Melanin provides pigmentation to the skin and it also provides UV ray protection (which is its role in the epidermis).
Answer:assuming it is LiAlSi2O6, you have lithium, aluminum, silicon, and oxygen. It’s difficult to tell with all of the letters capitalized. Only the first letter of the atom should be capitalized. A capital I is iodine.
Explanation:
Cellulose makes the cell walls of all plant cells.
Option B
<h3><u>Explanation:</u></h3>
Enzymes are biomolecules that act as biocatalysts and to enhance the rate of a chemical reaction. Lipids and proteins make up the cell membrane bilayer. Cholesterol is a lipid molecule that comes under the category of very low density lipoprotein. Its not associated with storing the genetic information. The DNA stores the genetic information.
Glucose is the chief respiratory substrate of a cell. Its not associated with the increase in rate of a reaction. But cellulose is the molecule that is a polymer of glucose that is associated with the formation of cell walls in plants.
Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
