DNA-The code of life

DNA- the master code


We all have heard about this mysterious molecules which makes us what we are, how we look, the shape of us, even our mentality! So let us know about what this molecule is and how it works. 
DNA(deoxyribonucleic acid) is a type of nucleic acid polymer which contains the codes which instructs the cells in our body what to do. It is worked out by protein machines and RNA messengers. The code of life consists of four letters- A, T, C, G. They are the nitogenous bases which form a variety of arrangements to form a meaningful protein code. You can compare it to a computer code consisting of 0's and 1's which form a variety of arrangements to form words and numbers.
The work of DNA is carried out by its three modes of action:
  1. Replication: It is a phenomenon by which DNA is duplicated so that its daughter cells can get the same amount of the code. It is the reason due to which every cell in our body have same DNA. 
  2. Transcription: It is part in which DNA is coded to its messenger RNA molecules which carries the instruction manual for synthesis of proteins. 
  3. Translation: It is the final process which results in the interpretation of the manual and forming the machines from them.

Eye color and Tyndall Effect

Image
According to wiki:"Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye iris and the frequency-dependence of the scattering light by the turbid medium in the stroma of the iris." Eye color often is the genetic trait that fascinates parents the most as a child develops. Will the child's eyes be black, brown, blue, gray, green, hazel or some combination of colors?  Human eye color originates with three genes, two of which are well understood. These genes account for the most common colors — green, brown, and blue. Other colors, such as gray, hazel and multiple combinations are not fully understood or explainable at this time. The pigmentation of the iris depends on the concentration of melanin in the iris pigment epithelium(located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma.The appearance of blue and green, a...

Sheep-human hybrid : Birth of a new chimera organism.

Image
Researchers from University of California have been successful in producing  a chimera organism from DNA of sheep and human.The main purpose of this experiment was xenogenic generation of new organs. It is meant to change the future of organ donation- body parts synthesized from genetically modified sheep to save millions of lives waiting for organ donation. The process used here is by the infusion of  human DNA in host (here sheep) embryo.It is based on the interspecies blastocyst complementation. The chimera DNA molecule is prepared using the CRISPR- Cas9 mediated genome editing of the zygote to disable the genes that are responsible for the production of the particular organ and then infusing with the complementary genes(from human pluripotent stem cells(hPSCs)) responsible for formation of the organs in humans.It results in a hybrid creature that's more than 99 percent sheep – but also a tiny, little bit like you and me. The human portion of the embryos created in th...

Icy materials in space could behave like liquids at low temperatures and under ultraviolet light, suggests new research

Image
" Interstellar ice is believed to be a cradle of complex organic compounds, commonly found within icy comets and interstellar clouds, in association with ultraviolet (UV) irradiation and subsequent warming. We found that UV-irradiated amorphous ices composed of H 2 O, CH 3 OH, and NH 3 and of pure H 2 O behave like liquids over the temperature ranges of 65 to 150 kelvin and 50 to 140 kelvin, respectively. This low-viscosity liquid-like ice may enhance the formation of organic compounds including prebiotic molecules and the accretion of icy dust to form icy planetesimals under certain interstellar conditions. " According to the researchers from Hokkaido University in Japan, when the deep space conditions are right, this particular type of ice can attract and hold dust and debris, starting off a chain reaction that ends up with something like Jupiter . "The liquid-like ice may help dust accrete to planets because liquid may act as a glue," says lea...
