Why hydrogen bonds are so important for living organisms.
Introduction:
Compounds like water, salt, etc., are formed when two substances are combined together. The force that holds the substances together is called a chemical bond.

Explanation of Solution
Hydrogen is very important for living organisms as it is required for the formation of water molecule. Water is a molecule formed by covalent bonds that link two hydrogen atoms with an oxygen atom. Hydrogen bonding partially determines the structure of proteins. A protein is composed of small carbon compounds called amino acids. Carbon can form four covalent bonds, one of which is with hydrogen. Hydrogen bonds are responsible for holding the strands of DNA together. In
Hydrogen bonding accounts for the unique solvent capabilities of water. Hydrogen bonds hold together complementary DNA strands, and they are responsible for determining protein structures.

Thank you!arrow_forwardplease draw in and fill out the empty slots from image below. thank you!arrow_forwardThere is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?arrow_forward

Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forward
