A geneticist isolates a gene for a specific trait understudy. She also isolates the corresponding mRNA. Upon comparison, mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA?
- a)Yes, mRNA is made from a DNA template and should be of same length as the gene sequence.
- b)Yes, mRNA should contain more bases than the DNA sequence because bases flanking the gene are also transcribed.
- c)No, the final mRNA contains only exons, the introns were removed.
- d)No, mRNA was partially degraded after it was transcribed.
Correct answer is option 'C'. Can you explain this answer?

Hn rna which is formed by help of rna polymerase 2 undergoes capping, tailing and splicing to convert into mrna.in splicing process the introns are removed and extrons are joined so they have less number bases than the piece of DNA which is actually getting transcribed so i think option c

The correct answer is option 'C': No, the final mRNA contains only exons, the introns were removed.
Explanation:
mRNA, or messenger RNA, is a molecule that carries the genetic information from DNA to the ribosomes, where it is translated into a protein. mRNA is transcribed from a DNA template, and during this process, certain segments of the DNA called introns are removed, while the remaining segments called exons are spliced together to form the final mRNA molecule.
Breaking down the options:
a) Yes, mRNA is made from a DNA template and should be of the same length as the gene sequence.
This option is not correct because mRNA is typically shorter than the corresponding DNA sequence. This is because introns, which are non-coding regions of DNA, are removed during mRNA processing.
b) Yes, mRNA should contain more bases than the DNA sequence because bases flanking the gene are also transcribed.
This option is not correct because the mRNA sequence is typically shorter than the DNA sequence it is transcribed from. The flanking bases are not transcribed into mRNA.
c) No, the final mRNA contains only exons, the introns were removed.
This option is correct. During mRNA processing, the introns are removed, and only the exons, which contain the coding regions of the gene, are included in the final mRNA sequence. This results in a shorter mRNA sequence compared to the original DNA sequence.
d) No, mRNA was partially degraded after it was transcribed.
This option is also incorrect because the length difference between the DNA sequence and mRNA is not due to degradation. The difference is a result of the removal of introns during mRNA processing.
In summary, the geneticist did not isolate the wrong DNA. The mRNA sequence is typically shorter than the corresponding DNA sequence because it only contains the coding regions (exons) of the gene, while the non-coding regions (introns) are removed during mRNA processing.
