Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Proteins, starch, and DNA are similar in that they are all
A
organic compounds
B
parts of genes
C
made of amino acids
D
made of simple sugars
Explanation: 

Detailed explanation-1: -Indeed, proteins, starch and DNA are all considered to be organic compounds. Organic compounds are molecules that contain carbon in them, oftentimes containing hydrogen and oxygen. All of the compounds listed above contain carbon and are therefore organic.

Detailed explanation-2: -DNA and proteins are both polymers. They are made of many little pieces joined into long chains. DNA is made of pieces called nucleotides. Proteins are made of pieces called amino acids.

Detailed explanation-3: -Answer and Explanation: DNA, RNA, and starch are all biopolymers. Furthermore, their monomers contain a sugar unit. DNA and RNA have repeating units that contain a 5 carbon sugar, as well as a phosphate group and a nitrogenous base.

Detailed explanation-4: -Organic Compounds are found in: carbohydrates, lipids, protein, and nucleic acids.

Detailed explanation-5: -The nucleotides of DNA consist of a deoxyribose sugar molecule to which is attached a phosphate group and one of four nitrogenous bases: two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
