The Embryonic stem cells are capable of limited differentiation.
Answer:
Structure of DNA provides basic information about its packing, replication and copying of the stored genetic information. It tells how the parent DNA strands are copied during the process of cell division.
Explanation:
The double-helical structure of DNA is the basis for its ability to store the genetic information, to replicate itself and to transmit the genetic information. DNA is a polymer of four nucleotides. It stores the genetic information in the sequence of these four nucleotides. The complementary base pairing between the DNA bases tells how DNA template strands are copied during the process of replication.
The newly formed DNA strands have complementary nucleotide sequence to the template DNA strands. Similarly, during the transmission of genetic information, the nucleotide sequence of the DNA is copied into the nucleotide sequence of the mRNA. Therefore, knowledge about the structure of DNA is required to understand its functions.

Answer:
ΔG'° for the coupled reaction = -16.7 kJ/mol
<em>Note: The question is missing some parts. The complete question is as follows:</em>
<em>The first reaction in glycolysis is the phosphorylation of glucose:
</em>
<em>
Pi+glucose⟶glucose−6−phosphate+H2O
</em>
<em>This is a thermodynamically unfavorable process, with ΔG∘′= +13.8kJ/mol. In a liver cell at 37 ∘C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each.</em>
<em>This very low concentration of the desired product would be unfavorable for glycolysis. In fact the reaction is coupled to ATP hydrolysis to give the overall reaction: ATP + glucose → glucose-6-phosphate + ADP + H+</em>
<em>What is the ΔG'° for the coupled reaction?</em>
Explanation:
The coupling of ATP hydrolysis which is a thermodynamically favourable reaction to the phosphorylation of glucose makes it favourable. Since the two reactions constitute a sequential reaction, their standard free energy changes are additive.
For ATP hydrolysis: ATP + H₂O ---> ADP + Pi ; ΔG'° = -30.5KJ/mol
For phosphorylation of glucose: Pi + glucose⟶glucose−6−phosphate + H2O ; ΔG'° = +13.8 kJ/Mol
For the overall reaction: ATP + glucose → glucose-6-phosphate + ADP + H⁺ ; ΔG'° = 13.8 + (-30.5) kJ/mol = -16.7 kJ/mol
Therefore, ΔG'° for the coupled reaction = -16.7 kJ/mol
