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
High concentrations of salt can inhibit the growth of bacteria by causing the bacteria to shrink because water leaves the bacterial cell.
<h3>What is a Hypertonic solution?</h3>
This is defined as a type of solution which has a large amount of particles which are dissolved thereby making it have a high concentration.
High concentrations of salt applied to the outside of the meat means it is hypertonic and therefore causes the bacteria to shrink because water molecule leaves the cells thereby destroying their structure preventing metabolic reactions from occurring which leads to their death.
