Final answer:

The amino acid sequence for the mutated DNA sequence 'TAC ATC TTG GCG ACG ACT' would simply be methionine (Met), since the translation process starts at the start codon AUG and ends at the first stop codon, which in this case is directly after the start codon.

Step-by-step explanation:

To determine the amino acids of the mutated DNA sequence TAC ATC TTG GCG ACG ACT, first, we need to transcribe this sequence into mRNA and then translate it into a sequence of amino acids.

The complementary DNA sequence to the given template DNA strand is ATG TAG AAC CGC TGC TGA. The mRNA that would be transcribed from this DNA sequence would be AUG UAG AAC CGC UGC UGA.

Next, let's translate the mRNA sequence into the amino acid sequence. Using the genetic code:

  • AUG codes for methionine (Met)
  • UAG is a stop codon
  • AAC codes for asparagine (Asn)
  • CGC codes for arginine (Arg)
  • UGC codes for cysteine (Cys)
  • UGA is another stop codon

However, it's important to note that translation starts at the start codon AUG and ends at the first stop codon encountered. Therefore, the amino acid sequence for this mRNA is simply methionine (Met), since everything after the stop codon is not translated.

To conclude, the type of mutation can be determined by comparing the original and mutated sequences. Without the original sequence, it's not possible to define the exact type of mutation in this case.

Answer:

Tyr Ile Leu Ala Thr Thr

Step-by-step explanation:

In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of 20 amino acids and these amino acids are coded by a pair of three bases.

There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).

The given mutated DNA sequence will also code for some amino acid, that is as follows:

TAC - Tyr (Tyrosine)

ATC - Ile (Isoleucine)

TTG - Leu (Leucine)

GCG - Ala (Alanine)

ACG - Thr (Threonine)

ACT - Thr (Threonine)

Thus, The mutated DNA sequence TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
