Chapter 16.3, Problem 2SB
Summary Introduction
To review:
The effect on the translation of the mRNA when the poly-A tail on the mRNA is eliminated.
Introduction:
The central dogma states that information flows from the DNA to the synthesis of the protein. In this, the DNA is converted into the RNA through the process of transcription, which undergoes the process of posttranscriptional modification and gives rise to the mRNA that further moves into the process of translation and produces the protein.
