To examine: Whether the statement “the consequences of errors in transcription are less severe than those of errors in
Introduction:
DNA is known as the blueprint of life as it controls gene expression. It directs messenger RNA (mRNA) synthesis in the cell through transcription. During formation of mRNA, each letter in the gene sequence is copied which codes for a particular protein. The genetic information in mRNA is translated for the synthesis of polypeptide chains. This is known as gene expression.
Answer to Problem 1P
Correct answer: The statement is true.
Explanation of Solution
Every time a cell divides and its DNA replicates, it has to copy and transmit the exact same sequence of billions of nucleotides to its daughter cells. Despite the high fidelity of the process, errors occur. DNA consists of basic genetic information that code for protein synthesis. If any error occurs in coding DNA
Hence, the statement is true.
