Which of these structures can be found in BOTH plant and animal cells?

Explanation:

1. To get a protein from gene, the process of transcription first occurs in which the gene ( DNA ) is transcribed into mRNA with the help of RNA polymerase and many other enzymes. It occurs in nucleus.

2. After transcription, this mRNA translate into protein through the process known as translation, this process occurs by the various enzymes and it also  require ribosomes and tRNA. It occurs in cytoplasm.
