Chapter 14, Problem 11RQ
How did Meselson and Stahl support Watson and Crick’s double-helix model?
- They demonstrated that each strand serves as a template tor synthesizing a new strand of DNA
- They showed that the DNA strands break and recombine without losing genetic material
- They proved that DNA maintains a double helix structure while undergoing semi conservative replication
- They demonstrated that conservative replication maintains the complementary base pairing of each DNA helix.

in DNA replication, if the template strand is 5’-ATCCGTGTAACCTT-3’, what is the sequence of the newly synthesized DNA strand? Write the sequence from 5’ to 3’.
DNA replication occurs by adding
(Note: NTPS = nucleotide triphosphates; dNTPs = deoxynucleotide triphosphates)
DNTPS to the 3' end of the template strand
NTPS to the 3' end of the daughter strand
DNTPS to the 3' end of the daughter strand
DNTPS to the 5' end of the template strand
NTPS to the 5' end of the daughter strand

- Single-stranded binding proteins (SSBPs) bind to single-stranded DNA at the replication fork and prevent formation of short hairpin sequences that would otherwise impede DNA synthesis. What sorts of sequences in single-stranded DNA might be able to form a hairpin? Write out an example of a sequence that could form a 5-nucleotide hairpin loop, and draw it.arrow_forwardWhich mechanism contributes to accuracy during DNA replication? Group of answer choices Base-stacking between nucleotides and the template DNA controls insertion of the correct nucleotide. Using primers increases accuracy because the first nucleotides in a new nucleic acid chain are more likely to be correct. The mismatch repair system recognizes an incorrect base-pair and corrects the mistake in both strands. All DNA polymerases have a 5′→ 3′ exonuclease activity which can remove incorrect nucleotides during replication.arrow_forwardKornberg showed that nucleotides are added to the 3' end of eachgrowing DNA strand.

- DNA is made of two strands that are antiparallel. If one strand runs from 3’ to 5’ direction the other one will go from 5’ to 3’ direction. During replication or transcription, whatever the process is, it will always follow the 5’ to 3’ direction using the 3’ to 5’ directed strand as the template strand. Therefore, if following is the DNA sequence 5’-CCG ATC GCA CAA-3’ Using this sequence as template after transcription no protein can be translated. Why?

What enzymes are used ?arrow_forwardSometimes DNA polymerase makes a mistake, and the wrong nucleotide is added to the growing DNA strand. Withregard to pyrimidines and purines, two general types of mistakes are possible. The addition of an incorrectpyrimidine instead of the correct pyrimidine (e. g. adding cytosine where thymine should be added) is called atransition. If a pyrimidine is incorrectly added to the growing strand instead of purine (e.g. adding cytosine when anadenine should be added), this type of mistake is called a transversion. If a transition or transversion is not detected by DNA polymerase, a mutation is created the permanently changes the DNA sequence. Though both types of mutations are rare, transition mutations are more frequent than transversion mutations. What are at least three explanations as to why this is the case?arrow_forward
