2. MOLECULAR CHARACTER OF TAXANOMIC
CLASSIFICATION
• In taxonomic classification molecular
character refer to the unique, heritable
molecular trait or markers found in an
organism DNA , RNA, or PROTIEN . These
molecular markers help to classify or identify
the relationship between species by
comparing the similarities and differences in
their molecular sequences.

3. MOLECULAR MARKER
• Molecular markers are specific and
identifiable sequences of DNA , or RNA,
located in the genome of an organism.

4. MOLECULAR MARKER
• Molecular markers are used in molecular
biology , genetics and other fields to identify
unique features of an organisms or species. BY
comparing the presence or absence of a
specific molecular marker or variations in its
sequence with in a population or between
different species , researchers can infer the
genetic relationship among individual and
population.

5. M0LECULAR CHARACTER
• Molecular character are becoming important
in taxonomy especially in prokaryotes have
very simple organization . The most primitive
prokaryotes utilize the same
MACROMOLECULE and made use of common
metabolic pathways , which are present in
highest animals. Molecular techniques
utilizing sequencing of proteins, nucleic acids
and amino acids help in establishing
relationship between different species.

6. SOME IMPORTANT POINTS.
• Molecular characters provide a better way to
automatically differentiate the quality of
various animals, which were previously
present as zoological characteristics.
Using molecular character, relationships or
evolution can be examined qualitatively.
Molecular characters refer to specific DNA or
RNA sequences that are used to identify and
compare genetic individual or population.

7. SOME IMPORTANT POINTS.
• These sequences can be used to study the
evolutionary relationships among different
species to assess the genetic diversity of
population or to identify specific genetic traits
that may be associated with certain trait diseases.
• Molecular characters can include genetic markers
like single nucleotide polymorphisms or simple
sequence repeats.
