The two sources of information used to direct the expression of genes during various stages of development are Transcription and Translation.
<h3><u>Explanation:</u></h3>
Both of them combined is called gene expression.Transcription is the process of sharing information stored in a DNA to RNA.
The process of translation is carried out in cytoplasm. Here, the mRNA, in which stands for messenger, send messages to a more complex and specialized molecule called the ribosome. The sequence present on the mRNA base is read by the ribosome.
Transcription takes place in nucleus and translation takes place in Cytoplasam. The products of transcription are mRNA, tRNA, rRNA. The products of translation are Proteins.
