Chloroplast Chromosome

Science / Genetics / Chloroplast Chromosome: Circular dna found in the photosynthesizing organelle (chloroplast) of plants instead of the cell nucleus where most genetic material is located.

Premature Chromosome Condensation (PCC)

Science / Genetics / Premature Chromosome Condensation (PCC): A method of studying chromosomes in the interphase stage of the cell cycle. MORE

P1-Derived Artificial Chromosome (PAC)

Science / Genetics / P1-Derived Artificial Chromosome (PAC): One type of vector used to clone dna fragments (100- to 300-kb insert size: average, 150 kb) in escherichia coli cells. Based on bacteriophage (a virus) p1 genome. MORE

Isochromosome

Science / Genetics / Isochromosome: A metacentric chromosome produced during mitosis or meiosis when the centromere splits transversely instead of longitudinally: the arms of such chromosome are equal in length and genetically identical MORE
