Bio chapter 8

Crossing over is important because it

Creates genetic variation

In bacterial cells, binary fission involves

Distribution of a copy of the single parental chromosome to each daughter cell

Cytokinesis refers to

Division of the cell outside nuclear material

The diploid phase of the human life cycle begins with

Fertilization

During asexual reproduction, yeast cells can produce

Genetically identical offspring

Chromatids are

Identical copies of each other if they are part of the same chromosome

Centrosomes begin to move apart to opposite poles of the cell

In prophase

In some organisms such as certain fungi and algae, cells undergo mitosis repeatedly without subsequently undergoing cytokinesis. What could be the consequence of this?

Large cells containing many nuclei

AFTER fertilization, the resulting zygote begins to divide by

Mitosis

Centrosomes____ during cell division

Organize the microtubules

The term binary fission is best applied to

Prokaryotes

Chromatin coils in

Prophase

Motorola spindle begins to form

Prophase

Crossing over occurs in

Prophase 1

An exchange of parts between non homologous chromosomes is called

Reciprocal translocation

Chromatids form during the

S phase

Anaphase and telophase

Single sister chromatids are found

Kinetic horse are

Sites at which microtubules attach to chromosomes

DNA replication occurs in

The S phase of interphase

The phase of mitosis where chromosomes move towards separate poles of the cell

Anaphase

What is the difference between benign and malignant tumors

Benign do not metastasize while malignant do.

What occurs during mitosis

Chromatids separate
