Flashcards in Lab 14:Mitosis and meiosis Deck (20):
_______ and _________ are the processes by which cells reproduce.
Mitosis reproduces the _______ and cytokinesis ________ the cytoplasm.
Four phases of mitosis
Prophase, metaphase, anaphase, telophase
The period of time between nuclear division.
Three phases og interphase
G1, S, and G2
During the _____ phase, the cell grows by replacing the cytoplasm and organelles.
During the ____ phase, the DNA is replicated so the chromosomes consist of two chromatids.
During the ____ phase, cell growth continues, proteins are synthesized, and the centrioles are replicated.
The uncoiled DNA in the nucleus when the cell is undergoing its normal activity. Its coils form the chromosomes.
The rod shaped structures of DNA present in the cell during cell division.
The two identical strands of DNA which form a chromosome after DNA replication. Separated into two different cells during mitosis.
The number of chromosomes found in eggs or sperm.It is one half the diploid number of chromosomes. 23 in humans
Having two haploid sets of homologous chromosomes. The normal number of chromosomes in body cells. Humans have 46.
Phase where chromosomes condense from chromatin and the cell membrane disappears.
Phase where chromosomes line up along the cell's equator.
Phase where sister chromatids on each chromosome separate, and begin to move towards the poles of the cells.
Phase where chromosomes reach the poles of the cell, begin to unwind, and then assume the form of chromatin.
Phase where the division of the cytoplasm is not part of mitosis, but it usually occurs at the same time. Here, the cells divides in half. Each half receives approximately half of the cytoplasm.
_________ separates the homologous chromosomes into two different cells.
