If the sequence on the DNA molecule calls for a protein with the following DNA codons: 1) What would be the base sequence on mRNA? 2) What would be the base sequence on tRNA? 3) What would be the amino acid sequence of the protein being made? DNA -> TAC GGC CAT GTA ATA ACT mRNA -> tRNA -> amino acid sequence -> The statements listed below are the events in protein synthesis. Put the statements in the order in which they occur. (1 = first step - 6 = last step) 3 mRNA attaches to a ribosome. 5 Newly arriving amino acids are connected to the growing polypeptide by peptide bonds. 2 The RNA is sent to the cytoplasm in the form of mRNA.

So, the mRNA sequence would be: AUG CCG GUA CAU UAU UGA 2) The base sequence on tRNA would be the complement of the mRNA sequence. So, the tRNA sequence would be: UAC GGC CAU GUA AUA ACU 3) The amino acid sequence of the protein being made would be determined by Show more…

Determine the protein's amino acid sequence that would be produced by expression of this segment of DNA shown below (sense strand). Use the information below to find the gene signal and translate the bases into mRNA and then protein. Determine which ATG/AUG to use by finding one that is downstream of the Shine-Dalgarno sequence. What is that? Read on. The Shine-Dalgarno (SD) sequence is a ribosomal binding site in prokaryotic messenger RNA, roughly located around 8 bases upstream of the start codon AUG. The RNA sequence helps recruit the ribosome to the messenger RNA (mRNA) to initiate protein synthesis by aligning the ribosome with the start codon. The Shine-Dalgarno sequence exists both in bacteria and archaea. It is also present in some chloroplast and mitochondrial transcripts. The six-base consensus sequence of the Shine-Dalgarno is AGGAGG. Sense strand of DNA: 5'-ATGTTATAAGTGGAAAGGAGGGGTTATGCCTTGAAAATGTCATAGTCCGTACGT-3' A) Met – Leu B) Met – Pro C) Met – Ser

Below is the sequence of an mRNA molecule. Assuming there were no introns, 1. Write the corresponding DNA sequence below 2. How many amino acids long would the protein product of translation be for this mRNA? 3. How many tRNA molecules would be involved in making this protein? and Briefly describe the three things that occur before a mature messenger RNA is exported from the nucleus

The base sequences in mRNA that code for certain amino acids are Glu: GAA, GAG Val: $\quad$ GUU, GUC, GUA, GUG Met: AUG Trp: UGG Phe: UUU, UUC Asp: GAU, GAC These sequences are complementary to the sequences in DNA. a. Give the corresponding sequences in DNA for the amino acids listed above. b. Give a DNA sequence that would code for the peptide trp-glu-phe-met. c. How many different DNA sequences can code for the tetrapeptide in part b? d. What is the peptide that is produced from the DNA sequence T-A-C-C-T-G-A-A-G? e. What other DNA sequences would yield the same tripeptide as in part d?
