    Hello please please help !! Thank you!! Please and thank you soo much!!! Question Completion Status: Question 10: The genetic code consists of 64 triplets of nucleotides (called codons). Each codon (with the exception of the 3 stop codons) encodes for one of the 20 amino acids used in the synthesis of proteins. This produces some redundancy in the code as most amino acids are encoded by more than one codon. One codon, AUG serves two related functions: it signals...

    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...
