The given question is which of the following statement is untrue regarding tna? the given options are phosphate groups link the third position of one sugar to the fifth position of the next sugar.
00:10
Next option forms a right -handed double helix.
00:13
Third option in a thymine adenosine base pairs, two hydrogen bonds are formed.
00:17
Next option, in a cytosine and base pairs, three hydrogen bonds are formed and last option.
00:22
The basis lies on the outside of the helix while the backbone lies on the inside of the helix.
00:27
So now first, let's talk about option.
00:33
In a watson and cricks model, the two strands of dna twists around each other to form a right -handed double heli structure.
00:47
All halis says have a handedness which is property that describes how their growths are oriented in a space.
00:59
So the given statement is true.
01:04
Now let's talk about the option c and d.
01:11
Adinin pairs with thymine with two hydrants.
01:15
Hydrogen bond and gonin pairs with cytosine with three hydrogen bonds...
