The study of life

Form of nuclear division that divides a diploid cell into haploid cells; important in forming gametes for sexual reproduction

The cell copies its DNA and grows in preparation for division. The DNA is loosely organized during interphase

The study of heredity patterns and variation of organisms

All scientific discoveries begin with a

The smallest unit of life

The process by which a cell divides its nucleus and contents

DNA and Proteins condense into tightly coiled chromosomes. The nuclear envelope breaks down, centrioles begin to move to opposite poles, and spindle fibers form

A unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

When scientist want to test a certain observation they create what is known as a

Study of the interactions among living things and their surroundings

produces 2 new cells that are exactly like the original cell

Spindle fibers attach to each chromosome. They align the chromosomes along the cell equator

The allele that is expressed when two different alleles are present on a chromosome

Scientist gather _______ to support or contradict their hypothesis

Number of individuals that the resources of an environment can normally and persistently support

Produces 4 new cells with half of the DNA from the original cell

Chromatids separate to opposite sides of the cell. Cytokinesis usually begins in the late anaphase or telophase

The allele that is expressed when two copies are present on the allele

Essentially, in science, nothing is definite, things are always changing. Science relies on ________ instead of absolute truths

Long, continuous thread of DNA that consists of numerous genes and regulatory information

There are 6 phases of this cell division

Nuclear membranes start to form, chromosomes begin to uncoil, and the spindles fibers fall apart

Two chromosomes-one inherited from the mother, one from the father- that have the same length and general appearance

A formal way for scientists to get feedback to get feed back is by having their work
