Translation: DNA To mRNA To Protein! Biology Trivia Quiz

1. Codons are read in series of ...?

3

4

5

2

Codons are read in series of 3 nucleotides. Each codon corresponds to a specific amino acid, which is the building block of proteins. The sequence of codons determines the sequence of amino acids in a protein. Therefore, the correct answer is 3.

Explanation

Codons are read in series of 3 nucleotides. Each codon corresponds to a specific amino acid, which is the building block of proteins. The sequence of codons determines the sequence of amino acids in a protein. Therefore, the correct answer is 3.

2. If the mRNA strand was AUUGCGUUU, what would the series of tRNA anti-codons be?

The tRNA anti-codons are the codons located on the transfer RNA that bring over the correct amino-acid.

Explanation

The tRNA anti-codons are the codons located on the transfer RNA that bring over the correct amino-acid.

3. Where does the process of translation occur?

Nucleus

Golgi Appartus

Ribosome

Lysosome

Ribosomes read the mRNA and code for amino acids.

Explanation

Ribosomes read the mRNA and code for amino acids.

4. What is the matching amino acid sequence for the following mRNA strand? AUUGGUAUU

Iso-Leu-Gly

Iso-Gly-Iso

Iso-Gly-Gly

Syr-Tyr-Stop

The mRNA sequence AUUGGUAUU codes for the amino acid sequence Iso-Gly-Iso. This is determined by using the genetic code chart, which matches each three-letter codon in mRNA to a specific amino acid. In this case, the codon AUU codes for the amino acid isoleucine (Iso), the codon GGU codes for the amino acid glycine (Gly), and the codon UAU codes for the amino acid isoleucine (Iso) again. Therefore, the correct matching amino acid sequence for the given mRNA strand is Iso-Gly-Iso.

Explanation

The mRNA sequence AUUGGUAUU codes for the amino acid sequence Iso-Gly-Iso. This is determined by using the genetic code chart, which matches each three-letter codon in mRNA to a specific amino acid. In this case, the codon AUU codes for the amino acid isoleucine (Iso), the codon GGU codes for the amino acid glycine (Gly), and the codon UAU codes for the amino acid isoleucine (Iso) again. Therefore, the correct matching amino acid sequence for the given mRNA strand is Iso-Gly-Iso.

5. If the mRNA strand reads AAUCCUGGG, what would be the correct amino acid sequence?

Asp-Val-Ser

Asp-Val-Val

Asp-Pro-Gly

The mRNA strand reads AAUCCUGGG, which corresponds to the codons AAU, CCU, and GGG. The codon AAU codes for the amino acid Asp (aspartic acid), CCU codes for Pro (proline), and GGG codes for Gly (glycine). Therefore, the correct amino acid sequence is Asp-Pro-Gly.

Explanation

The mRNA strand reads AAUCCUGGG, which corresponds to the codons AAU, CCU, and GGG. The codon AAU codes for the amino acid Asp (aspartic acid), CCU codes for Pro (proline), and GGG codes for Gly (glycine). Therefore, the correct amino acid sequence is Asp-Pro-Gly.
