Karyotyping - Study guides, Class notes & Summaries

karyotyping - number and type of chromosome present Barr body - -condensed inactive X chromosome near nucleus of cell -all females have 1 Barr body nondisjunction - failure of chromosomes to separate during meiosis autosomal nondisjunction - -failure of chromosomes (other than sex chromosomes) to separate during meiosis -exs: trisomy 21, trisomy 18 translocation - portion of one chromosome is transferred to another (usually nonhomologous) abnormal egg (XX) x normal sperm (X) - -zygote: X...

Plasmid DNA purification steps 1. grow the bacteria with the plasmid 2. centrifuge 3. remove supernatant 4. resuspend pellet in lysis buffer (detergents and high salt) 5. neutralize the lysis buffer 6. spin down to remove debris and genomic DNA 7. put the suspension on a spin column 8. plasmid DNA will adhere to spin column and everything else will be washed away with high salt buffers 9. add low salt buffer to remove plasmid DNA from spin column RNA purification steps Same s...

Gizmo Simulation: Human Karyotyping questions and answers 2023 Why do you think humans have two sets of 23 chromosomes? Humans have two sets of 23 chromosomes because you get a set from your mother and the other set from your father, resulting in two sets. What aspects of the genome can and cannot be determined through karyotyping? Karyotyping can give information on an individual's sex and on chromosomal disorders. Karyotyping does not give any information on the specific traits enco...

Gametes Sex cells 2. Karyotype A display of the chromosome pairs of a cell arranged by size and shape. 3. Process for karyotyping Typically done by isolating white blood cells from a person, staining them, and taking pictures under a microscope. The picture is then cut to organize chromosomes, which are numbered by size 4. Cytogeneticist a scientist who studies chromosomes under the microscope 5. BRCA1 gene Breast cancer type 1 susceptibility gene. A human tumor suppressor gene that is...
