Question

Protein synthesis actually begins in the nucleus when ___15___ transcribes ___16___. A single gene on the DNA molecule is copied. The process of copying this gene is called ___17___. This copy is known as ___18___ and contains the protein building instructions. This copy is sent out into the cytoplasm to the part of the cell known as the ___19___. The ___20___ of the ribosome will join together to form a functional ribosome when they attach to the mRNA. As the mRNA moves through the ribosome, the message is read by ___21___. Transfer RNA brings the correct ___22___ back to the ribosome. The amino acids are placed in the correct order and are hitched together by ___23___.

Answer 1

15. DNA

16. RNA  

17. Transcription

18. mRNA

19. ribosome

20. subunits

21. tRNA

22. anticodon

23. peptide bonds.

The procedure of protein synthesis is as follows:

1. Within the cell nucleus, transcription process starts and mRNA is synthesized from DNA

2. mRNA after transcription move out of the nucleus and enter the cytoplasm.  

3. mRNA then attaches to the start condon of the ribosome.  

4. Amino acid is then carried by the tRNA to the ribosome.

5. The protein in its complete states is released for use.  

6. Protein synthesis is then stopped by a stop codon  

7. More amino acids are added to the growing protein as the ribosome moves along the mRNA
