TACCCGTGCACG. If the T at the beginning of the sequence is deleted, what will be

Well, first the sequence would have to be transcribed because mRNA does not have a T nucleotide. Once it's been transcribed into AUGGGCACGUGC. If you take off the A, which was a result of the T at the beginning, all of the codons after that point will be changed. When it's translated and read to make protein, the translation will just go on longer until it reaches the STOP sequence.
