Question
Chapter 30, Problem 2P
Interpretation Introduction
Interpretation:
The reason for the DNA synthesis is more carefully monitored for errors than RNA synthesis should be determined.
Concept introduction:
DNA synthesis can be defined as the process by which the deoxynucleic acids such as adenine, thymine, cytosine, and guanine are associated together to form DNA.
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The

True or False. Explain.
A) At no time during protein synthesis does an amino acid make direct
contact with the mRNA being translated.
B) Because the two strands of DNA are complementary, the mRNA of a gene can be synthesized using either strand as a template.
the correct reading frame.
next thing to do is to write out the mRNA sequence using this sense strand reading frame.
The last thing to do is to translate the sequence.
The reading frame DNA sequence is:
The mRNA sequence is:
The polypeptide sequence is:

In eukaryotic gene, the coding sequences are known as introns while the intervening sequences are the exons. The central dogma refers to the fact that proteins are products of information encoded in RNA using a DNA intermediate.
