Composition is what it's made of vs texture being what the substance feels like.
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
37. Observation and scientific theory are both related. Because it needs hypothesis and experiment to be able to have an actual data to show.
For example:
If you want to know how a monggo seeds grow on a wet cotton. Then you should be preparing the needed things and perform the experiment. You need to observe to be able to get the scientific theory of how this experiment works. That’s how observation and scientific theory is related. They will always be together in science.
DNA is made of a double helix of two complementary strands. When replicating, these strands seperate. Each strand of the original DNA then acts as a template for the production of it's counterpart, which is referred to as semiconservative replication.
