Sexual Reproduction
Some of these can reproduce both sexually and asexually
organisms
They worked out a model of DNA
Watson Crick
the combining of an egg and a sperm
fertilization
Phase where the new chromosomes reach the end of the spindle and begin to uncoil
telophase
a male gamete
sperm
A disease that results when hemoglobin is not formed properly
Sickle cell anemia
a cell in which the nucleus has two copies of each chromosome
diploid
The equal distribution of the parent cell's genes between the two new daughter cells
mitosis
a female gamete
egg
The process of forming two DNA molecules from one
replication
a haploid reproductive cell designed to transfer or receive chromosomes during sexual reproduction
gamete
Phase where the membrane around the nucleus disappears and the chromosomes begin to coil up
prophase
a cell in which the nucleus has just one copy of each chromosome
haploid
These are sections of DNA
genes
occurs when two organisms each give a complete copy of their genes to form a new organism
sexual reproduction
Phase where each pair of sister chromatids of one X-shaped chromosome separates into two L-shaped chromosomes
anaphase
the new cell that forms from the union of two gametes
zygote
The number of different kinds of nucleotides in DNA
four
Double cell division process that creates the cells needed for sexual reproduction
meiosis
Phase where a spindle of fibers forms in the cell
prophase
