Simplified version that an intro Biology course would look for:
Eukaryotes have multiple pairs of linear chromosomes. The gene-coding sequences are interspersed with non-coding regions that may control gene regulation. Within a gene sequence, there are exons (coding regions) and introns (non-coding regions that will be removed from the mRNA). Prokaryotic chromosomes are tightly wrapped around proteins called histones. Eukaryotic chromosomes are contained in a nucleus.
Prokaryotes have 1 circular chromosome, and may have smaller extrachromasomal DNA in the form of plasmids. Prokaryotic DNA does not have the non-coding regions or introns. Bacteria do not have histones, but archaea have histone-like structures associated with their chromosomes. Prokaryotic chromosomes exist in the cytoplasm.
Reality about Bacterial Chromosomes:
Although many have only the 1 circular chromosome, there are many exceptions to this rule Borrelia burgdoferi (corkscrew-shaped bacteria that causes Lyme Disease) has 17 linear chromosomes and many plasmids.
What else can I help you with?
Are homologous chromosomes present in prokaryotic cells?
No, homologous chromosomes are not present in prokaryotic cells. Prokaryotic cells have a single circular chromosome that is not organized into homologous pairs like in eukaryotic cells. Homologous chromosomes are found in eukaryotic cells and are pairs of chromosomes that contain similar genes.
How are human chromosomes 21 and 22 similar?
Chromosomes 21 and 22 are the smallest human autosomes. Chromosome 22 contains approximately 43 million DNA base pairs. Chromosome 21 contains roughly 32 million base pairs. These were the first two hu8man Chromosomes whose sequences were determined.
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
Which cytoplasmic organelles are treated as prokaryotic cells within the eukaryotic cells?
Mitochondria and chloroplasts are treated as prokaryotic cells within eukaryotic cells because they have their own DNA, divide independently of the cell, and have double membranes similar to those found in prokaryotic cells like bacteria. This has led to the theory of endosymbiosis, suggesting that these organelles were once free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells.
Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
Are homologous chromosomes present in prokaryotic cells?
No, homologous chromosomes are not present in prokaryotic cells. Prokaryotic cells have a single circular chromosome that is not organized into homologous pairs like in eukaryotic cells. Homologous chromosomes are found in eukaryotic cells and are pairs of chromosomes that contain similar genes.
Similarities and differences between prokaryotic and eukaryotic cells?
The similarities between prokaryotic and eukaryotic cells include that they both have vesicles and vacuoles. The differences between them include the fact that eukaryotic cells have a nucleus, mitochondria and a cytoskeleton whereas prokaryotic cells do not.
What are the similarities of prokaryotes and eukaryotes?
Prokaryotic and eukaryotic cells are similar in which of the following ways?
What eukaryotic organelle is functionally similar to the prokaryotic cell membrane and its infoldings?
Hup li
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
The presence of which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
The presence of mitochondria in eukaryotic cells indicates that they have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and are believed to have originated from a symbiotic relationship between an ancestral prokaryotic cell and an archaeon.
How are are binary fission and mitosis similar how are they different?
they are different because Binary is a prokaryotic cell and mitosis is a eukaryotic.
How are human chromosomes 21 and 22 similar?
Chromosomes 21 and 22 are the smallest human autosomes. Chromosome 22 contains approximately 43 million DNA base pairs. Chromosome 21 contains roughly 32 million base pairs. These were the first two hu8man Chromosomes whose sequences were determined.
Between which cell types is the difference greater-plant and animal cells or prokaryotic and eukaryote cells?
Although both have their differences, prokaryotic and eukaryotic cells have the greater difference. The only major differences between plant and animal cells is that plants have a vacuole, chloroplasts, and a cell wall, while animal cells do not. Plant cells produce their own food, while animal cells mist consume food to obtain energy. The difference between prokaryotic and eukaryotic cells is much larger. Prokaryotic cells lack a nucleus and all other organelles. They have only one circular chromosome, and a plasmid. Eukaryotic cells are much more complex.
