Concept explainers
Interpretation:
Nitrogenous base found in DNA and RNA needs to be explained.
Concept introduction:
The nitrogenous base contains nitrogen and has the chemical properties of a base.
RNA- ribonucleic acid, RNA is a
DNA- deoxyribonucleic acid, it is a genetic material for a cell. Itis consists of a deoxyribose sugar, a phosphate, and nitrogenous bases.
Answer to Problem 33A
The nitrogenous bases in DNA are
Adenine (A)
Guanine (G)
Thymine (T)
Cytosine (C)
The nitrogenous bases in RNA are
Adenine (A)
Guanine (G)
Uracil (U)
Cytosine (C)
The uracil base is found in RNA but not in DNA.
The thymine base is found in DNA but not in RNA.
Explanation of Solution
The nitrogenous bases in DNA are of four types. These are adenine (A), guanine (G), thymine (T), and cytosine (C).
The nitrogenous bases in RNA are as adenine (A), guanine (G), uracil (U), and cytosine (C).
There is a difference based on only one nitrogenous base that is uracil present only in RNA, while the thymine is present in the DNA.
The three nitrogenous bases of RNA and DNA are the same adenine (A), guanine (G),cytosine (C).
But the difference in RNA and DNA with two nitrogenous base
Thymine for DNA
Uracil for RNA
