Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
Scientists and biologists study the world using experimentation. This can be done through observation, or by performing scientific tests in a lab.
In population genetics, directional selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype
Answer:
The correct answer is - Polymers are macromolecules
Explanation:
Macromolecules are termed as macro and molecules mean huge atoms, for instance, proteins. It is made by the polymerization of monomers. Macromolecules are being made out of numerous atoms.
The usually utilized atoms in natural chemistry are lipids, carbohydrates, nucleic acid, and proteins, all are made of their respective monomers that are fatty acids, monosaccharides, nucleotides, and amino acids.
Thus, the correct answer is - Polymers are macromolecules
