process to screen which cells actually contain the gene of interest

it is the molecular bi-layer of phospholipids with the proteins arranged in random

round organelles enclosed by single membrane

author writes the "essay of the principles of population"

who is the father of biology

allow fertilization but nonviable. hybrid zygote forms .

study of the geographic distributions of organisms.

transfer plasmid DNA

Logos means study of?

father of paleontology

structures that same appearance but different in function

study of development of the anatomy of an organism in it's initial phases of development

evolutionary process by which populations evolved to become district species

mating is physically impossible

it is the cell content outside the nucleus

aggregates the RNA and proteins synthesis in the cell proteins synthesized from free ribosomes are released as enzymes, protein from attached ribosomes are for the use within the cell

prevent fertilization and zygote formation

a change in the genes of plant or animal

serves as storage modification and packaging of secretory production in vesicles

appropriate vector or vehicle which would propagate the recombinant DNA

preserved remnants of once living organisms trapped in rocks, tar pits, frozen in ice or embedded in amber

who study the inheritance of acquired characteristics ?

genes are located in the chromosomes , which are made of DNA or deoxyribonucleic acid

fertilized egg fail to develop

preventing gene flow also known as other plase

bound sacs that function in storage and transport

flow of alleles

effect of change

cleavage of DNA by restriction(RES)

rapid diversification of life as well as the development of early land plants and the first amphibians

Geological eras that represents different periods in Earth's history

two species live in different areas/habitats

occurs during meiosis

what are the principal parts of a cell ?

longest and oldest geological era

in this technique, a genegun is used to fire DNA coated pellets on plant tissues

evolutionary biologists

F1 hybrids are normal F2 contains many weak or sterile individuals

closely related organism that are very similar and capable of producing fertile offspring

process that takes place in the nucleus of a dividing cell

living organisms shared numerous related biochemical molecules , such as DNA ,ATP, Amino acids and enzymes

Bios means?

process used to transfer plasmid DNA

structures that are specialized for plant cell or animal cell only

molecules that are used to build up and repair body parts

small vesicles containing powerful oxidative enzymes for inter converting organic molecules

branch of science that deals with plants

collection of evolutionary mechanisms

This mechanism of evolution was proposed

who write the " The origin of species"?

contains hydrolases,which catalyst the digestion of proteins, nucleic acids, some carbohydrates and fats

different seasons

powerhouse of the cell

follows a similar methodology as "heat shock treatment"

anatomy and development of organisms

often called age of dinosaurs

recombinant plasmid into a host cell

patterns of courtship is different

known as beside place . geographic neighbors

what's the meaning of (PMAT)

cellular process that results in the number of chromosomes in a gamete production cells

usually reduced and have no function in many organisms

egg and sperm prevent fertilization

serves as routes for the transport of materials between various parts of the cytoplasm rough(ER) with ribosomes smooth (ER)

composed of microtubules located in the centrosome just outside the nucleus

double membrane organelles found only in plant cells site of food production (photosynthesis) commonly called "food factory"

structures used for locomotion

substance that exhibits the properties and the activities of life also known as living material of the cell

human or animal in early stage of development

privacy structure of the protein

Age of mammals

rigid covering that protects the cell

study of structures of living things in a person's body

the most distinct organelle usually situated at the center of the cell bounded by double membrane

there is abnormal segregation of chromosomes during meiosis

also known as (join together)

who study the principles of geology?

also known as same place and initially occupy same habitat

structures which are different in appearance but have the similar function.
