Document Summary

This forms the backbone : antiparallel arrangement allows proper base pairing. The two strands in the original molecule separate, with each serving as a template for a newly synthesized strand. At the beginning of g1 phase, 6 dna molecules are present in this cell. G2 phase, 12 dna molecules are present in this cell. C. helpful to know how interphase and dna replication work simultaneously at each stage. 26. describe how the dna molecule itself acts as a template for accurate replication. a. before replication of dna template is possible, need: i. Origin of replication: bubble where dna replication happens. Rna primer, primase- rna primer needs to be in place before copying begins. V. dna polymerase- enzyme used for copying the template strand, replaces rna primer with dna contains one original template. Semiconservative model of replication- each replicated double helix: dna polymerases c, match the right monomers with the template ii. iii.

Related Questions

Respond to each sentance with true or false regarding the replication of DNA:

Complementary base pairing relies on the number of hydrogen bonds that each base can make.

In a single nucleotide, the phosphate group is attached to the 5' carbon of the sugar unit.

The antiparallel arrangement of double-stranded DNA is due to the phosphate group being bonded to the 3' carbon on one strand and the 5' carbon on the complementary strand.

The phosphate attached to the 5' carbon of a given nucleotide links to the 3' -OH of the adjacent nucleotide.

The -OH group on the 3' carbon of the sugar unit is the attachment site for the nitrogenous base.

Read the following statements carefully and determine which are true and which are false.

i) The energy required to synthesize nucleic acids comes from the nucleotide building blocks themselves.
ii) The "groove" in the structure of double-stranded DNA allows binding interactions between proteins and particular base sequences.
iii) In double-stranded DNA, the two strands are wound around one another in a right-handed helix.

i) & ii) are true, and iii) is false.

i) & iii) are false, and ii) is true.

i) is false, and ii) & iii) are true.

All three statements are false.

All three statements are true.
