Tomato 5 D. Sweet potato E. Rice

Explanation / Answer

16. Answer is option A and B.

Transcription and translation are integral parts of decoding DNA and synthesizing protein. Replication s part of cell division and recombination is part of reproduction but not gene expression.

17. Answer is option E. amino acid

Amino acids are coded by the codons. A total of 64 codons are possible by combination of nucleotides.

18. Answer is option C. DNA>RNA>Protein

The DNA is trnacribed into RNA. RNA is translated into protein

19.Answer is option C. Monarch butterfly
