set | Questions with verified Answers
Difficult form of DNA to move? - ANSW-Chromatin
Easy form of DNA to move? - ANSW-Chromosome
Easily replicated form of DNA? - ANSW-Chromatin
Difficult replicated form of DNA? - ANSW-Chromosome
Easy to see under a microscope? - ANSW-Chromosome
Difficult to see under a microscope? - ANSW-Chromatin
Where is DNA found? - ANSW-nucleus
What does DNA store? - ANSW-Genetic information
How is DNA passed down? - ANSW-from parent to offspring
DNA stands for? - ANSW-deoxyribonucleic acid
What is cell division used for? - ANSW-make more cells and pass on their DNA
What is the division of somatic cells? - ANSW-mitosis
What is the division of germ cells? - ANSW-meiosis
What is the basis for meiosis? - ANSW-genetic variation
Human gametes - ANSW-sperm and egg
plant gametes - ANSW-pollen and ovules
What does meiosis create? - ANSW-genetic diversity
What does diploid mean? - ANSW-2 copies of each chromosome
What type of cell are human somatic cells? - ANSW-diploid
What does haploid mean? - ANSW-1 copy of each chromosome
What type of cell are human gametes? - ANSW-haploid
How do you identify and count chromosomes? - ANSW-Centromeres
What is meiosis essential for? - ANSW-Sexual reproduction and continuation of a species
What is evolution? - ANSW-The gradual change in a species over time
Genetic diversity - ANSW-differences between organisms of the same species
What 3 processes create genetic diversity? - ANSW-crossing over, independent assortment, and
segregation
When does crossing over occur? - ANSW-late prophase 1
When does independent assortment occur? - ANSW-Prophase 1- anaphase 1
When does segregation occur? - ANSW-Anaphase I
Why can't these processes (crossing over/i.a./segregation) occur during meiosis 2? - ANSW-There are no
homologous pairs
# of chromosomes and chromatids in Pre-S interphase - ANSW-6;1
# of chromosomes and chromatids in Post-S interphase - ANSW-6;2
