6. the is the the way that the four bases of dna - the a, c, g, and ts - are strung together in a way that the ribosome can read them and turn them into a protein.
7. a(n) is a sequence of three nucleotides which together form a unit of genetic code in an mrna molecule.
8. an organelle which synthesizes proteins by translating codons into chains of amino acids is a(n)
9. the second phase of protein synthesis which takes place in the cytoplasm on the ribosome and translates codons in the mrna into chains of amino acids (polypeptides)

Explanation:

1. A polymer of amino - acids is a polypeptide.
2. The three - nucleotide sequence in tRNA corresponding to mRNA codon is an anticodon.
3. The RNA that transfers amino acids to the ribosome is tRNA.
4. Amino acids are the building blocks of proteins.
5. The first codon (AUG) that codes for methionine is the start codon.
6. The way DNA bases are strung together for ribosome to read and make protein is the genetic code.
7. A three - nucleotide sequence in mRNA is a codon.
8. The organelle that synthesizes proteins by translating codons is the ribosome.
9. The second phase of protein synthesis in the cytoplasm on the ribosome is translation.
