New variety DNA in our cells has been identified called i-motif inside cells. A mangled knot of DNA the i-motif has never been observed inside living cells. Deep within our cells lies our DNA. The direction in the DNA code, all 6 billion A, C, G and T letters, offers specific instructions on how our bodies are built and their functioning.
The epochal double helix shape of DNA has seized the public imagination since 1953 when James Watson and Francis Crick incredibly revealed the structure of DNA. But now it’s ascertained that small extensions of DNA persist in varying shapes in the laboratory atleast and scientists conjecture that these varying shapes might be the reason for how and when DNA code is read.
The novel shape looks exceedingly varied to the double-stranded DNA double helix. Associate Professor Daniel Christ said that when most of the people think of DNA they think of double helix. Whereas this new research evokes an entirely different DNA structure and could be of vital significance for the cells.
Associate Professor Marcel Dinger said that the i-motif is a four-stranded ‘knot’ of DNA. He also said that in the knot composition C letters on the same strand of DNA bind to each other. So this is a varied kind of double helix where letters on converse strand comprehend each other and where Cs attaches to Gs.
Albeit researchers have observed the i-motif formerly and have researched it in detail, it has only been observed in vitro.
