The structure of a nucleus encompasses the nuclear membrane, nucleoplasm, chromosomes, and nucleolus. Nuclear Membrane The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. The outer layer of the membrane is connected to the endoplasmic reticulum. Like the cel...
The cytological observations pose a dilemma which remains to be resolved, since the pattern of distribution of labeled DNA into daughter chromosomes is not that expected for semi-conservative replication of DNA in a bineme chromosome (Schwartz, 1958). In contrast to the observed result that ...
The so-called “mitotic clock” counts the number of cell divisions that have occurred and pushes the cell to apoptosis before a critical telomeric shortening is reached. If this should occur, chromosomes would be prone to fuse end to end, giving rise to sticky ends that would favor mitotic ...
The nucleus contains the cells’ genetic information known as Deoxyribonucleic Acid (DNA), on the Chromosomes (special thread-like strands of nucleic acids and protein found in the nucleus, carrying genetic information). Nucleus Diagram Structure of the nucleus of the plant cell ...

18 S, 5.8 S, and 28 S rRNAs are the transcription products of closely linked genes in the chromosomes of the nucleolar organizing region (NOR) of the cell nucleus. Considerable redundancy exists as hundreds, perhaps even thousands, of copies of these rRNA genes are believed to be pre...
Microtubules not attached to chromosomes elongate and push apart, separating the poles and making the cell longer. What is anaphase with diagram? During anaphase, the chromosomes that are lined up in the center of the cell are pulled apart, separating the sister chromatids. The chromatids are ...
Angiosperms have two distinct stages of life. One is the haploid stage, where cells produced have one set of chromosomes and is the sexual stage of life. The other is the diploid stage, where cells produced have two sets of chromosomes and in which the plant spends the majority of its lif...
