Which structure is found in a protein but not in a nucleic acid?

The phosphorus elements constitute the backbone of the deoxyribonucleic acid molecules while they are absent within the arrangement of proteins. The element carbon constitutes the carboxyl group of amino acids and the sugar molecules of deoxyribonucleic acid.

What is the difference between the structure of proteins and amino acids?

Amino acids are called peptides, and they’re small subunits made from carbon, hydrogen, oxygen and other compounds. Proteins are also called polypeptides, and they’re chains of amino acids linked together — chains that can contain thousands upon thousands of amino acids.

How are nucleic acids and proteins the same?

Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

How are protein structures different?

The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure.

What are the different protein structures?

The different levels of protein structure are known as primary, secondary, tertiary, and quaternary structure. Primary Structure of Proteins. The primary structure is the sequence of amino acids that make up a polypeptide chain.

How do amino acids structurally differ from each other to be unique?

Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The largest group of amino acids have nonpolar side chains. Several other amino acids have side chains with positive or negative charges, while others have polar but uncharged side chains.

How are proteins and nucleic acids similar and different?

As molecules, proteins and nucleic acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they’re both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways.

How does protein and nucleic acid work together?

Deoxyribonucleic acid (DNA) stores the genetic information and directs the protein synthesis by the cells. The sequence of nucleotides in the DNA determines the sequence of amino acids in the protein. Ribonucleic acid (RNA) is involved in the synthesis of proteins.

Which part of the amino acid makes it different from other amino acids?

side groups
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called “R” groups, interact with the environment.
