Bicd 100 Genetics - Normal Chromosome Behavior

Front 1

Acrocentric

Back 1

centromere near the end of the chromosome
very short arm and long arm

Hint 1

Hint 1. One of three types of chormosomes
Hint 2. Based on the position of the centromere

Front 2

Anaphase

Back 2

Fourth Stage of Mitosis
Chromosomes are pulled apart into individual chromatids

Hint 2

Fourth Stage of Mitosis

Front 3

Autosome

Back 3

Chromosomes which are the same in both sexes (same in number as well as type)

Hint 3

Type of Chromosome

Front 4

Autosomal

Back 4

Relating to Autosomes

Front 5

Banding pattern

Back 5

Pattern which uniquely identifies a chromosome

Hint 5

The same from chromosome homologs

Front 6

Centromere

Back 6

The regsion where the four arms of the chromosome connect

Hint 6

Part of the Chromosome

Front 7

Chiasma

Back 7

A crossing in a homologous pair of chromosomes during Meiosis I.
At a Chiasma, chromosomes trade segments.

Hint 7

Occurs during Meiosis I

Front 8

Chomatid

Back 8

One of the two visibly distinct longitudinal subunits of all replicated chrromosomes that becomes visible between early prophase and metaphase of mitosis.

Hint 8

Part of a chromosome

Front 9

Chromatid disjunction

Back 9

The separation of sister chromatids at anaphase II

Front 10

Chromosome

Back 10

The genetic material of a cell
It literally means "colored body," because the threadlike structures are visible under the microscope only after they are stained with dyes.

Front 11

Chromosome disjunction

Back 11

The separation of homologous chromosomes at anaphase I

Hint 11

Underlies Mendel's observation of the segragation of alleles.

Front 12

Crossing over

Back 12

Synonym for Chiasmata
Region where chromosomes cross and exchange segments in Meiosis Prophase I

Hint 12

Synonym for Chiasmata

Front 13

Cytokinesis

Back 13

Divsion of cytoplasm which causes one cell to split into two cells.

Front 14

Dichtyotene

Back 14

Female Egg Prophase II stage of Meiosis. Egg (primary and secondary oocyte) stays hear until ovulation.

Hint 14

Relates to Female Mammal Meiosis

Front 15

Diploid

Back 15

Cells that have chromsomes in pairs

Front 16

Exchange

Back 16

Homologous Chromosomes physically exchange parts during Meiosis I

Hint 16

Occurs during Meiosis I

Front 17

first meiotic division

Back 17

Meiosis I - Separates Homologous chormosomes

Front 18

G1

Back 18

First part of interphase immediately following cellular division. During G1 chromosomes remain in the single chromatid condition.

Hint 18

Part of Interphase part of Mitosis cycle.

Front 19

G2

Back 19

Last part of Interphase. Chromosomes are in the two chormatid form.

Hint 19

Section of Interphase part of Mitosis cycle.

Front 20

Haploid

Back 20

Cells which contain only one copy of each chromosome.

Hint 20

Number of chromosomes...

Front 21

Homologs

Back 21

Chromsomes which containing the same genes (not the same alles but each locus controls the same trait)
