Strand DNA

Some articles on strand, dna:

Homologous Recombination - In Eukaryotes - Models
... Two primary models for how homologous recombination repairs double-strand breaks in DNA are the DSBR pathway (sometimes called the double Holliday junction model) and the synthesis-dependent strand annealing (SDSA ... After a double-strand break occurs, the MRX complex (MRN complex in humans) binds to DNA on either side of the break ... Next a resection, in which DNA around the 5' ends of the break is cut back, is carried out in two distinct steps ...
Okazaki Fragments
... Okazaki fragments are short, newly synthesized DNA fragments that are formed on the lagging template strand during DNA replication ... They are complementary to the lagging template strand, together forming short double-stranded DNA sections ... the two Okazaki fragments into one continuous newly synthesized complementary strand ...
Telomere Shortening
... in part because of the end replication problem that is exhibited during DNA replication in eukaryotes only ... Because DNA replication does not begin at either end of the DNA strand, but starts in the center, and considering that all known DNA polymerases move in the 5' to 3 ... On the leading strand, DNA polymerase can make a complementary DNA strand without any difficulty because it goes from 5' to 3' ...

Famous quotes containing the words dna and/or strand:

    Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.
    William Gibson (b. 1948)

    We all have reasons
    for moving.
    I move
    to keep things whole.
    —Mark Strand (b. 1934)
