KARYOTYPING What do your chromosomes look like?
Karyotype Cell treated with chemical to stop in metaphase Chromosomes stained Picture taken Enlarged Cut out Matched by banding patterns Arranged by size and location of centromere

What can you tell from a Karyotype?
From a Karyotype You can tell –Correct number of chromosomes –Correct size and shape of chromosomes –Gender
Female with Trisomy 21 Down Syndrome
Male with Trisomy 21 Down Syndrome
Deletion of Long Arm Chromosome 4
Extra X – Klinefelter’s Syndrome
Missing X – Turner’s Syndrome
SKY – Spectral Karyotypes Uses fluorescent “tags” specific to each chromosome

Genetic Changes Any mistake or change in the DNA sequence is called a mutation. Types of mutations are: point mutation frameshift mutation chromosomal.

Karyotypes & Genetic Disorders
CHROMOSOMES & CELL DIVISION TOPIC CHROMOSOMES & CELL DIVISION Things to cover Chromosomes Karyotypes ◦ inc. chromosomal disorders Cell division:
KARYOTYPING. 1.What is this? 2.How many chromosomes are in a human body cell? 3.How many pairs are in a human cell? 4.Which chromosomes determine gender.
Karyotypes and Karyotyping

KARYOTYPE TESTS. KARYOTYPE = Image of all the chromosomes from the nucleus of a cell Can be done to identify genetic disorders.
Karyotypes. I. What is a Karyotype? Karyotype = a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells.
Investigating Chromosomal Abnormalities
Chromosomes and Karyotypes Chromosomes are comprised of a single, uninterrupted DNA molecule and proteins (histones) A karyotype is a visual display of.

Karyotypes. Karyotypes are pictures of homologous chromosomes lined up together during metaphase I of meiosis. There are 44 autosomes and 2 sex chromosomes.
Journal: Where is DNA found inside a cell?. Usually DNA inside the nucleus is wrapped around proteins to form an ‘X’ shape These ‘X’ shaped coils.
Genes and Chromosomes. Gene Segment of DNA whose sequence codes for a specific product – Examples: physical trait, RNA, enzymes etc. Genes are located.
KARYOTYPING Honors Biology. What and How? Used as a way to “see” the chromosomes Pairs up homologous chromosomes Allows for detection of several genetic.
A Chromosome Study Please pick up 1 set of chromosomes marked “normal” and 1 set of abnormal chromosomes labeled A B C or D, in addition to the lab handout.
