vvnicn the following statements are correct about the repair of a DNA duplex containing the sequence below that is grown INE coli (select all that apply)? Strand A Strand B GATCTAGCCGGCATCCGAT CTAGATCGGACGTAGGCTA Methyl ✔A. MutH cleaves Strand A O B. DNA repair will result in the bold A in strand B being replaced with a C O C. DNA repair will result in the bold G in strand A being replaced with a T ✔ D. Defect will not be properly repaired in dam(-) E coli O E. The mammalian repair system would also correct the mismatch shown based on the methylation status of the DNA

In Watson and Crick's model of DNA structure, the two strands of the DNA double helix are joined through   a. Ionic bonds   b. Hydrophobic interactions   c. Covalent bonds   d. Disulfide bonds   e. Hydrogen bonds

RNA primers are necessary in DNA synthesis because OA. primers mark the sites where helicase has to unwind the DNA. OB. the DNA polymerase enzyme can catalyze the addition of deoxyribonucleotides only onto the 3' (-OH) end of an existing strand. O C. RNA primase is the first enzyme in the replication complex. D. they are the source of nucleotides for DNA polymerases. 00 O E. DNA polymerase is unable to initiate replication without an origin. 5 p

I need help with a micro biology question involving DNA sequence and transcription. Below is a picture of the question that I need help on from my study guide.

DNA polymerase I functions in DNA replication to: O a. synthesize the RNA primer O b. O C. bind to single-stranded DNA and prevent it from reannealing O d. removes the RNA primers and fill in the gaps synthesize the leading and lagging strands synthesize the leading strand, but not the lagging strand e.

Based on the sequencing results above, what is the sequence of nucleotides as they were added by DNA polymerase to the DNA template? a/ATC-GCA-GTA b. TAG-TGC-CAT c. TAC-TGC-GAT GC-GA TAG-CGT-CAT L A EI la la اد ان YI

DNA STRAND IS 3’ TAC-AGC-ACT-CAG-TCA 5’a. what is the non-template/sense/coding strand?b. What is the arrangement of the m-RNA?c. What's the chain arrangement of the amino acids that will be made according to the order of the RNA?d. If on the non-coding strand of DNA there is suddenly one T base that sneaks into the 4th sequence (from the left), or causes a mutation, then how will the RNA be formed?e. What's the chain arrangement of the amino acids produced by this mutation?

A mutant DNA strand was transcribed then translated to proteins. a. What is the protein product of the mutant DNA strand? The sequence of the mutant strand is shown below: 5'-TGCCATAACTGTTCGTACTGGCAAATTGCC-3' 3'-ACGGTATTGACAAGCATGACCGTTTAACGG-5' b. The mutation altered the sequence of the wild type template DNA such that a degenerate codon for a basic amino acid in the wild type was converted to a non-degenerate codon resulting in the sequence for the mutant strand shown. What was the original amino acid? c. Compare the charges and pl of the mutant peptide and the normal (wild- type) peptide at physiological pH?

A fragment of DNA has the sequence 5'-ATCCGCT-3'. Following DNA replication, the complementary strand is 3'-TAAGCGA-5'. What type of mutation occurred? a. Frameshift b. Transversion c. Pyrimidine dimer d. Transition
