Answer :

The impact of the function of genes encoding HAT at the molecular level is a widespread reduction in gene expression.

What is gene expression?

Gene expression is a mechanism of gene transcription and mRNA translation that affects the protein produced.

There are three very important factors for understanding gene expression:

  • Molecular signal. Many types of molecules interact with cells, via cell surface proteins or intracellular receptors that stimulate signal transduction, so that cells can adapt to environmental changes.
  • Molecular hierarchical level. The degree to which the central dogma of molecular biology is involved in gene expression.
  • Molecular mechanism

The capping process (coding the hat) has the following functions:

  • This tip protects the mRNA from degradation by hydrolytic enzymes.
  • Once the mRNA reaches the cytoplasm, the 5' end serves as a "stick here" signal for the ribosome.
