How is a strand of DNA like a sentence?
2 answers:
Answer:
DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA "sentences" within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.
Explanation:
A strand of DNA is much like an extremely long sentence that uses only four letters. DNA actually has two strands, much like a zipper and the nucleotides are like the teeth of that zipper. This two-strand system is the key to how DNA is able to make copies of itself.

<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which do not get involved in the chemical equation. It is also defined as the ions which are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of ammonium perchlorate and water is given as:
Ionic form of the above equation follows:
Ammonium hydroxide will not dissociate into its ions because it is a weak base.
As, chlorate ions are present on both the sides of the reaction, thus, it will not be present in the net ionic equation.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is given above.
