Protein Synthesis B.7B

Protein synthesis occurs in two steps: the first step is (a)   and the second step is (b)   . Transcription is the process by which the enzyme (c)   makes messenger RNA (mRNA), using DNA as a template (DNA => mRNA). Transcription occurs in three steps: initiation, elongation, and

termination. Transcription occurs in the (d)   of eukaryotic cells and in the cytoplasm of prokaryotes.

The mRNA produced during transcription carries the genetic information that codes for a (e)   .

• transcription
• translation
• RNA polymerase
• protein
• nucleus
• replication
• cell membrane
• helicase

Match these nucleic acids with their function

• DNA

• Holds the code for how to make all the proteins in an organism

• rRNA

• Reads the codon from the nucleus and is the location for translation

• tRNA

• Contains the complimentary anticodon and brings a specific amino acid to the ribosome

• mRNA

• Genetic code stored in codons, copied from a template of one gene in the DNA
