- What determines the nucleotide sequence of the newly synthesized strand during DNA replication? the particular DNA polymerase catalyzing the reaction the relative amounts of the four nucleoside triphosphates in the cell the nucleotide sequence of the template strand the primase used in the reaction the arrangement of histones in the sugar phosphate backbonearrow_forwardThe synthesis of new DNA requires energy. Where does this needed energy come from? The DNA polymerase reading the old DNA strand. The triphosphate nucleotide that is being added to the new DNA strand. The carbohydrates that the bacteria cell eats. The breaking of the hydrogen bonds between the opposite DNA strands.arrow_forwardDuring DNA replication, the enzyme called _______ unwinds the DNA double helix structure, separating the two strands of DNA apart. These two DNA strands serve as templates for synthesis of new DNA. The two strands are held apart by ______ , stabilizing the open "bubble" configuration.arrow_forward
- DNA replication is called semi-conservative because ___ (all, all or none) of the two new strands of DNA is old DNA from the original DNA molecule and ___ (all, all or none) is new DNA.arrow_forwardDuring DNA replication, a template strand is used to synthesize a new "daughter" strand of DNA. Below is a sequence of a short segment of DNA. Provide the base sequence in the complementary strand and label all ends. 5’ A A T C G T A A G C T 3’arrow_forwardWhy is an RNA primer necessary for DNA replication? The RNA primer is necessary for the activity of DNA ligase. The RNA primer creates the 5â and 3â ends of the strand. DNA polymerase can only add nucleotides to RNA molecules.
