Estimating the age of fossils involves looking at their physical positions in sedimentary rocks () and radiometric isotope techniques ()

Relative dating and absolute dating

Coined the phrase "ontogeny recapitulates phylogeny," suggesting the false claim humans start as star fish, then progress through a series of developmental stages that retrace the lower vertebrates groups before becoming human

havetheir own set of DNA, separate from that of the cell nucleus

Mitochondria

have their own genomes

Chloroplasts

Cells reproduce by dividing primarily through two process...

Mitosis and Cytokenis

Cytoplasm division

Cytokinesis

normally prevent the uncontrolled growth and division of cells and tissues

Tumor-suppressor genes

are primarily factors contributing to cancers

mutation

typically involves the production of oxidative metabolic by-products such as molecular variants of oxygen, which may damage the DNA, RNA, proteins and mitochondria

Free radical formation

those occurring in tissues outside of the egg or perm , could lead to diminished function; skin and connective tissues lose resiliency

somatic mutations

suggests that there are "biological clocks' or pacemakers that commence at birth and simply slow and stop, ending in death

Pacemaker theory

making exact copies of genes

Gene cloning

Restriction enzymes create DNA fragments with the gene of interest.
DNA fragments are fused with DNA from a bacterium (palsmid)

Recombinant DNA

use of reproductive cloning to create human embryos to procure stem cells, which have potential to develop into adult tissues(may create treatment to diseases)

Therapeutic cloning

uses computer/statistical applications to access large database concerning DNA/gene/protein information

Bioinformatics

treating diseases and injury in umas onvolving the use of harmless retro virus vectors (or other entry mechanisms) that posses the enzyme reverse transcriptase, allowing the to insert genetic information into DNA

Gene therapy

research involving gene transfer in non-human organisms has been much more extensive

transgenic and genetically-modified plants and animals are becoming more common

Genetic engineering

is an extremely specific response typically involving the production of antibodies

Specific immunity

involves receiving antibodies or antiserum from other source

Passive immunity

are hypertensive tissue reactions to part of the specific immune response

Allergies

sever allergic reactions can lead to _______ which may be life-threatening

anaphylactice shock

is a condition in which cells of the specific immune response attack healthy tissues
