What is a gene (जीन क्या है)



What is a gene (जीन क्या है)


Gene genome ke bheetar   DNA ke chhote khand hote hain jo protein ke lie kod hote hain. unmen hamaaree vyaktigat visheshataon ke nirdesh hain - jaise aankh aur baalon ka rang.

Gene aur unke controlling vaale switch DNA se bane hote hain. Snake shaped seedhe jaisa dikhane vaala yah ek lamba molecule hai. iske aakaar ko dohare helicks ke roop mein jaana jaata hai. Total teen billian rungs do outer strands ko jodate hain - iska seedha samarthan karata hai.two chemicals (pair) ke lie do base pair hote hain, jinase ve bane hote hain. vaigyaanik pratyek chemical ko isake praarambhik: A (adenine), C (cytosine), G (Guanine) aur T (Thymine) dvaara sandarbhit karate hain. A ke sath hmesha T air C ke sath hmesha G juda hota hai.

DNA ki bhoomika varnamaala ki bhoomika ke samaan hai. isamen soochanaon ko le jaane ki capability hoti hai, lekin keval agar aksharon ko aise tareekon se jod diya jae jo saarthak shabd banaate hain. ek saath string shabd nirdesh banaata hai, jaisa ki ek nuskha mein hai. to jeen koshika ke lie nirdesh hain. nirdeshon ki tarah, gene ki ek "shuruaat" hoti hai, jab tak ki ve kuchh paribhaashit "end" tak nahin pahunch jaate tab tak aadhaar jode ke unake string ko ek specific kram mein chalana chaahie.
