Homework Answers
Answer:
Each codon of mRNA represent an amino acid. If the sequence of the nucleotides in the mRNA changes the following amino acids may or may not change.
1).
If the UCA is changed to UCC, there is no effect. Because, both the codons represent the same amino acid, serine. So, there is no effect of mutation. This mutation is called silent mutation.
2).
If the UAC is changed to UAG, there is an effect on resulted peptide. Because, the UAC codons represent the amino acid, Tyrosine and the UAG codon represents the STOP (termination of peptide) . So, there is an effect of mutation. This mutation is called nonsense mutation.

TranslationOverview:The purpose of this activity is to help the students to understand how replication, transcription, and translation are connected. Students will use a sequence from a bacterial gene that confers resistance to antibiotics (carbapenems). They will be asked to apply the knowledge obtained in the class lecture to (1) find the promoter in the sequence, (2) determine the amino acid sequence of a fragment of the polypeptide, (3) "reverse translate" a fragment of the polypeptide, and (4) identify mutations in...

A mutation is a permanent change in the sequence of nucleotide bases in a cell's DNA. Most mutations happen during DNA replication, but their effects are not seen until transcription and translation. Even a small mutation that changes a single nucleotide can have a major impact on the resulting proteins that are made in the cell. с The table following the amino acid chart lists a segment of a normal gene. Type in the corresponding mRNA strand and the amino...

Sickle-cell Anemia Study Sickle-cell anemia or Sickle-cell disease, is a hereditary disorder. characterized by aryabnormality in the oxygen-carrying hemoglobin molecule in erythrocytes. Sickle-cell conditions have an autosomal recessive pattern of inheritance from parents. The sickle cell defect is a mutation of a single nucleotide of the hemoglobin B gene, which results in glutamic acid being substituted by a different amino acid at position 6. Hemoglobin with this mutation is referred to as Hbs, as opposed to the normal hemoglobin HbA....
