Before a cell divides, its DNA is replicated (duplicated.) Because the two strands
of a DNA molecule have complementary base pairs, the ... If the two strands of a
DNA molecule are separated, each can be used as a pattern or template to ...
Each template and its new complement together then form a new DNA double
Sep 30, 2003 ... DNA, molecular structure, The double helix, James Watson, Francis Crick, ... in
opposite directions and that the molecule had a specific base pairing. ... pairing
this gives rise to two identical daughter copies from each parent molecule. ...
Scientists have also been able to insert new bits of DNA into cells that ...
DNA and its close relative RNA are perhaps the most important molecules in
biology. ... DNA therefore has two essential functions: replication and expression.
... long, and it folds up by complementary base pairing to form a clover-leaf
structure. ... every cell division, so that one identical copy can go to each
Feb 5, 2011 ... CHROMOSOMES; How is DNA passed on to new cells? ... This gives us a
complete DNA molecule: a structural backbone of deoxyribose ... Because every
base pair in the double helix must match its pairing partner (A with T, ... Because
DNA has already replicated, each chromosome appears as a joined ...
Because many identical RNA copies can be made from the same gene, and each
... All of the RNA in a cell is made by DNA transcription, a process that has ... to
expose a new region of the template strand for complementary base-pairing. ......
Instead, the mutation typically creates a new pattern of splicing (Figure 6-35).
During DNA replication the cells replicate their DNA in two identical copies from
the original one. ... The mechanism of base pairing take place when each strand
of the DNA has all the ... each molecule will have one original strand and one
new strand (Figure 3). ... Figure 4: The three alternative patterns for DNA
Each nucleotide in DNA has a sugar component joined to a phosphate ... The two
