Molecular Biology
Molecular Biology is a subfield of biology and biochemistry
that focuses on the investigation of a wide range of biological processes at
the molecular level.
Amino acids, nucleic acids (DNA and RNA), proteins, carbohydrates,
and lipids are all included in molecular biology, as are their compositions,
interactions, structures, and roles in life processes.
Warren Weaver, an American scientist, came up with the term
"Molecular Biology" in 1938. According to the records, molecular
biology was first discovered in the early 1940s, and its fundamental
development occurred in 1953 when two molecular biologists named James Watson
and Francis Crick created the double-helical structure of the DNA molecule.

What exactly is molecule biology?
The study of living things at their molecular level, where
they are controlled and made, is called molecular biology. Additionally, it is
utilized for research and comprehension:
• The cell-to-cell molecular pathways
• How do living things
interact with populations?
• How do the biomolecules interact with proteins and nucleic
acids?
The fundamental significance of macromolecular mechanisms
like replication, transcription, translation, and other cellular functions will
be solidly established by studying molecular biology. Polymerase chain
reaction, electrophoresis, restriction digestion, blotting, cloning, and other
methods are among the most common in molecular biology.
The fundamental topics covered in this course are protein
synthesis in cells and nucleic acids (DNA, RNA). Biochemistry, cell biology,
genetics, and genomics are all closely related subfields of molecular biology,
which is a branch of biology.
Bioclimatology is a subfield of climatology that studies how
the physical environment affects living things over long periods.
Bioclimatology is a relatively new field of study, even though Hippocrates
addressed these issues in his treatise on Air, Waters, and Places 2,000 years
ago. During the 1960s, a growing concern about the deteriorating environment
was largely to blame for its rise to prominence as a distinct field of study.
The field of bioclimatology has a practically limitless
scope because virtually every aspect of climate and weather has some effect on
living things. However, studies of the influence of weather and climate on
small plant organisms and insects that cause diseases in humans, animals, and
plants are among the areas that receive greater attention than others; the
effects of weather and climate on normal and diseased human physiological
processes; the health effects of the microclimate in homes and urban centers;
and how the climate in the past affected how humans, animals, and plants
developed and spread.
Phylogenetics
In biology, phylogenetics studies how groups of living or
extinct organisms were related in the past.
History It has long been ingrained in human nature to organize the natural world into meaningful and valuable categories, at least since ancient Greece. The idea of a "Great Chain of Being," or scala naturae, emphasized a static concept of reality and depicted a hierarchy that began with matter and nature (like rocks) and moved up to humans, angels, and ultimately, God, was dominant in the West for close to 2,000 years.

Classificatory schemes have gradually abandoned postulating relationships between species based on either presumed essential traits or general physical similarity since Carolus Linnaeus and especially Charles Darwin.
Classificatory
schemes have also swiftly abandoned concepts like scala nature. In its efforts
to construct an objective depiction of evolutionary relationships between
organisms based on genetic, molecular, archaeological, and historical studies
with the specific purpose of explaining, predicting, and testing similarities
and differences between organisms, the field of phylogenetics takes a
functional and more scientific approach.
