Anatomy<br> Label each of the following structures or processes.

RSB [31]

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
