Check out a sample textbook solution- a. How many different DNA strands composed of100 nucleotides could possibly exist?b. How many different proteins composed of100 amino acids could possibly exist?arrow_forwardGiven the following DNA strand: TACAGAGATAACCGAATT A. Write the corresponding strand that would form the other half of the DNA molecule. B. Transcribe the original DNA strand (TACAGAGATAACCGAATT) and write the sequence of bases found in the resulting messenger RNA molecule. C. Translate your messenger RNA molecule and write the sequence of amino acids in the resulting protein (the genetic code is provided below).arrow_forwardYou have 2 solutions of DNA. Solution 1 contains single stranded viral DNA while Solution 2 has double stranded form of the same viral DNA. Both solutions contain 1 mg/ml of DNA. You then expose each of these solutions to UV light at 260 nm. Which of the following results would you expect to see after UV light exposure? a.Neither solution will absorb any UV light but the DNA in both solutions will be broken by the action of the UV light. b.Solution 1 will absorb less light than Solution 2 c.Solution 1 will absorb more light than solution 2. d.Nothing will occur. DNA can only absorb UV light if it is interchelated with ethidium bromide. e.Both solutions will absorb the same amount of light since their concentrations are the same.arrow_forward

If the mole % of G in this genome is 17%, what is the mole % of A?arrow_forwardSuppose that a length of double-stranded DNA is 2520 base pairs long. Calculate the number of helical turns if the DNA were in the B form, given that B-form DNA contains 10.5 base pairs B form: helical turns per helical turn. Calculate the number of helical turns if the DNA were in the Z form, given that Z-form DNA contains 12 base pairs per Z form: helical turns helical turn.arrow_forwardA.

- The sequence below shows one strand of DNA. Parts of the sequence are in capital letters to help you identify important features – capitalization does not affect the nucleotide indicated. 5’…atacaATGcATGTCAaCTAcg[a]agatccgTAGaTAACATtCATatc…3’ a. Underneath that strand write the sequence of the strand of DNA it would be paired with in a doublestranded helix. Use the single letter code A-adenosine, G-guanosine, T-thymine, U-uracil and C-cytosine and remember to label the 5’ and 3’ ends. b. Next, write the sequence of a possible mRNA transcript of the double stranded DNA above. Remember that an mRNA must be translatable by a ribosome into a protein. Be sure to indicate 5’ and 3’ ends. c. Using the genetic code, translate your mRNA into the appropriate protein. Write the amino acid sequence of the protein below the mRNA sequence in (b) and label the amino and carboxy terminals d. Suppose the bracketed, bold [a] were mutated to be a t. Write the new sequence of your mRNA transcript…arrow_forwardSuppose the following base sequence was found in a 20-base DNA polymer. 3'CAGTTACGGCTCCTAGGTTATAATTCGTTTC 5' a. What would be the first 5 bases at the 3' end of the complementary strand? b. What would be the first 10 bases at the 5' end of the complementary strand? c. Assuming the presence of the complementary strand, what is the percentage composition of the polymer with respect to the A-T base pair? with respect to the G-C base pair? d. In the given segment in problem 1, illustrate and indicate the direction of the synthesis of: i. a 5-nucleotide RNA primer ii. a 5-nucleotide Okazaki fragmentarrow_forwarda. Write the structural formula of GAC, a portion of DNA. Write the complementary strand adjacent to it so that the complementary bases are side by side. Connect the appropriate base pairs. b. Sticking to the convention of writing the nucleotide sequence in the 5'-3' direction, what is the nucleotide sequence of the DNA strand complementary to ATGCACCATGCT?arrow_forward
- For entertainment on a Friday night, a genetics professor proposed that his children diagram a polynucleotide strand of DNA. Having learned about DNA in preschool, his 5-year-old daughter was able to draw a polynucleotide strand, but she made a few mistakes. The daughter’sdiagram (represented here) contained at least 10 mistakes. Q. Draw the correct structure for the polynucleotide strand.arrow_forward11) Examine the following two DNA sequences. Sequence 1: ATGCGATGCTAGCAT Sequence 2: ATGCGATGATAGCAT If both of these sequences code for proteins, how might the function of protein 2 differ from the function of protein 1?
