- In cells, proteins are synthesized from a gene sequence via the process of transcription and translation. Which of the following complementary base pairings would you observe during the synthesis (the making) of a prokaryotic protein? [I am looking for the complementary base pairing(s) you would see as you go from a gene to a protein. Note that it is prokarryotic protein and not eukaryotic protein].

All of 1, 2, 3 and 4 are correctarrow_forwardFor each of the following items, fill in either the DNA strand, the MRNA codons, the tRNA anticodons, or the amino acid sequence that have been left blank. If several sequences might work, choose only one. Furthermore, circle the start and the stop codons of each mRNA sequence. 1.

What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forward
- In the gene-coding sequence shown here, which of the following events will produce a frameshift after the last mutational site? a. insertion of an A after the first codon b. deletion of the second codon (AAA) c. insertion of TA after the second codon and deletion of CG in the fourth codon d. deletion of AC in the third codonarrow_forwardIn RNA, an atypical base pair is able to form between guanine and uracil. This base pair allows a single tRNA molecule to recognize more than one codon using its one anticodon sequence. It requires a shift in position of the two nucleotides. Guanine and uracil come together in this unusual pair via 2 hydrogen bonds. Based on what you know about hydrogen bond formation and base pairing, draw a guanine nucleotide and a uracil nucleotide hydrogen bound to one another.arrow_forwardConsider this nucleotide sequence of DNA strand in the image provided. If this strand is the sense strand, Give the correct nucleotide sequence of the RNA produced after transcription. If the RNA formed in #1 is already a functional mRNA and will be used to synthesize proteins, how many codons are present here that will actually code for amino acids? What is the sequence of the stop codon in this mRNA? What is the sequence of the 3rd codon in this mRNA? What is the sequence of the last codon in this mRNA that actually code for an amino acid?arrow_forward
- Amino acids are translated from mRNA codons and each codon is made up of three nucleotide bases. How might an extra single base INSERTION into the second codon of a coding sequence of a gene affect the amino acid sequence of the protein encoded by the gene? (Hint: You may want to write out a made-up example of an insertion like the one described above) The entire amino acid sequence would shift and be changed. O A single amino acid would change only. O The mutation may have no effect on the amino acid sequence. O A single extra amino acid would be present in the protein. O All of the above are possible outcomes.arrow_forwardLike mRNA, tRNA has a ribose sugar, U instead of T, and is single stranded. Unlike mRNA, which remains a long single strand of nucleotides, tRNA folds so that some areas pair up. The resulting structure has an anticodon on one end and a site for an amino acid to attach on the other end. There is base complementarity (A pairs with U and G pairs with C) between an mRNA codon and tRNA anticodon.If the amino acid lysine attaches to a tRNA, which of the following anticodons could be at the opposite end of the tRNA molecule? a. UUU and UUC b. AAA and AAG c. AGA and AGU d. UCU and UCAarrow_forward(a) Write the complementary base sequence for the matching strand in the DNA section shown below:. 5’ – A T G T T A C T A G T C – 3’ (b) The following section of DNA is used to build an mRNA for a protein: 3′—AAG—CTT—CTC—5′. What is the corresponding mRNA sequence?arrow_forward
- The 3 major forms of RNA (mRNA, tRNA, & rRNA) interact during translation. b) Which of the 3 types of RNA might you expect to be the least stable? Why? c) Compared to the average stability of mRNA in E.coli, is mRNA in a typical human cell more stable or less stable? Why?arrow_forwardWhich of the following describe how the order of nucleotide bases along a gene in the DNA ultimately determines the primary structure of a protein and how the primary structure ultimately determines the three-dimensional shape and function of the protein coded for by that gene. A Certain amino acids in a protein interact with other amino acids in that same protein and so the order of amino acids ultimately determines the 3-dimensional tertiary structure of that protein. B The order of nucleotide bases along the DNA is transcribed into complementary tRNA which is translated into the correct amino acid sequence for the protein by mRNA. C The order of nucleotide bases along a gene determines the order of amino acids in the resulting protein. The order of amino acids in the protein is called its secondary structure.arrow_forwardThe 3 major forms of RNA (mRNA, tRNA, & rRNA) interact during translation. c)Compared to the average stability of mRNA in E.coli, is mRNA in a typical human cell more stable or less stable?
