- During DNA replication, one of the new strands of DNA is synthesized continuously, while the other is synthesized as a number of separate fragments of DNA that are subsequently linked by DNA ligase. This is because O replication starts at many points on the chromosome RNA primers only anneal to one of the parental strands of DNA one of the parental strands is unwound slower than the other by helicase DNA polymerase III only synthesizes DNA in the 5' - 3' directionConsidening the structure of DNA, what kind of bonds hold one nucleotide to another within one side of the DNA molecule? O hydrogen O phosophodiester O lonic peptideIf a mutation occurred that prevented single stranded binding proteins from binding, the result would be: O Replication would not be initiated O DNA would be synthesized on the leading strand, but not the lagging strand Replicating would be initiated, DNA would unwind, RNA primers would be laid down, but DNA polymerase would not bind O The newly synthesized RNA would not be able to leave the DNA template Replication would be initiated, but RNA primers would not anneal to the DNA
- Help me pleaseDuring DNA replication, the function of RNA primers is to Group of answer choices serve as a binding site for DNA ligase separate the two strands of the double helix to open replication "bubbles" serve as starting points for DNA strand elongation by DNA polymerase in the 3' - 5' direction prevent new-separated strands of DNA from rejoining serve as starting points for DNA strand elongation in the 5' - 3' direction by DNA polymeraseWhat does i mean to say that extension by DNA polymerase III proceeds 5' 3'? The 5' end of a DNA polymerase molecule attaches to the 3' end of primase. DNA polymerase adds nucleotides to a growing strand, moving in the 5'-3' direction. O DNA polymerase seals nicks as it moves along a DNA strand toward the 3' end. DNA polymerase can only synthesize DNA at the 5' end of an existing strand of DNA. O O 0
- Given the following template DNA strand, what is the correct complementary DNA sequence? 3' CGC AGT GGA CAT TTC 5' O 5' GCG TCA CCT GTA AAG 3' O 5' GAA ATG TCC ACT GCG 3' O 5' GCG UCA CCU GUA AAG 3' O 5' GAA AUG UCC ACU GCG 3'The 5'-3' exonuclease activity involves all the following EXCEPT: o Both ribonucleotides and deoxyribonucleotides can be removed. O DNA repair can also be undertaken by this activity. o Groups of altered nucleotides can also be removed. o Removal of one nucleotide at a time in the properly base paired DNA. o Activity is possessed by both DNA polymerase I and IIIIf primase makes an error and incorporates an incorrect base in the nucleic acid primer, then why would this not be a problem given the DNA replication mechanism? O Primase only copies end sequences that will be protected by telomers The lagging strand utilizes a helicase to prevent replication errors O Primase can be error proofed using a domain of DNA polymerase O The RNA primer sequence is removed and not used as a template
- Why are Gyrase inhibitors good antibiotics to use therapeutically? DNA Gyrase is required by prokaryotes, but not eukaryotes, to complete chromosomal replication so it's a good target to inhibit. O DNA Gyrase is required by eukaryotes, but not prokaryotes, to complete chromosomal replication so it's a good target to inhibit. It's impossible to develop resistance against Gyrase inhibitors so they are always effective. O DNA Gyrase is required by both prokaryotes and eukaryotes to complete chromosomal replication so it's a good target to inhibit.Match the enzyme on the left with its role in DNA replication DNA polymerase I helicase DNA ligase DNA polymerase III topoisomerase primase 72 W w# 3 E $ 4 R % 5 T A 6 MacBook Pro Y & 7 U * 8 replaces primers with DNA connects Okazaki fragments to form a continuous strand of DNA synthesizes short RNA fragments used to initiate DNA synthesis Uses the 3'OH of an RNA primer to synthesize the leading strand and Okazaki fragments keeps DNA from getting tangled up ahead of the replication fork "unwinds" the DNA double helix at the origin and replication forks 1 ( 9 X 0 0 P + 11 NextEscherichia coli's chromosome has a replication origin called OriC.
