The answer is nucleic acid. Every nucleic acid is composed by a base, a sugar and a phosphate group. And they can form DNA or RNA by combining together.
Answer:
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
Explanation:
A hypotonic solution refers to a solution that has less solute and more water than another solution. Beaker 1 is hypotonic because it contains a lower percentage of solute (salt) than the solution in the bag.
An isotonic solution refers to a solution that has equal amounts of solute and water as another solution. Beaker 2 is isotonic because it has an equal percentage of solute compared to the bag.
A hypertonic solution refers to a solution that has more solute and less water than another solution. Beaker 3 is hypertonic because it contains a higher percentage of solute than the solution in the bag.
The answer is D.
Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
