Order the following words for Transcription<br> 1 pre-mRNA<br> 2.Gene<br> 3 DNA<br> 4mRNA
Paraphin [41]

Answer:

2. Gene

3. DNA

1. Pre-mRNA

4. mRNA

Explanation:

Transcription is the first step of gene expression in which a DNA molecule serves as template for the synthesis of mRNA. In the process of transcription, a Gene present on the DNA molecule is transcribed by RNA polymerase using complementary base pairing rule.

After the gene is transcribed, a pre-mRNA is formed. This mRNA is so called because it is immature. The pre-mRNA undergoes processing such as polyadenylation, splicing etc. to become a mRNA.

Hence, based on this, the order is:

Gene → DNA → pre-mRNA → mRNA
