Prokaryo c chromosomes are not contained in a membrane-bound nucleus. t/f -correct
answersTrue
at the end of DNA replica on, a duplicated chromosome consists of 4 iden cal DNA double
helices. t/f -correct answersFalse; 2 not 4
Homologous chromosomes are usually not iden cal. t/f -correct answersTrue
Gametes have exactly half the gene c informa on of their parent cells and reestablish the full
gene c complement when they fuse. t/f -correct answersTrue
Many plants and fungi reproduce both asexually and sexually. t/f -correct answersTrue
The prokaryo c cell cycle consists of rela vely short period of growth followed by mitosis. t/f -
correct answersFalse; Long periods of growth
Each chromosome has 1 telomere and 2 centromeres. t/f -correct answersFalse; 2 telomere 1
centromere
When looking at a karyotype, we see that most cells contain individual chromosomes. t/f -
correct answersFalse; pairs of chromosomes
, Each chromosome in a pair carries the same genes arranged in the same order. t/f -correct
answersTrue
Loose -> ght -correct answersDouble helix
Histones
Nucleosome
Chroma n
Chromosomes
3 categories of cells -correct answersStem cells
Permanently differen ated cells
other cells capable of dividing
1. The single prokaryo c chromosome is usually a ached to the plasma membrane of the cell
2. chromosomes replicates, produces 2 iden cal copies, that a ach to plasma membrane at
nearby, but separate sites
3. As the cell increases in size, new plasma membrane is added, pushing chromosomes apart
4. The plasma membrane grows inward between the two chromosome copies
5. The parent cell divides into two daughter cells, with each one gene cally iden cal to the
parent cell and containing a single, circular chromosome -correct answers5 dis nct stages in the
prokaryo c cell cycle
What are the two types of chromosomes -correct answersHaploid and diploid
Eukaryo c chromosomes usually occur in pairs with similar gene c informa on. Do these pairs
have the same genes? If yes, are they in the same order? -correct answersThey carry the same
genes, in the same order
