Question 0

Benign tumor

Answer 0

Mass of abnormal cells that remains at the site of it’s origin

Question 1

Anaphase

Answer 1

The fourth stage of mitosis in which the chromatids of each chromosome have separated in the daughter chromosomes are moving to the poles of the cell

Question 3

Binary fission

Answer 3

A method of asexual reproduction by division and have been prokaryotes binary fission does not involve mitosis put in Seguso eukaryotes there that undergo binary Fujian mitosis is part of the process

Question 6

Cell cycle

Answer 6

An ordered sequence of events in the life of a cell, from its origin in the division of s parent cell until its own division into 2; the eukaryotic cell cycle is composed of interphase (including G1, S, and G2 sub phases) and M phase (including mitosis and cytokinesis)

Question 7

Chromosomes

Answer 7

A cellular structure caring genetic material found in the nuclear sub eukaryotes cells each chromosome consists of one very long DNA molecule and associated proteins

Question 8

Chromatin

Answer 8

The complex of DNA and proteins that makes up a eukaryotic chromosome when the cell is not dividing chromatin exist and it’s disbursed form as a master very long thin fibers that are not visible with the light microscope

Question 9

Centromere

Answer 9

The specialist region of the chromosome were two sister chromatids are most closely attached

Question 10

Cytokinesis

Answer 10

The division of the cytoplasm to form two separate daughter cells immediately after mitosis mitosis one or mitosis to

Question 11

Centrosome

Answer 11

Structure present in the cytoplasm of animal cells important during cell division functions as a makers to be a orders and center syndrome has two centrioles

Question 12

Cleavage

Answer 12

The process of cytokinesis in animal cells characterized by pinching of the plasma membrane

Question 13

G1 phase

Answer 13

The first gap or growth phase of the cell cycle consisting of the portion of interface before DNA synthesis begins

Question 14

G2 phase

Answer 14

The second app or growth phase of the cell cycle consisting of the portion of interphase after do you know synthesis occurs

Question 15

Gametes

Answer 15

A haploid reproductive cells such as an egg or sperm gave me twos you know drink socially production to reduce the diploid zygote

Question 16

G0 phase

Answer 16

A non-dividing stay occupied with so that I have left the cell cycle

Question 17

Growth factor

Answer 17

A protein that must be present in the extracellular environment for the growth of normal development of certain types of cells a local regulator that XO nearby supposed to stimulate so roller for ration in differentiation

Question 18

Interphase

Answer 18

The period in the soul cycle in the cell is not dividing during interfaceso you metabolic activity is high chromosomes and organelles are duplicated and so size may increase in her phase codes for 90% of the cell cycle

Question 19

Mitosis

Answer 19

The process of nuclear division in eukaryotic cells conventionally divided into five stages pro fees prometaphase metaphase anaphase until the face mitosis conserves chromosome number by relocating replicated chromosomes equally to each of the daughter nuclei

Question 20

Meiosis

Answer 20

A modified type of so the vision in situ reproducing organisms consisting of two rounds of cell division but only one round of DNA replication it resulted in souls with half the number of chromosomes as the original cell

Question 21

Metaphase

Answer 21

The third stage of mitosis in which the spindle is complete in the chromosomes attached to microtubules at the Connecticut wars are all aligned at the metaphase plate

Question 22

Metaphase plate

Answer 22

In imaginary plane midway between the two poles of the cell in metaphase on with those syndrome years of all duplicated chromosomes are located

Question 23

Malignant tumor

Answer 23

A cancerous tumor that is invasive enough to impair the functions of one or more organs

Question 24

Metastasis

Answer 24

The spread of cancer cells two locations distant from their original site

Question 25

Cell plate

Answer 25

A double membrane cross the midline of the dividing played so between which the noon so I’ll forms during cytokinesis

Question 26

Cyclin

Answer 26

I’m cellular protein that occurs in cyclical he flunks you waiting concentration and the plates and important role in regulating the cell cycle

Question 27

Cyclin-dependent kinases

Answer 27

The protein kinase that is active only one attached to a particular Cyclin

Question 28

Prophase

Answer 28

The first stage of mitosis in which the chromatin condenses the mitotic spindle begins to form in the nucleolus disappears but the nuclear’s remains intact

Question 29

Somatic cells

Answer 29

Any cell in multicellular organism except the sperm or egg

Question 30

S phase

Answer 30

The synthesis phase of the cell cycle the portion of them in there for you during which DNA is replicated

Question 31

Telophase

Answer 31

The fifth and final stage of mitosis in which daughter nuclei are formed and cytokinesis is typically begun

Question 32

Sister chromatids

Answer 32

Either of two copies of the duplicated chromosome attached to each other by proteins at the centromere and sometimes along the arms while joined two sister chromatids make up on chromosome chromatids are usually believe you separated during mitosis or meiosis to
