(a)
Interpretation:
The informational strand corresponds to the given template strand of DNA isto be determined.
Concept Introduction:
The first step of the synthesis of proteins using the information in DNA is transcription.
During transcription, the synthesis of messenger RNA (mRNA) from DNA takes place.
Only one DNA strand is needed for RNA synthesis, thus the double helix of DNA unwinds during transcription. The strand used for the RNA synthesis is called template strand. The other strand (the non-template strand) is called informational strandand does not involved in theRNA synthesis.The informational strand of DNA is complementary to the template strand.
(b)
Interpretation:
mRNA strand prepared by the given template strand is to be determined.
Concept Introduction:
The mRNA synthesized from transcription has a complementary sequence to the DNAtemplate from which it is prepared.
Since the informational strand of DNA is complementary to the template strand, themRNA is an exact copy of the informational strand, the only exception is that the base T present in the informational strand is replaced by U on the RNA strand.
(c)
Interpretation:
The polypeptide prepared from the mRNA strand is to be determined.
Concept Introduction:
The information needed to prepare a polypeptide is in the mRNA strand. Each sequence of three
