DNA vocabulary Flashcards
chromosomes
in a Eukaryota cell, one of the structures in the nucleus that are made up of DNA and proteins; in a Eukaryota cell the main ring is DNA.
chromatid
one of the two strands of a chromosome that becomes visible during mitosis and meiosis
chromatin
the material that makes up path mitosis and interphase chromosomes;a complex of proteins and DNA strands that are loosely celled such that translation and transcript can occur
cell plate
the precursor of a new plant cell wall that forms during cell division a cell into two.
exon
in a struggle, of one f the segment that are ultimately transcribed and translated when the gene is expressed
haploid
describes a cell , nucleus,or organism that has only one set of unpaired chromosomes
mitosis
in Eukaryota cells, a process of cells division that forms two new nuclei, each of which has the same number of the chromosomes.
spindle fiber
form a protein structure that divides the genetic material in cells
diploid
containing sets of chromosomes, one from each parent
intron
a segment of a DNA or RNA molecules that does not code for proteins and interrupt the sequence of gene.
centromere
the region of a chromosome to which the micro tubes of the spindle attached via the kinotochore dividing cell division
meiosis
a type of cell division that results in the four daughter cells each with half the number of chromosomes o the pant cell, as in the production of genetic and plant pores
karyotyple
the number and visual appearance of the chromosomes in the cell nucleus of an organism or species
gamete
a mature haploid male or female germ cells that is able to unit with another of the opposite sex in sexual reproduction to form a zygote
