Cell Vocab.

Front 1

gamete

Back 1

--a haploid REPRODUCTIVE CELL that unites with another haploid reproductive cell to form a ZYGOTE

Hint 1

is single but sounds like half; for sexual reproduction so only needs to supply half

Front 2

binary fission

Back 2

--a form of ASEXUAL REPRODUCTION in single celled organisms by which one cell DIVIDES into two cells of the same size

Front 3

gene

Back 3

--a SEGMENT OF DNA that is located in a chromosome and that codes for a specific hereditary trait

Hint 3

genes make up chromosomes

Front 4

chromosome

Back 4

--in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA

Front 5

chromatid

Back 5

--one of the two STRANDS OF A CHROMOSOME that becomes visible during meiosis or mitosis

Front 6

centromere

Back 6

--the region of the chromosome that HOLDS THE TWO SISTER CHROMATIDS TOGETHER during mitoses

Hint 6

central location

Front 7

homologous chromosome

Back 7

--chromosomes that have the SAME SEQUENCE OF GENES that have the same structure, and that pair during meiosis

Hint 7

homo=same
chromosomes have genes;
pairs

Front 8

haploid

Back 8

--describes a cell nucleus or organism that has only ONE SET OF UNPAIRED CHROMOSOMES

Front 9

diploid

Back 9

--a cell that contains TWO HAPLOID SETS of chromosomes

Hint 9

di, dip means two

Front 10

zygote

Back 10

--the cell that results from the fusion of gametes; FERTILIZED EGG

Front 11

autosome

Back 11

--any chromosome that is NOT A SEX CHROMOSOME

Hint 11

not X or little puny y

Front 12

karyotype

Back 12

--an array of the chromosomes found in an individuals cells at metaphase of mitosis and arranged in homologous pairs and in order of diminishing size; PICTURE

Hint 12

used to make familiar picture

Front 13

cancer

Back 13

--a tumor in which the cells begin DIVIDING AT AN UNCONTROLLED RATE and become invasive
