1. A Mutation Occurs In A Strand Of Replicated DNA. The Correct Codon In This Strand Should Be CCU, But Instead, The Mutation Has Resulted In CCA. Will This Mutation Result In A Change In The Resulting Protein? Use The Chart Below To Help

1.1 Understanding the Basics of DNA and Protein Synthesis

DNA (Deoxyribonucleic acid) is a molecule that contains the genetic instructions used in the development and function of all living organisms. It is made up of two strands of nucleotides that are twisted together in a double helix structure. Each nucleotide is composed of a sugar molecule called deoxyribose, a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

During protein synthesis, the sequence of nucleotides in a DNA molecule is transcribed into a complementary RNA (Ribonucleic acid) molecule. This RNA molecule is then translated into a sequence of amino acids that make up a protein. The sequence of nucleotides in the DNA molecule determines the sequence of amino acids in the protein.

1.2 The Genetic Code and Codons

The genetic code is a set of rules that determines how the sequence of nucleotides in a DNA molecule is translated into a sequence of amino acids in a protein. The genetic code is made up of codons, which are sequences of three nucleotides that specify a particular amino acid or stop signal.

The chart below shows the genetic code for the standard genetic code:

1.3 Understanding the Genetic Code and Codons

The genetic code is a set of rules that determines how the sequence of nucleotides in a DNA molecule is translated into a sequence of amino acids in a protein. The genetic code is made up of codons, which are sequences of three nucleotides that specify a particular amino acid or stop signal.

1.4 Q&A: Understanding the Genetic Code and Codons

Q: What is the genetic code?

A: The genetic code is a set of rules that determines how the sequence of nucleotides in a DNA molecule is translated into a sequence of amino acids in a protein.

Q: What are codons?

A: Codons are sequences of three nucleotides that specify a particular amino acid or stop signal.

Q: How does the genetic code work?

A: The genetic code works by translating the sequence of nucleotides in a DNA molecule into a sequence of amino acids in a protein. Each codon specifies a particular amino acid or stop signal.

1.5 Understanding the Mutation

The correct codon in this strand should be CCU, but instead, the mutation has resulted in CCA. This means that the mutation has changed the third nucleotide in the codon from U to A.

1.6 Q&A: Understanding the Mutation

Q: What is the correct codon in this strand?

A: The correct codon in this strand is CCU.

Q: What is the mutated codon?

A: The mutated codon is CCA.

Q: What has changed in the mutated codon?

A: The third nucleotide in the codon has changed from U to A.

1.7 Will the Mutation Result in a Change in the Resulting Protein?

To determine whether the mutation will result in a change in the resulting protein, we need to look at the genetic code chart.

As we can see from the chart, the correct codon CCU specifies the amino acid Leucine (L), while the mutated codon CCA specifies the amino acid Proline (P). This means that the mutation has resulted in a change in the resulting protein.

1.8 Q&A: Will the Mutation Result in a Change in the Resulting Protein?

Q: Will the mutation result in a change in the resulting protein?

A: Yes, the mutation will result in a change in the resulting protein.

Q: What is the change in the resulting protein?

A: The change in the resulting protein is that the amino acid Leucine (L) is replaced by the amino acid Proline (P).

1.9 Conclusion

In conclusion, the mutation in the strand of replicated DNA has resulted in a change in the resulting protein. The correct codon CCU specifies the amino acid Leucine (L), while the mutated codon CCA specifies the amino acid Proline (P). This means that the mutation has resulted in a change in the resulting protein.
