C. The hydrophobic heads of the phospholipids orient themselves toward the extracellular and intracellular environments, and the hydrophilic tails of the phospholipids orient themselves toward each other, forming a phospholipid bilayer. D. The hydrophilic heads of the phospholipids orient themselves toward the extracellular and intracellular environments, and the hydrophobic tails of the phospholipids orient themselves toward each other, forming a phospholipid bilayer. E. The nonpolar heads of the phospholipids orient themselves toward the aqueous extracellular and intracellular environments, and the polar tails orient themselves toward each other, away from water, forming a phospholipid bilayer.

00:01 Hello everyone here our question is related to the polynucleotide strand of the dna okay so whenever we talk about the poly nucleotide strand of the dna if we talk about a dna molecule we know that a dna molecule basically have two ends all right one will be the five prime and and the other one will be the three prime end when we talk about this five prime end we know that this five prime end is is basically attached to a phosphate group.

00:35 And when we talk about this 3 prime end, it is generally attached with a hydroxyl group.

00:45 All right? so this is what we know.

00:48 Now we are provided with five different statements.

00:52 The first statement is saying that the 5 prime end of the dna is attached to hydroxyl group.

00:59 So it is a wrong statement.

01:00 Because 5 prime end is attached to phosphate group.

01:04 If we look at the statement b, it is saying that the 5 prime end is attached to phosphate group.

01:11 So, this will be the correct statement here.

01:14 Statement c is saying that the 3 prime end is attached to hydroxyl group.

01:19 Again, it is the correct statement.

01:22 Option d is saying that the 3 prime end is attached to phosphate group, so it is the incorrect one.

01:28 And the last option is saying that both ends are identical.

01:34 We have seen that both ends are not identical...
