![]() ![]() A genetic clone can also refer to an organism that is a genetic copy of the original - produced using various in vitro techniques.ģ4 Animation, 34 Video 39 Animation codon Three bases in a DNA sequence that encodes the type of amino acid to be placed in the protein. DNA molecules can be cloned using bacteria or viruses as hosts. Humans have 46 chromosomes.Ĩ Animation, 8 Bio 9 Animation, 9 Video, 9 Bio 10 Animation, 10 Video, 10 Bio 11 Animation, 11 Video, 11 Gallery, 11 Bio 29 Animation, 29 Video, 29 Problem clone Refers to a replica. Joined at the centromere during mitosis and meiosis.ħ Animation 8 Animation 31 Animation chromatin Refers to the combined DNA and protein material that coils up to form chromosomes.Ģ9 Animation chromosome Chromosomes are packages of DNA found in the nucleus of cells. ![]() During mitosis this region connects the sister chromatids and attaches the spindle fibers that draw the separated chromosomes to opposite poles.ħ Animation 8 Animation 39 Animation chromatid Each of the two daughter strands of a duplicated chromosome In eukaryotic cells, the cell cycle has two periods: interphase, when the cell grows and duplicates its DNA (G1, S and G2 phases), and mitosis (M phase), when the cell splits into two daughter cells.ģ8 Animation Central Dogma Theory developed by James Watson and Francis Crick to describe the process of protein production: DNA to RNA to protein.Ģ1 Animation, 21 Bio 25 Animation, 25 Bio centromeres Regions of chromosomes made up of non-coding, highly repetitive DNA. The pairs are held together by hydrogen bondsġ9 Animation BRCA1/BRCA2 Mutations in the BRCA1 and BRCA2 tumor suppressor genes are linked to inherited breast and ovarian cancer.ģ6 Animation C cDNA library A library composed of complementary copies of cellularģ6 Animation 39 Animation 40 Animation cell cycle The process of cell division and replication. The bases that make up DNA pair with each other: A to T and G to C. Altered forms are used as vectors for cloning DNA.ġ8 Animation 27 Animation 39 Animation base pairing Discovery made by James Watson that was key in solving the structure of DNA. (see Escherichia coli)ġ7 Animation, 17 Bio 18 Animation 27 Animation, 27 Bio 28 Animation 30 Animation 40 Bio bacteriophage (phage or phage particle) A virus that infects bacteria. There are 20 different amino acids used to make up proteins.ġ5 Animation, 15 Video, 15 Bio 16 Animation apoptosis (cell death) The natural process of programmed cell death as part of normal growth and development.ģ8 Animation, 38 Problem Antennapedia A homeotic mutation of Drosophila, where a pair of legs replaces the antenna.ģ7 Animation, 37 Gallery autosome A chromosome that is not involved in sex determination.ģ9 concept B bacterium/bacteria A single-cell prokaryotic organism. The flower color gene in this case has two alleles, one for white and the other for reddish-purple.Ģ Animation 4 Animation, 4 Problem 5 Animation, 5 Problem 11 Animation 16 Animation amino acid A class of molecules that are the building blocks of proteins. A mutation on the HGD gene causes the condition.ġ3 Bio, 13 Problem 16 Animation allele An alternate version of a gene, e.g., Gregor Mendel's pea plants have flowers with two colors: white and reddish-purple. Adenoviruses infect membranes of the respiratory tract, eyes, intestines, and urinary tract, and can cause respiratory infections and gastrointestinal upsets.Ģ4 Animation, 24 Bio agarose gel electophoresis A matrix composed of a highly purifiedįorm of agar is used to separate larger DNA and RNA molecules rangingĢ3 Animation 24 Animation, 24 Video, 24 Bio 29 Animation alkaptonuria A rare inherited condition in which a person's urine turns a dark brownish-black color when exposed to air. Abbreviated with an 'A.'ġ5 Animation 19 Animation 20 Animation 21 Animation 22 Animation 23 Animation, 23 Problem 26 Animation 28 Animation adenovirus Adenoviruses contain double-stranded DNA and are unusually stable, allowing them to survive for prolonged periods outside of the body. Talking Glossary of Genetic Terms from National Human Genome Research Institute.Ī Activator ( Ac) An autonomous transposable element in maize that also controls the movement of another transposon, Dissociator ( DS).ģ2 Animation, 32 Video adenine One of the four bases that make up DNA. ![]()
