Explore the cell cycle and cellular division in eukaryotic cells, leading to the creation of identical daughter cells, and contrast it with prokaryotic binary fission. Understand Mendelian inheritance and the genetic variation it explains, along with the structure and function of DNA. Delve into gene expression and its regulation, and how developmental biology and evolution shape life.

During interphase, the cell grows and replicates its DNA
Mitosis
Mitosis is the process of dividing duplicated chromosomes into two new nuclei
Cytokinesis
Cytokinesis is the process of dividing the cytoplasm, completing cell division
Meiosis I
Meiosis I is the first division in the process of creating four non-identical haploid cells
Meiosis II
Meiosis II is the second division in the process of creating four non-identical haploid cells
Binary fission is the process of prokaryotic cell division, resulting in two genetically identical daughter cells
The protein FtsZ plays a critical role in forming a septum during prokaryotic cell division
Law of Segregation
The law of segregation states that allele pairs separate during gamete formation
Law of Independent Assortment
The law of independent assortment states that genes for different traits are distributed to gametes independently
Genetic linkage can affect the law of independent assortment by causing genes located close together on the same chromosome to be inherited together
DNA is a double helix composed of two strands of nucleotides, with each strand containing a sugar-phosphate backbone and nitrogenous bases
DNA replication is a semiconservative process, resulting in two new DNA molecules each consisting of one original and one new strand
Mutations in the DNA sequence can lead to changes in an organism's genotype and potentially its phenotype
Transcription
Transcription is the process of copying DNA into mRNA
Translation
Translation is the process of using mRNA to assemble amino acids into a protein
Gene regulation is critical for cell function and differentiation and can occur at multiple levels, from DNA accessibility to post-translational modifications of proteins
Developmental biology studies how organisms grow and develop from a single cell into a complex structure
Natural Selection
Natural selection favors individuals with traits that improve survival and reproductive success
Speciation
Speciation is the process by which new species emerge over time
Phylogenetics is the study of the evolutionary relationships among species, providing insights into the history of life on Earth
00
Stages of Mitosis
Prophase, metaphase, anaphase, telophase; chromosome segregation.
01
Cytokinesis Function
Divides cytoplasm, completes cell division.
02
Meiosis Genetic Diversity Mechanisms
Crossing over, independent assortment; creates unique haploid cells.
