Question

All organisms' cells contain DNA. Every organism's DNA is made of nucleotides. Although, the four species on this phylogenic tree are different, which components of their DNA are the same? Species = Human , Chimp, Gorilla, Orangutan

A = sugar deoxyribose and the base thymine.

B= sugar deoxyribose and the base uracil.

C= sugar ribose and the base thymine

D= sugar ribose and the base uracil.

Answer 1

A = sugar deoxyribose and the base thymine.

Step-by-step explanation:

DNA is the storage molecule of the genetic information in almost all cells of living organisms. DNA is one of the two types of nucleic acids, a biological polymer made up of monomeric units called NUCLEOTIDES.

Nucleotides of a DNA are composed of three major substances that make up its structure. The three components are; a pentose sugar (deoxyribose), phosphate group and nitrogenous bases, which can be Adenine, Thymine, Guanine and Cytosine.

Based on this question, although the following four species are different: Human , Chimp, Gorilla, Orangutan, but their DNA contains the following same components; sugar deoxyribose and the base thymine. This is because all DNA has deoxyribose instead of ribose and thymine instead of uracil.
