Which of the following would be the correct sequence of amino acids in the protein that this portion of the gene encodes?

- Shown below is a DNA coding strand. A base (*G*) mutates to Adenine (A). What will be the resulting amino acid sequence as a result of the mutation? What type of mutation occured? Hint: Determine the template, then first determine the amino acid sequence before the mutation, and then determine the amino acid sequence after the mutation. Show how you got your answer. 5' T-A-C-T-T-C-C-A-*G*-C-C-G-C-T-C 3'arrow_forwardSeveral different nucleic acids are involved in the process of getting a protein produced from a gene. DNA contains the "genetic code" for the protein. DNA is double-stranded, but only one strand is transcribed into MRNA. The MRNA then goes into the cytoplasm where it is translated into protein with the help of TRNA. At each stage of the process, there is base complementarity (A pairs with T/U and C pairs with G) between the nucleic acids involved to ensure the integrity of the DNA blueprint for the protein being produced. Therefore, some of the four strands of nucleic acids involved will match (except U replaces T in RNA) and some will have base complementarity. Indicate whether there is matching (1) or base complementarity (2) between the following nucleic acids. DNA sense strand and MRNA DNA sense strand and tRNA DNA antisense strand and MRNA MRNA and TRNAarrow_forwardAt least three types of RNA are required for protein synthesis. Compare and contrast mRNA, rRNA, and tRNA by moving the descriptions of their structure and function to the appropriate categories. Some phrases may describe all three types of RNA. mRNA in eukaryotes, can exist outside the nucleus acts as an enzyme for peptide synthesis composed of ribonucleic acid rRNA Answer Bank moves amino acids to the site of protein synthesis tRNA contains nucleotide triplets that code for specific amino acids has a convoluted structure with a three-base sequence called an anticodon moves genetic information out of the nucleus and into the cytoplasm mRNA, rRNA, and tRNAarrow_forward

It is about the flow of genetic information. It is an outdated theory that is no longer relevant. Transcription and translation are the two steps that facilitate the flow of genetic information.
