1. Molecular biology - It is the study of biologyon a molecular level including the structure,

function, and makeup of biologically important

molecules such as DNA, RNA, and proteins.

The field of molecular biology involves many

other areas of biology such as biochemistry and

genetics (www.MedicineNet.com).

Etymology:Latin: molecula = small mass

Greek: bios = life; logos = science

Related Terms: Genetic engineering; chemicalgenetics

Interesting Facts:The term molecular biology first appeared in areport prepared for the Rockefeller Foundation

in 1938 by Warren Weaver, then director of the

Foundations Natural Sciences Division. Weaver

coined the term to describe a research approach

in which physics and chemistry would be used

to address fundamental biological problems

(Tropp, 2012).

Benefits: DNA fingerprinting analysis is used to

identify hereditary diseases in newborn babies. It

is also used in solving crimes.

Famous Case: Anna Anderson claimed to be

Russia's Grand Duchess Anastasia from the

1920s until her death in 1984. DNA

fingerprinting showed that her DNA did not

match the patterns of living relatives of the

Romanov royal family.

2. Biochemistry- It is the field of scienceconcerned with chemical substances and

processes that occur in plants, animals, and

microorganisms. It involves the quantitative

determination and structural analysis of the

organic compounds that make up cells (proteins,

carbohydrates, and lipids) and of those that play

key roles in chemical reactions vital to life

(www.merriam-webster.com).

Etymology: Bio + Chemistry

Greek: bios = life

Arabic: al kimia = art of transmutation

Related Terms: Biological chemistry,

molecular biology

Interesting Facts:The four main classes of molecules in

biochemistry are the ff:

Carbohydrates - breakdown of sugar into energy

Lipids - store energy membranes

Proteins - regulate cell process to form bones

and muscles

Nucleic acids - store and transmit genetics

information

We often hear that breast milk is best for babies,

but do we really understand the reasons why?Many of the body's systems that we take for

granted in adults are not yet fully functional innewborn babies. There are enzymes, which help

the baby to digest the fats and proteins present in

breast milk. Antibodies, similar to those of themother, help protect the baby from infection.

And the long chain polyunsaturated fatty acids

found in breast milk assist in the development of

the baby's brain.

3. Cytology Is a branch of biology dealing

with the structure, function, multiplication,

pathology, and life history of cells

(www.merriam-webster.com).

Etymology:Greek: kytos = hollow as a cell or container;

logia = study

Related Terms: Cell biology, cytopathology,

biopsy

Interesting Facts:The oldest stem cell donor is Erica Henderson

(UK) who, at 74 years of age, donated cells totreat her younger brother Paul, 69, who suffered

from leukemia. Medical rules state that the life-

saving cells can only be donated by people up to

the age of 70. However, after doctors found Mrs.

Henderson to be "100" fit she was allowed to go

through with the procedure. Her brother is now

in remission

Journal of Cytology

http://www.jcytol.org/

-The Journal of Cytology is the official

Quarterly publication of the Indian Academy ofCytologists. It is in the 25th year of publication

in the year 2008. The journal covers all aspects

of diagnostic cytology, including fine needle

aspiration cytology, gynecological and non-

gynecological cytology.

4. Hematology - Branch of medicine concerned

with the nature, function, and diseases of theblood. It covers the cellular and serum

composition of blood, the coagulation process,

blood-cell formation, hemoglobin synthesis, and

disorders of all these (www.britannica.com).

Etymology:Greek: haima = blood; logia = study

Related Terms: Hematopathology

Interesting Facts:Why do mosquitoes feed on blood? Adult

mosquitoes actually eat the nectar of flowers.But mosquito babies need protein, not sugar, to

grow. So their mothers feed on blood.

Bloodsucking mosquito moms find you by

sensing your body heat and breath. Then, with

their proboscis, they drill a hole through your

skin, into a capillary. Their saliva keeps the

blood from clotting while they drink.
