A) DNA polymerase binds to a single-stranded DNA template (blue) and synthesizes a complementary ... From these data, the sequence of the newly synthesized DNA strand is determined, as shown ...

At this point, the target sequence is exposed to a solution that contains DNA polymerase and all of the nucleotides required for synthesis of the complementary DNA strand — along with one ...

Transcription is the process by which the genetic information in DNA is copied into a complementary RNA strand. RNA polymerase enzymes read the DNA sequence and synthesize messenger RNA (mRNA) ...

When a gene is to be expressed, the base sequence of DNA is copied ... form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note ...

on the complementary strand. Transversion mutations: A change from thymine to adenine (T → A) or guanine (T → G). Thymine deletions or insertions: The loss or gain of one or more thymine bases in the ...

The pegRNA binds to a matching sequence on the target DNA strand. The Cas9 nickase cuts the unbound complementary strand, creating a flap. The dangling DNA flap binds to a matching sequence on the ...

The enzyme is directed to its target--essentially any sequence along the genome--by hitching it to a strand of guide RNA (green) whose sequence is complementary to that of the DNA target.

Could viral infections play a role in Huntington's disease? Research suggests Apolipoprotein B mRNA editing catalytic ...

on one strand of the DNA and cytosine-thymine-guanine, or CTG, on the complementary strand—begin to repeat over and over, expanding to as many as 40 to 120 copies. The extended copies create ...
