Vocab Flashcards
Proteins
Large biological molecules or macromolecules consisting of one or more long chains of amino acid residues
Starches
A carbohydrate consisting of a large number of glucose units joined by glycosidic bonds
Concentration Gradient
A measurement of how the concentration of something changes from one place to another
Organelle
Any number of organized or specialized structures within a living cell
Amino Acids
A simple organic compound containing both a carboxyl (-COOH) and an amino (-NH2) group
Synthesized
To produce substance by combining chemical precursors
Anaerobic Respiration
Respiration without oxygen
Vascular Tissue
Plant tissue that transports nutrients and water throughout the plant (as veins and arteries are to animals)
Codons
A sequence of 3 DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis
Heterozygous
A cell containing 2 different alleles of a gene
Homozygous
A cell containing 2 identical alleles of a gene
Restriction Enzyme
Enzymes that cut a DNA molecule at a particular place
Gel Electrophoresis
A method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size in charge
Genetic Engineering
The process of manually adding new DNA to an organism
Phenotypes
The physical outcome of gene combinations
Ultraviolet Radiation
Radiation in the part of the electromagnetic spectrum where wavelengths are just shorter than those of ordinary, visible violet light but longer than those of x-rays
Independent Assortment
When two or more characteristics are inherited, individual heredity factors assort independently during gamete production, giving different traits of equal opportunity of occurring together
Asexual Reproduction
Motive reproduction by which offspring arise from a single organism and inherit the genes of that parent only
Regeneration
The natural renewal of a structure, as of a lost tissue or part
Recessive Alleles
A trait expressed only when the determining allele is present in the homozygous condition
Phenylketonuria (PKU)
A birth defect that causes an amino acid called phenylalanine to build up in the body
Mutual Symbiosis
Both individuals benefit from the relationship
Parasitism
A form of symbiosis in which one organism (parasite) benefits at the expense of another organism (host)
Gymnosperm
A group of vascular plants from seeds are not enclosed by a ripened ovary (fruit)
Xylem
The vascular tissue in plastic and asked water and dissolved nutrients upward from the root; helps form the woody element in the stem
Imprinting
Process where a young animal follows the characteristics of his/her mother after hatching
Sugar
Any monosaccharide or disaccharide, used especially by organisms to store energy
Phosphate Group
A functional group/radical comprised of phosphorus attached 4 oxygen, and with a net negative charge, represented as PO-4
