384 Answer all the questions below please! Required: At least 3-4 sentences for each answer Write answers in your own words (don't copy the answers directly) Choose one of the questions below to write a follow-up question Structure and Function of DNA and RNA Q2.1- Hydrogen bonds can form with bases on the opposite DNA strands in the double helix, or between the bases and H2O in the single stranded conformation. Considering that the double helix is the most stable conformation in water, how does this observation support the conclusion that base stacking contributes more to helix stability than interbase hydrogen bonding? Amino Acids and Peptides Q2.2-Using Table 4.3, list the amino acids that will carry a net charge at pH 7 within a protein. What is the charge at pH 7 for each of the amino acids you have listed (-2, -1, +1, etc.)? What is the net charge at pH 7 of the tetrapeptide shown in figure 4.17?

Can you please check my answer and make sure it is correct. Question: List the ingredients of master mix, and state the purpose of each ingredient. Answer: Taq DNA polymerase This enzyme synthesizes the complementary strand of the DNA template after attaching to the primer. This means that it adds on free nucleotides to the existing strand, but helps speed up the covalent bonding between these newly added nucleotides. This enzyme is also thermally stable meaning that it can withstand the hot temperatures needed for PCR to occur. This hot temperature is needed for the denaturation step when the double stranded DNA has to be unwound and separated into two strands. Individual building blocks of DNA (either free nucleotides A, T, C, and G or dNTP’s) These nucleotides are needed to build the complementary strand of DNA A special buffer to maintain the optimal pH, salts, and MgCl2 These buffers help maintain a good pH that doesn’t become too acidic or basic for Taq DNA polymerase to…

Can you please check my answer and make sure it is correct? Question: Why are hydrogen bonds so vital to the structure of DNA? Hydrogen bonds are important for DNA because they are the bonds between the bases and help DNA form into its double-stranded shape. These bases include adenine, thymine, guanine, and cytosine. Adenine forms two hydrogen bonds with thymine and guanine forms three hydrogen bonds with cytosine. The resulting double-strands are held together by hydrogen bonds which is an important characteristic for DNA. These weak bonds are stable, but can be separated when it is necessary. This process is necessary during DNA replication, when a duplicate copy of DNA is being made or during the denaturation step in PCR.

Question 3 List three characteristics of the structure of the DNA molecule. Question 4 Suppose you have a 5'-AGAGTGCGTA-3' sequence on one strand of the DNA. What is the base sequence that should appear on the other complementary strand of the DNA?
Write out the DNA sequence using the following instructions: This is a double stranded DNA hydrogen bonding with each other following the principle of complementary base-pairing Each strand contains ten nucleotides Each strand contains all four different types of nucleotides You should indicate clearly the directionality of each strand in your answer You do not need to draw the full nucleotide structure. Use the one-letter code (A, T, G, C, or U) to represent each nucleotide
ANSWERS 1-3 were answered but I need 4 and 5 answered please. Three parts are solved in case of interlinked question as per our company policy. If you want assistance with other parts, please post separately. The DNA is made up of deoxyribonucleotide sub units. It is the genetic material. Step 2 The deoxyribonucleotides consist of deoxyribose sugar, phosphate group and nitrogenous bases. Nitrogenous bases are adenine, guanine, thymine and cytosine. Answer 1) The sequence of template strand in 3' to 5' sequence is: 3' TACCCGCCAGCCTACATC 5' Answer 2) The mRNA strand is complementary to the template strand. The RNA polymerase synthesises mRNA. The A, U, G and C are present in mRNA with respect to the T, A, C and G in DNA. The mRNA sequence is: 5' AUGGGCGGUCGGAUGUAG 3' The mRNA sequence in form of codon is: 5' AUG GGC GGU CGG AUG UAG 3' The codon is made up of three nucleotides. Answer 3) The mRNA codon chart helps to find the sequence of amino acid from a codon. The start…
Please answer all correctly. Thanks. 1. When DNA helicase is active, the result is: - annealing of RNA primers to the DNA - formation of phosphodiester bonds - formation of hydrogen bonds - separation of the two strands of the double helix - swivelling of the single separated strands of DNA 2. During DNA replication _______ aids in relieving pressure from DNA supercoiling. - helicase - RNA polymerase - ligase - topoisomerase
During proofreading, which of the following enzymes reads the DNA? primase topoisomerase DNA pol helicase
I need help with a bilogy question, Since the first nucleotide cannot be directly linked in a newly synthesized strand in DNA replication, _______ is required. an RNA primer DNA polymerase ligase a DNA primer
I just want to double check my answers are in bold for both questions thank you!Supercoiling of pure circular DNA is a result of ________. A. underwinding or overwinding of the helix B. entanglements because of the long length of the strands C. the lack of associated histones D. the activity of exonucleases It is easier to melt DNA richer in AT than GC because A. it is more heat sensitive. B. there is one less hydrogen bond in an AT base pair. C. the helix pitch is longer in AT rich regions. D. All of the above
