What is the mRNA synthesized from the DNA strand? B. What is the amino acid sequence that is then translated from this mRNA strand? 2. Use the following DNA stand: TAC TTG GCC ACG GAC TAA CAT GCA A. What is the complementary DNA strand of the above DNA strand? B. Using the complementary DNA strand,...
A single mutation has occurred in the following DNA sequence. 5' ATG TTC CAG CCA 3' wild-type (normal) sequence 5' ATG TTC TAG CCA 3' mutant sequence a) Identify and classify the mutation according to its molecular structure (i.e., insertion, deletion base substitution (transversion), or base substitution (transition)). Briefly explain why you selected this classification. b) Identify and classify the mutation according to its functional effects (i.e., frameshift, missense, nonsense, or silent). Briefly explain why you selected this classification.
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...
