Prokaryotes vs Eukaryotes
This region contains DNA in prokaryotic cells.
What is the nucleoid?
DNA wraps around these proteins to form nucleosomes.
What are histones?
Interphase consists of these three phases.
What are G1, S, and G2?
Chromosomes line up at the metaphase plate during this phase.
What is metaphase?
A segment of DNA that codes for a protein.
What is a gene?
Prokaryotic genomes consist of this type of DNA molecule.
What is a single circular chromosome?
The “beads on a string” structure is called this.
What is nucleosomes?
DNA replication occurs during this phase.
What is S phase?
Sister chromatids separate during this phase.
What is anaphase?
Different versions of the same gene.
What are alleles?
Small extra DNA loops in bacteria that often carry antibiotic resistance genes.
What are plasmids?
This level of compaction forms a 30 nm fiber.
What is the chromatin fiber?
Cell growth and normal function primarily occur in this phase.
What is G1?
The nuclear envelope reforms during this phase.
What is telophase?
Two identical copies of a replicated chromosome.
Two identical copies of a replicated chromosome.
The number of chromosomes in human somatic cells.
What is 46 (2n, diploid)?
Each chromosome occupies its own ______ in the nucleus.
What is a region?
This structure duplicates during S phase to prepare for mitosis.
What is the centrosome?
Spindle fibers attach to chromosomes at this structure.
What is the kinetochore?
Division of the nucleus is called this.
What is mitosis (karyokinesis)?
These chromosomes are similar in length and gene location and come from different parents.
What are homologous chromosomes?
Approximately how long is DNA from all 46 chromosomes in one human cell if stretched out?
What is about 2 meters?
The final check before entering mitosis occurs during this phase.
What is G2?
The correct order of mitosis phases.
What is Prophase → Prometaphase → Metaphase → Anaphase → Telophase?
Division of the cytoplasm is called this.
What is cytokinesis?
