Sentence examples for a pair of replication from inspiring English sources

Only licensed origins containing MCM proteins can initiate a pair of replication forks, and once initiation occurs at an origin, the bound MCM proteins are displaced so that the origin cannot fire again [ 46].

We wrote PERL scripts to extract sequences for each region between a pair of replication origins and further prune them to only consist of non-coding nucleotides and the synonymous third codon position nucleotide, corresponding to an 'A' or a 'G'.

As it requires far fewer resources to assemble a licensed origin than it does to initiate a pair of replication forks (both of which probably comprise in excess of 50 polypeptides in addition to MCM2 7), it is clearly preferable to use inefficient origins, most of which will remain dormant.

These DNA sequences are found at multiple sites on each eukaryotic chromosome and direct the assembly of a bidirectional pair of replication machines, or replisomes, that replicate the DNA on both sides of the origin.

Analysis of living cells that have only a single pair of replication forks, with a complete round of replication occurring in the absence of division, has shown that different replisome reporters colocalize and mark both active and stalled replication forks.

To be a self-replicator, a molecule has to replicate both its exact and complementary copy because replication is complementary (the unit of replication is a pair of complementary sequences).

In Joyce's experiment it was found that a single replicating RNA molecule was relatively ineffective at self-replication, but a pair of similar RNA molecules, neither self-replicating but each helping the other replicate, worked way better.

To investigate the effects of the NS3 gene during viral DNA replication, a pair of primers was designed for amplifying NS3 gene of Bombyx mori densovirus (China isolate).

Defining the rate of DNA synthesis of each pair of replication forks as kΛ, we can write (10) ∂ Λ ∂ t = k Λ F. Assuming that kΛ is constant, and normalizing so that Λ = 1 is the length of one full chromosome, we have kΛ = 1 /C. Figure 2 summarizes the ingredients of the model.

At each eukaryotic replication origin, a pair of replisomes travels in opposite directions from the origin (Masai et al. 2010) and will encounter replisomes coming in the opposite direction as well as other obstacles such as nucleosomes, DNA barrier elements, transcription factors, transcribing RNA polymerases, and damaged DNA, as well as chromosome ends (Tourriere and Pasero 2007).

Here, one genotype consists of a pair of complementary sequences (for this is the unit of replication); thus, we obtain 2000 pairs of complementary sequences.
