What are some of the benefits of squeezing so much data into virtually every cell in the body?

Why did we not evolve with one central repository of DNA rather than having it replicated throughout the body?

Assume that the hereditary information carried in genes and DNA is responsible for a lot of the differences we observe in humans and other living things. How could just four different bases in DNA strands be responsible for the almost endless variety found in nature?

Solution Summary

1. Life emerges as a single cell, which is the result of the union of an egg and a sperm, with a single DNA strand. Such a DNA strand contains a complete representation of all aspects related to the physiology of a living organism. Squeezing such huge amount of data into each and every cell in the body has certain benefits such as autonomy and protection.

1. Life emerges as a single cell, which is the result of the union of an egg and a sperm, with a single DNA strand. Such a DNA strand contains a complete representation of all aspects related to the physiology of a living organism. It also contains information regarding the process of formation of the body of an organism by repeated cell divisions, starting from a single cell. Each cell will be provided with information regarding when it should split into two identical cells, split into different kinds of cell in order to enable tissue differentiation, cease to grow when the body or a particular organ reaches maturity, and grow afresh in order to replace the lost tissue due to injury. The complete information regarding all the above mentioned aspects is encoded into a single molecule. Squeezing such huge amount of data into each and every cell in the body has certain ...

  • Isolating DNA

    Thymine and cytosine (pyrimidines) are single ringed nitrogen bases which are linked to sugar by using nitrogen present at 1 ' -position. Adenine, Guanine and Cytosine are found in DNA and RNA while Thymine is only found in DNA.

  • Discuss different models for DNA replication that were considered by early researchers.

    However in the conservative version, it was believed that the two parents' strands found each other and formed a helix after the strands were replicated. Same for the daughter strands.

  • DNA is molecule of heredity

    The structure showed that the DNA is a double-helix with two complementary strands, chemically stable, simple enough to function a code for life, and its bases were in agreement with Chargaff's observations that molar base ratios of A equal T and G equal

  • How does DNA turn into amino acids?

    It is made of two strands of nucleotides that are linked together. Each nucleotide contains one of four nitrogen bases: A (adenine), C (cytosine), G (guanine), and T (thymine).

  • Propose an Experiment Similar to Mesleson-Stahl

    This isotope is inserted into nitrogen bases which then incorporates into newly synthesized DNA strands. After two or three cell divisions, the DNA of the cells will be labelled with heavy isotope.

  • Transmission of Genetic Material

    DNA replicates in the nucleus of the cell. An enzyme breaks the hydrogen bonds between the two strands of the double helix. When the nitrogen bases are exposed, free-floating nucleotides in the nucleoplasm attach themselves to the exposed bases.

  • DNA Replication Models

    By centrifugation, they found the E.coli had DNA containing the heavy nitrogen 15N appeared as a single band when grown in 15N medium for several generation.

  • DNA Structure

    What would these bases be transcribed into if making a piece of mRNA from this DNA? 5) In tutorial C, erase the bases and the H (hydrogen) bonds. (See light blue box at the bottom of the tutorial.) You are left with the phosphates and the sugars.
