Cell Divison

List the stages of mitosis in order: prophase, metaphase, anaphase, telophase
How many daughter cells are produced from one cell after mitosis? 2
Which phases of the cell cycle are represented by growth, carrying out cell function and preparing for the cell to divide. G1 - phase where the cell grows and carries out its function G2 - phase where the cell prepares to divide
What happens during the S phase of interphase? DNA copies as the cell prepares to divide
If there are 46 chromosomes in a human skin cell, how many chromosomes are in a human sperm cell? 23
When a chromosome copies itself, it is held together by a.....? centromere
The two identical chromosomes held together by the centromere are called sister ______? chromatids
In this stage of mitosis, the chromosomes line up in the middle of the cell. metaphase
In this stage of mitosis, the sister chromatids can be seen and a spindle begins to form. prophase
In this stage of cell division, the cytoplasm divides cytokinesis
In this stage of mitosis, the sister chromatids begin to separate and move to opposite ends of the cell anaphase
The period where the cell grows, copies its DNA, makes proteins interphase
A highly regulated system of signals that controls normal cell divison cell cycle
The X and Y chromosomes are called _____ chromosomes sex
Gametes (sperm and egg) that have half the number of chromosomes are called ______________ haploid
Before a cell can divide, what must happen to the DNA must be copied (during the S phase of interphase)
Somatic cells (body cells) undergo ___________ (type of cell division) mitosis
Sex cells (gametes) undergo _____________ (type of cell division) meiosis
The longest phase of the cell cycle is interphase
Why do cells need to undergo cell division? So organisms can grow, and repair tissue
If a somatic cell has 20 chromosomes and undergoes cell division (mitosis), how many chromosomes will each new cell have after cell division 20 because mitosis gives us identical daughter cells
