presence of stop signal within transposon.
Transposons help bacteria adapt to new environments, therefore generating genetic diversity.
transposable genetic constituents in maize or transposons.
Being exposed to environmental radiations and chemicals causes gene mutation. Viruses, transposons and errors that occur during meiosis (DNA replication) also affect the genetic code.
The chemical responsible for genetic information in a cell is DNA
The most important source of variability in bacteria is mutation.
Practically every genetic disorder that includes physical characteristics affects facial features. The term is dysmorphic facial features genetic disorders.
Genetic traits are variations of features passed on to offspring from there parents.
Genetic make up and consistancy in morphological features
Meiosis is responsible for genetic variation
recombinant DNA
People have differences in the genes that map facial features. This is why identical twins (twins with the same genetic code) have the same facial features (disregarding non-genetic factors such as scars).
The genetic mutation responsible for Marfan was discovered in 1991.
