During which phase of the cell cycle does DNA replication occur? a. Prophase b. Interphase c. Cytokinesis d. G1 phase Cell Cycle: The cell cycle is the phase in which a cell goes through during its lifespan. The cell cycle is composed of...
When does replication of DNA occur in the formation of gametes? a. Early prophase I. b. Mid-Prophase I. c. Early Prophase II. d. Mid-Prophase II. e. Metaphase I. The stage in a cell's life cycle in which the cell performs its normal functions and prepares for cell division is cal...
A. Interphase B. Prophase C. Metaphase D. Anaphase 相关知识点: 试题来源: 解析 A。细胞周期中,间期负责 DNA 复制。间期包括 G1 期、S 期和 G2 期,其中 S 期进行 DNA 复制。前期(B 选项)主要是染色体出现等变化。中期(C 选项)染色体排列在赤道板上。后期(D 选项)姐妹染色单体分离。
DNA and certain proteins known as histones form the chromosomal structures. The DNA is double-stranded and forms a tightly coiled package with the assistance of the histones. During interphase, the chromosomes relax, giving replication enzymes access to create a new copy of each chromosome. The tw...
As hereinabove stated, the prokaryote is transformed with DNA which includes at least one DNA sequence which encodes immunity to a lytic bacteriophage. Temperate bacteriophages can adopt two different life cycles. The lytic cycle involves simple reproduction of viral particles within a bacterial cell,...

The 3′-end bias does not occur when random primers are used for the cDNA synthesis. Random primers do not require a poly-A tail since they can attach to any region of the mRNA and not only to its 3′-end, promoting synthesis in a 3′ ➔ 5′ direction, and a very strong 5′...
cells stall in G0/G1 phase and undergo senescence. Cell cycle blockage and senescence activation prevent activation of the repair machinery. These cells did not exhibit mortality in the first 3–4 days, but a complete mortality followed 1–2 weeks after treatment. The image was created with Bi...
