a type of reproduction-fission, budding and regeneration-in which a new organism is produced from one organism and hasDNA identical to the parent organism.
structures in the cell nucleus that contain hereditary material
cell whose similar chromosomes occur in pairs
deoxyribonucleic acid; the genetic material of all organisms; made up of two twisted strands of sugar-phosphate molecules and nitrogen bases
haploid sex cell formed in the female reproductive organs
in sexual reproduction, the joining of a sperm and egg
section of DNA on a chromosome that contains instructions for making specific proteins
cell that has half the number of chromosomes as body cells
reproductive process that produces four haploid sex cells from one diploid cell and ensures offspring will have the same number of chromosomes as the parent organisms.
cell process in which the nucleus divides to form two nuclei identical to each other and identical to the original nucleus, in a series of steps(prophase, metaphase, anaphase and telophase)
any permanent change in a gene or chromosome of a cell; may be beneficial, harmful, or have little effect on an organism
ribonucleic acid; a type of nucleic acid that carries codes for making proteins from the nucleus to the ribosomes
A type of reproduction in which two sex cells, usually an egg and a sperm, join to form a zygote, which will develop into a new organism with a unique identity.
haploid sex cell formed in the male reproductive organs; in humans, male reproductive cells produced in the testes
New diploid cell formed when a sperm fertilizes an egg; will divide by mitosis and develop into a new organism.
