In the cell cycle, the cell’s DNA is replicated in interphase, the phase that precedes mitosis. Mitosis alternates with interphase to make up the cell cycle in its entirety.In fact, a cellcannotbegin mitosis until interphase is successfully completed. So we’ve explained that mitosis is the ...

应该是 mitosis 吧?生物学名词 "有丝分裂, 间接核分裂"
One of the most important processes for all living organisms is mitosis. In this lesson, explore the meaning, stages, and purpose behind this...
One major difference between mitosis and meiosis that can contribute significantly to genetic diversity in offspring is referred to as "crossing over" or "chromosomal crossover." Crossing over occurs only in meiosis. Homologous chromosomes can physically "swap" chromosomal segments, thereby ensuring that...
What is mitosis, and what is its importance?The cell cycleThe cell cycle consists of 3 main parts: interphase, mitosis, and cytokinesis. Most cells exist in the early parts of interphase. If necessary, cells progress through interphase by replicating DNA and preparing to divide its cellular ...
The major purpose of mitosis is for growth and to replace worn out cells. What is the difference between meiosis 1 and meiosis 2? However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II ...
The purpose of mitosis is to make new cells and if cells did not undergo mitosis multicellular organisms would not be able to grow or repair the body... See full answer below.Mitosis is the process of cell division. One parent cell divides and creates two identical daug...
Saccharomyces cerevisiae is at the forefront of defining the major recombination mechanisms/models that repair targeted double-strand breaks during mitosis. Each of these models predicts specific molecular intermediates as well as genetic outcomes. Recent use of single-nucleotide polymorphisms to track the...
Metaphaseis the third of the five phases of biological cell division, or more specifically, the division of what is inside that cell's nucleus. In most instances, this division ismitosis, which is the means by which living cells duplicate their genetic material (DNA, or deoxyribonucleic acid,...
