment of DNA or gene with the help of specific enzyme, it can be joined or attached with the DNA of a different organism. Such t..

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 ..

. According to this theory, Each adult organism grows from a zygote. The zygote is a diploid cell having two sets of chromosomes - maternal and paternal. The zygote by mitotic divisions results in the formation of an adult and thus, all the vegetative or somatic cells of an organism are diploid wit..

The head is almost conical in the human sperm. It is formed of an acrosome and nucleus enclosed in a thin membrane. The acrosome forms a cap at the anterior end of the nucleus. It is formed from the golgi complex. It secrets tissue - dissolving lytic enzymes called hyaluronidase..

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 in..
