alleryDNA ର ଡବଲ-ହେଲିକ୍ସ (double-helix) ସଂରଚନା କାହା ଦ୍ୱାରା ଆବିଷ୍କୃତ ହୋଇଥିଲା?
A1866 ରେ Mendel ଏବଂ Darwin (ପ୍ରାରମ୍ଭିକ ଜେନେଟିକ୍ସ)
B1665 ରେ Hooke ଏବଂ Pasteur (ମାଇକ୍ରୋବାୟୋଲୋଜି ଯୁଗ)
C1953 ରେ Watson, Crick (ଏବଂ Franklin)
D1977 ରେ Sanger ଏବଂ Boyer (DNA ସିକ୍ୱେନ୍ସିଂ)
Answer & Solution
Correct answer: C. 1953 ରେ Watson, Crick (ଏବଂ Franklin)
Watson ଏବଂ Crick 1953 ରେ Rosalind Franklin ଙ୍କ X-ray diffraction ପ୍ରତିଛବି ଉପରେ ଆଧାର କରି DNA double helix ର ପ୍ରସ୍ତାବ ଦେଇଥିଲେ (ଯାହାଙ୍କ ଅବଦାନକୁ ଐତିହାସିକ ଭାବରେ କମ୍ ଶ୍ରେୟ ଦିଆଯାଇଥିଲା)।
Hooke କୋଷ ଆବିଷ୍କାର କରିଥିଲେ (1665); Mendel ଜେନେଟିକ୍ସର ମୂଳଦୁଆ ପକାଇଥିଲେ (1866)।
