Are There Chromosomes In The Stages Of Cell Cycle? In mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules. Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase. How
What Are Homologous Chromosomes Easy Definition? 1. A pair of chromosomes made up of two homologs. Homologous chromosomes have corresponding DNA sequences and come from separate parents; one homolog comes from the mother and the other comes from the father. Homologous chromosomes line up and synapse during meiosis. 2. What is a simple definition of
Does Repair By Homologous Recombination Change Dna Length? Homologous recombination (HR) is a DNA metabolic process found in all forms of life that provides high-fidelity, template-dependent repair or tolerance of complex DNA damages including DNA gaps, DNA double-stranded breaks (DSBs), and DNA interstrand crosslinks (ICLs). What type of damage does homologous recombination repair? 1.1 DNA
Does Repair By Nonhomologous End Joining Change Dna Length? Our results suggest that NHEJ is a faster and more efficient DSB repair pathway than HR. Why do cells use non-homologous end joining? Nonhomologous end-joining is another DNA repair mechanism that resolves DSBs. Since it relies on no sequence homology or short overhangs at DSBs, it
Does Each Chromosome Have The Same DNA? Does each chromosome have the same DNA? Different chromosomes contain different genes. That is, each chromosome contains a specific chunk of the genome. For example, in humans the gene for alpha globin, a part of the hemoglobin protein that carries oxygen in red blood cells, is found on
How Many Phases Are There In The Cell Cycle? In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the
