Limitations of Northern Blotting or Which of the following analysis cant be done using Northern blotting
A. Approximate size of an mRNA
B. Relative abundance of an mRNA in various cells or tissues
C. Relative stability of an mRNA in a given cell or tissue
D. Identify of all mRNAs in a given cell or tissue
Correct Answer: (D) Identity of All mRNAs in a Given Cell or Tissue
Northern blotting is a widely used molecular biology technique for detecting specific mRNA molecules within a sample. It provides valuable insights into gene expression patterns, but it has limitations regarding the global identification of all mRNAs present in a cell or tissue.
What Northern Blotting Can Do?
-
Determine the Approximate Size of an mRNA (Option A)
- Since Northern blotting separates mRNA based on size via gel electrophoresis, it allows researchers to estimate the molecular weight of specific mRNAs by comparing them to known markers.
-
Measure Relative Abundance of mRNA (Option B)
- The intensity of hybridization signals correlates with the amount of mRNA in a sample.
- This helps compare gene expression levels across different tissues or experimental conditions.
-
Assess Relative Stability of an mRNA (Option C)
- By performing Northern blot analysis at different time points after transcription inhibition, scientists can evaluate how long a specific mRNA persists, providing insight into its stability and degradation rate.
Why Northern Blotting Cannot Identify All mRNAs?
- Northern blotting is a targeted technique that requires a specific probe complementary to the mRNA of interest.
- It cannot comprehensively identify all mRNAs present in a cell or tissue, as it only detects mRNAs that hybridize with the labeled probe.
- Identifying the entire transcriptome requires techniques like RNA sequencing (RNA-seq) or microarray analysis, which can analyze thousands of mRNAs simultaneously.
Conclusion
While Northern blotting is valuable for studying individual mRNA expression, it cannot identify all mRNAs in a given cell or tissue, making option D the correct answer.

Aafreen
August 20, 2025ANS-D– Identity of All mRNAs in a Given Cell or Tissue
It cannot identify all mRNAs present in a cell or tissue, it only detects mRNAs that hybridize with the labeled probe.
Heena
August 20, 2025Northern blotting can’t identify all mRNAs in given cell as it identifies a single specific rna

Komal Soni
August 20, 2025We can be used northern blotting for measuring size, quantification or find out stability of RNA but identify all mRNAs in a given cell or tissue is possible with the chromosome painting (FISH)
Shivani
August 20, 2025Option D. Is correct
Northern blotting can not detect all mRNAs in a given cell because it detect only mrna that hybridize with labeled probe.
Mansukh Kapoor
August 20, 2025The correct answer is option 4th
Because by the northern blotting we cannot identify the all mRNAs of the cell
Khushi Mehra
August 20, 2025Option 4 is correct
All the mRNAs of a given cell or tissue cannot be identified by Northern blotting technique.
Northern blotting technique is used to detect a specific mRNA that bind with the labelled specific DNA probe.

August 26, 2025Northern blotting s mrna ki size pta kr skte
Ladder (known sequence) s compare kr molecular weight pta kr skte h
Abundance bhi pta kr skte h fluroscent intensity s gene expression level pta kr skte h jitni jyada intensity utna m rna hota h
Band width s abundance pta nhi kr skte band width s m rna ki size kaa pta chlta h
Transcription ko inhibit kr k alag alag time p Northern blotting krke m rna ki stability check kr skte h saath hi degradation rate bhi pta kr skte h
Northern blotting s specific m rna ki detect krte h kyoki specific probe specific m rna sequence s bind krta h jo uska complimentary ho
