Anti-parallel strands of a DNA molecule mean thata)One strand turns an...
Explanation:
Introduction:
DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in all living organisms. It consists of two long strands that are twisted around each other to form a double helix structure. The two strands are held together by hydrogen bonds between complementary nucleotide bases.
Anti-parallel Strands:
In a DNA molecule, the two strands are said to be anti-parallel to each other. This means that the strands run in opposite directions, with one strand running from the 5' end to the 3' end and the other strand running from the 3' end to the 5' end.
Explanation of the options:
a) One strand turns anticlockwise:
This option is incorrect because the direction of twisting or turning of the DNA molecule is not related to the concept of anti-parallel strands. The direction of twisting is determined by the chirality or handedness of the DNA molecule.
b) Phosphate groups at the start of two DNA strands (poles) are in opposite positions:
This option is correct. The phosphate groups are located at the 5' end of each DNA strand. In an anti-parallel DNA molecule, the phosphate group of one strand is positioned at the opposite end, or pole, compared to the phosphate group of the other strand.
c) Phosphate groups of two DNA strands at their ends share the same position:
This option is incorrect. In an anti-parallel DNA molecule, the phosphate groups of the two strands are not positioned at the same end. They are located at opposite ends, with one strand having the phosphate group at the 5' end and the other strand having the phosphate group at the 3' end.
d) One strand turns clockwise:
This option is incorrect because the direction of twisting or turning of the DNA molecule is not related to the concept of anti-parallel strands. The direction of twisting is determined by the chirality or handedness of the DNA molecule.
Conclusion:
In conclusion, the correct answer is option 'B' - the phosphate groups at the start of two DNA strands (poles) are in opposite positions. This is one of the key characteristics of anti-parallel strands in a DNA molecule.
