The component of transcribed RNA in eukaryotes that is present in the initial transcript but is removed before translation occurs is the intron.

Here are the steps explaining this process:

1. Transcription: In the nucleus of a eukaryotic cell, an enzyme called RNA polymerase binds to a region of DNA. It unwinds and opens the DNA helix, reads the genetic code, and synthesizes a pre-messenger RNA (pre-mRNA) molecule, which is a copy of the gene.

2. RNA Splicing: The pre-mRNA molecule includes regions called exons, which code for proteins, and regions called introns, which do not. The introns are removed in a process called RNA splicing. This process is facilitated by a complex called the spliceosome, which cuts out the introns and joins the exons together to form a mature mRNA molecule.

3. Translation: The mature mRNA molecule leaves the nucleus and goes to the ribosome, where it is translated into a protein. The introns, having been removed during RNA splicing, are not present in the mRNA molecule at the time of translation.

So, the introns are the components of transcribed RNA in eukaryotes that are present in the initial transcript but are removed before translation occurs.
