A phosphate group is a functional group that typically has a negative charge at the pH of the cell.
- Phosphate groups contain a negative charge at physiological cell pH.
- DNA nucleotides are composed of a phosphate group, thereby exhibiting a negative charge.
- The phosphate group is also fundamental in Adenosine triphosphate or ATP (the energy coin of the cell).
In conclusion, a phosphate group is a functional group that typically has a negative charge at the pH of the cell.

Answer:
The correct answer is -
gly-met-arg-phe-val-pro
Explanation:
The production of the amino acid chain or sequence from the desired DNA sequence is called the protein synthesis or central dogma that involves two processes, transcription and translation. Transcription is the process of transcribing the information encoded in the DNA sequence into a complementary mRNA sequence. The translation is the second process that involves the translation from mRNA to a specific amino acid.
mRNA sequence is complementary to the DNA
so, DNA - CCC-TAC-CGC-AA-CG-CC
mRNA - GGG-AUG-CGC-UUU-GUC-GG
and amino acid from the chart : gly-met-arg-phe-val-pro
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
