Question
The primary structure of a protein is directly encoded by the DNA. The DNA code is considered unambiguous because a given codon only specifies one amino acid. More than one codon can specify the same amino acid. Transcription: Is the process of making an RNA copy of the DNA code It accomplished by complimentary base pairing between DNA and RNA nucleotides Takes place in the nucleus in eukaryotes Requires ribosomes a, b, and c are correct Translation: Is the process of making an RNA copy of the DNA code Is accomplished by complimentary base pairing between DNA and RNA nucleotides Takes place in the nucleus in eukaryotes Requires ribosomes a, b, and c are correct Which of the following statements about the Genetic Code is NOT true? The Genetic Code is virtually universal The Genetic code is a triplet code Multiple codons may encode the same amino acid A given codon will never code for more than one ammo acid None (All of the above statements are true).Explanation / Answer
26. T
The primary structure is the protein sequence itself, which is encoded in the DNA.
27. T
If a given codon will specify more than one amino acid, significance changes in the protein sequence can occur, which may affect the cell’s viability.
28. T
There are 64 codons and 20 amino acids, which only means that more than one codon code for the same amino acid. Except Methionine and Tryptophan, all other amino acids have more than one codon.
29. (e)
The RNA polymerase binds to the DNA and incorporates ribo-nucleotides by reading the DNA, complementary to it. This takes place in the nucleus.
30. (d)
Ribosome is the site for protein synthesis.
