In eukaryotes which of the following us removed from initially transcr...
Introduction:
Eukaryotic genes are transcribed into RNA, which is then processed in several ways before it can be transported to the cytoplasm for translation. One of the key events in RNA processing is the removal of certain sequences from the initially transcribed RNA. This ensures that the final mRNA molecule is both stable and capable of being translated by ribosomes.

The Answer:
The sequence that is most commonly removed from initially transcribed RNA in eukaryotes is the intron. Intron is a non-coding sequence of RNA that interrupts the coding sequence (exons) of a gene. The intron is removed by a process called splicing, which involves the excision of the intron sequence and the joining of the exons.

Other RNA Processing Events:
In addition to splicing, other processing events occur in eukaryotic RNA before it can be transported to the cytoplasm for translation. These include:

- Addition of a 5' cap: A modified guanine nucleotide is added to the 5' end of the mRNA molecule. This cap protects the mRNA from degradation and helps to initiate translation.

- Addition of a 3' poly(A) tail: A string of adenine nucleotides is added to the 3' end of the mRNA molecule. This tail also helps to protect the mRNA from degradation and is involved in the export of the mRNA from the nucleus.

- Editing: In some cases, the RNA molecule is edited after transcription by the addition, deletion, or modification of nucleotides. This can alter the coding sequence and result in the production of different protein isoforms.

Conclusion:
In summary, the most common sequence that is removed from initially transcribed RNA in eukaryotes is the intron. This is achieved by a process called splicing, which removes the intron sequence and joins the exons. Other processing events, such as the addition of a 5' cap and a 3' poly(A) tail, also occur before RNA can be transported to the cytoplasm for translation.

Introns are the non coding sequences in newly formed messanger RNA which must be removed for making mRNA functional for translation. This is done by splicing of mRNA after transcription. So, option a is correct.
