Answer:
Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.
Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.
Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding
Explanation:
The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.
For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.
The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.
Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.
This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.
Answer: Deoxyribose
Explanation:
The Deoxyribonucleic acid is the genetic material found in all the living organism.
The genetic information is transferred in the form of codes from one generation to another in the from of DNA.
The DNA consists of sugar, nitrogenous bases and phosphate group. The sugar part is ribose sugar which is a type of pentose sugar.
Hence, the correct answer is option C
Answer:
Prey is the things that are hunted, while predator are the hunters
Explanation:
Foxes hunt mice, making the mice the prey and the fox the predator
Lions hunt gazelle, making the gazelle the prey and the lion the predator
Summer is about to begin the hemisphere
Your welcome
Answer:
Cells
Explanation:
Cells are the smallest living unit, but atoms are the smallest unit of the above choices... Cells are made of atoms... But you asked about the Smallest unit of life so I don't know if you are asking about the smallest unit ever or the smallest unit in the living things
