Chapter 21, Problem 35A

Interpretation Introduction

Interpretation:

The name applied to the specific section of the DNA molecule containing the code for construction of a particular protein must be explained.

Concept Introduction:

DNA is the nucleic acid which has double helical structure. The two strands are connected through Watson-Crick base pairing with the help of hydrogen bonds.

DNA contains the genetic material which is carried from one generation to another from parents to offsprings.

Answer to Problem 35A

The specific section of the DNA molecule that contains the code for construction of a particular protein is known as Gene.

Explanation of Solution

DNA has very long length with millions of nucleotides. A part of the DNA undergoes transcription to form mRNA which ultimately generates a particular protein. This portion of the DNA is known as gene. Remaining portion which is not converted mRNA in the process of transcription is known as UTR (untranslated region) as this part doesn’t contain the code for protein formation.

Conclusion

The specific portion of the DNA molecule that contains the code for a particular protein formation is called Gene.
