Question

Anatomy Label each of the following structures or processes.

Answer 1

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

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

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.
