Answer and Explanation:
UGA, UAG and UAA are the stop codons in the genetic code. During translation, these stop codons signal the end of the polypeptide chain. These codons do not code for an amino acid. Therefore they are called termination codons or nonsense codons. These stop codons have been called as ochre (UAA), amber (UAG) and umber or opal (UGA). Richard Epstein and Charles Steinberg revealed Amber (UAG). They named it amber while remaining two stop codons named as ochre (UAA) and opal (UAG) to maintain the theme of ‘colors names’. Stop codons release the new polypeptide chain from the ribosome, during protein synthesis. This happens because there are no tRNAs with anticodon corresponding to the stop codon.
We presented with several statements after the question. Only one of these statements are correct.
DNA replication is the process in which a single strand of DNA, acting as the parent strand, forms two new strands of DNA. DNA transcription is the process of copying the information of the DNA strand and delivering this information into a strand of mRNA. These processes may sound similar, but there are key differences. We must look at the building blocks of DNA and RNA. Both structures are composed of four different bases, however, only three of these bases are shared between structures and they each have a unique fourth base. In DNA, the fourth base is thymine and it is uracil in RNA. We already established that DNA replication forms new strands of DNA, which would use thymine by default. DNA transcription results in formation of mRNA which would therefore use uracil.
The correct statement from the choices provided is the following:
Thymine is used in replication while uracil is used in transcription.
