In E Coli Which Enzyme Catalyzes The Elongation Of A New ~ Lifestyle News

there was no real necessity for the addition of 5'-3' direction because DNA polymerase is the only enzyme that catalyzes the elongation of DNA strand on that list. primase adds RNA primers so that...DNA polymerase has two important restrictions: it is able to add nucleotides only in the 5′ to 3′ direction (a new DNA strand can be only extended in this direction). It also requires a free 3′-OH group to which it can add nucleotides by forming a phosphodiester bond between the 3′-OH end and the 5′ phosphate of the next nucleotide.55) In DNA replication in E. coli, the enzyme primase is used to attach a 5 to 10 base ribonucleotide strand complementary to the parental DNA strand. The RNA strand serves as a starting point for the DNA polymerase that replicates the DNA.DNA polymerases of prokaryotes can add nucleotides to both 3' and 5' ends of DNA strands, while those of eukaryotes function only in the 5' → 3' direction. Selected Answer: Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication.Enzymes known as DNA polymerases are responsible creating the new strand by a process called elongation. There are five different known types of DNA polymerases in bacteria and human cells. In bacteria such as E. coli, polymerase III is the main replication enzyme, while polymerase I, II, IV and V are responsible for error checking and repair.

In E. coli, which enzyme catalyzes the elongation of a new DNA strand in the 5' → 3' direction? DNA polymerase III Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine.Which enzyme catalyzes the elongation of a DNA strand in the 5' → 3' direction? A) primase B) DNA ligase C) DNA polymerase III D) topoisomerase E) helicase Eukaryotic telomeres replicate differently than the rest of the chromosome.Figure 2. Meselson and Stahl experimented with E. coli grown first in heavy nitrogen (15 N) then in 14 N. DNA grown in 15 N (blue band) was heavier than DNA grown in 14 N (red band), and sedimented to a lower level on ultracentrifugation. After one round of replication, the DNA sedimented halfway between the 15 N and 14 N levels (purple band), ruling out the conservative model of replication.D. each new DNA double helix consists of one old DNA strand and one new DNA strand E. each of the four DNA strands consists of some old strand parts and some new strand parts. which enzyme catalyzes the elongation of a new DNA strand in the 5' → 3' direction? A. primase In E. coli, what is the function of DNA polymerase III?In E. coli, which enzyme catalyzes the elongation of a new DNA strand in the 5' → 3' direction? O Primase O Helicase O DNA ligase O DNA polymerase III Celery stalks become stiff when placed in fresh water for several hours but they will become limp if you place them a 0.15 M salt solution.

c. DNA polymerase. it is the enzyme that catalyzes the addition of nucleotides complementary to the template strand. it may possibly most effective upload nucleotides on the 3' end of the DNA so it has to move in a 5' - 3' direction.

there was no actual necessity for the addition of 5'-3' direction because DNA polymerase is the best enzyme that catalyzes the elongation of DNA strand on that record.

primase adds RNA primers so that DNA polymerase III can start to add DNA nucleotides on DNA polymerase I replaces those RNA primers with DNA nucleotides

DNA ligase - creates the phosphodiester bonds of the newly shaped strands.

topoisomerase - untwists the DNA as helicase splits up the DNA by way of breaking the hydrogen bonds of the nitrogenous bases

helicase - splits double strand of DNA by breaking hydrogen bonds
