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...
Which of the following structures would not be found in a prokaryotic cell? a. cell membrane b. nucleus c. chromosomes d. ribosomes e. flagella Which of the following cellular components does both prokaryotes and eukaryotes have? Select all that app...
Prokaryotes do not do mitosis because of their simple cellular structure. Prokaryotes lack the chromosomes that are in eukaryotes and instead have a... Learn more about this topic: Binary Fission | Definition, Steps & Examples from Chapter 5/ Lesson 2 ...
In most eukaryotes, pairing of homologous chromosomes is an essential feature of meiosis that ensures homologous recom- bination and segregation. However, when the pairing process begins, it is still under investigation. Contrasting data exists in Mus musculus, since both leptotene DSB-dependent and ...
Some time later, the early eukaryotes developed sexual reproduction where genetic material is shared between two individual members of the species in order to reproduce as opposed to earlierbinary fission. Reasons whyare debated, but my preferred explanation is that sexual reproduction increases the pro...
All eukaryotes have … 1) A Cell membrane 2) A Central nucleus 3) Organelles in cytoplasm (like ER, vacuoles, mitochondria, etc.) Theories of the Origin or organelles Symbiosis: two organisms live closely together Endosymbiosis: one organism lives inside another (bacteria in us) ...
A nucleosome is typically a fundamental structural unit of DNA packaging, which essentially occur in eukaryotes. The structure of a typical nucleosome... Learn more about this topic: Chromosome Structure, Composition & Location from Chapter 8/ Lesson 2 ...
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 cells also have ribosomes. In prokaryotes, these float freely in the cytoplasm; in eukaryotes they are typically bound to the endoplasmic reticulum. Ribosomes are often classified as a type of organelle, but in some schemes they do not qualify as such because they lack a membrane. Not ...
