In bacteria and eukaryotes, a mutation is when ________.
the amino acid sequence in a protein molecule is directly changed
the nucleotide sequence in an mRNA molecule is directly changed
the nucleotide sequence in a DNA molecule is directly changed
the expression of a gene changes without the DNA sequence being changed
Homework Answers
In bacteria and eukaryotes, a mutation is when the nucleotide sequence in a DNA molecule is directly changed.
When DNA nucleotides are changed, it leads to changes in the mRNA sequence which results in a change in the amino acid sequence of the translated protein leading to mutations.

1. If an mRNA carried a mutation that caused a difference in the amino acid sequence relative to the wild-type gene product, would the translation machinery recognize this and correct it? Explain. 2. Synthesis of mRNA (transcription) and protein (translation) proceed in an ordered manner, from one end of the molecule to another. What is the polarity of each of these processes? (Use the terms 5', 3', amino, carboxyl.)

DNA to Protein Describe the mutation that created the HbS allele: type of mutation, location of mutation on HbA sequence (# of bases from beginning of sequence), nucleotide change (from which base to which base?). Describe the effect of this mutation on amino acid sequence of beta-globin polypeptide chain: effect of mutation on codon, which amino acid was changed (# amino acids from beginning of chain), what was the amino acid change (from which amino acid to which amino acid?)...

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...
Which mutation has a change in the DNA sequence but no change in the amino acid sequence?
Question 12 Which mutation has a change in the DNA sequence but no change in the amino acid sequence? Question 4 Match the nucleotide pictures to their names.

Dystrophin is a protein that forms part of a vital protein complex that connects the cytoskeleton of a muscle fiber cell to the extracellular matrix. This connection strengthens and shapes the muscle fibers. Dystrophin is coded by the DMD gene. This is one of the longest human genes known, covering 2,300,000 base pairs (0.08% of the human genome) It is located in chromosome 21. The immature mRNA is 2,100,000 bases long and takes 16 hours to transcribe. It contains 79...
