A mutation occurred that caused a change in a mRNA sequence the mRNA codon UAC was replaced by codon UAA which statement describes the most likely outcome of the mutation
1.it will produce the same protein using a different set of codons
2.it will result in an incomplete protein that does not function properly
3.it will cause mRNA to attach a new amino acid chain during transcription
4.ot will change the bonding pattern between the amino acids joining together

2).it will result in an incomplete protein that does not function properly

Explanation: A codon is a triplet of nucleotide in an mRNA that codes for a particular amino acid. Some amino acids are specified by more than one codon. UAC and UAA are examples of codons found in an mRNA. UAC specifies amino acid tyrosine while UAA does not specify any amino acid and signals the end of translation, it is therefore called a stop codon. When a stop codon is encountered during translation, protein synthesis will be inhibited and this will result in a nonfunctional protein with incomplete amino acid sequence.
