Sequences in mrna, such as uga, uaa, or uag, that tell a ribosome when to stop making a new protein are known as

The correct answer is-

Stop codon.

Explanation:

Codon can be described as a sequence of three nucleotides that is present in DNA or RNA and codes for a particular amino acid (building block of protein).

The information carried by mRNA (messenger RNA) in the form of codons, help in the formation of protien at the site called ribosome.

Stop codon does not code for any amino acid and when it is encountered by ribosome, the process of protein synthesis is terminated.

In other words, stop codon (such as UGA, UAA, or UAG) tells a ribosome when to stop making a new protein.

Thus, stop codon is the right answer.
