Eukaryotes: Eukaryote refers to any cell or organism with a distinct nucleus. A nuclear membrane encircles the well-defined chromosomes that make up the nucleus of a eukaryotic cell (bodies containing the genetic material). A chromosome is a lengthy DNA molecule that contains part or all of an...
48K Comparative genomics is the study of gene sequencing in DNA, and comparing the structures and functions of genes between different species. Learn the differences between prokaryotes and eukaryotes in their DNA and chromosomes. Related to this QuestionAre...
Why do prokaryotes have only one type of RNA polymerase? What are the functions of ribosomal RNA? Chromosomes of eukaryotes consist of a. DNA only. b. DNA and RNA. c. DNA and proteins. d. RNA only. e. proteins, DNA, and RNA. ...
Archaea and Bacteria reproduce throughfission, a process where an individual cell reproduces its single chromosome and splits in two. Eukaryotes reproduce through mitosis, which includes additional steps for replicating and correctly dividing multiple chromosomes between two daughter cells. What Is Asexual...
The contrasting dose of sex chromosomes in males and females potentially introduces a large-scale imbalance in levels of gene expression between sexes, and between sex chromosomes and autosomes. In many organisms, dosage compensation has thus evolved to
All the children of a female thus have the same genome. In androgenesis (Verworn, 1891, Wilson, 1925), the development takes place only with the paternal chromosomes, after expulsion or destruction of the maternal chromosomes. Although rare, this phenomenon exists in nature in some animal ...
In eukaryotes (plants, fungi and animals), many of these ribosomes are attached to a "highway-like" membrane-heavy feature called theendoplasmic reticulum. This comes in two types, "smooth" and "rough." The cells of the liver, ovaries and testes have a high density ofsmooth endoplasmic ...
Pro> has no nucleus & have a single, circular chromosome located in a nucleoid. ; eukaryotes do have a nucleus surrounded by a complex nuclear membrane that contains multiple, rod-shaped chromosomes.Pro> Archaea and Bacteria; eukaryotic o...
How do the differences in genomes and reproduction increase the diversity of eukaryotes as compared to prokaryotes? How does recombination change the genetics of organisms? Bacteria would be an example of an organism that undergoes asexual reproduction. How would these org...
Abstract Stem cells are endowed with the awesome power of self-renewal and multi-lineage differentiation that allows them to be major contributors to tissue homeostasis. Owing to their longevity and self-renewal capacity, they are also faced with a higher risk of genomic damage compared to differen...
