The nucleiod region
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
gene is a specific region of chromosome
Genes are the regions of DNA within a chromosome that encode specific instructions for making proteins or functional RNA molecules. These genes are the basic units of heredity and are responsible for determining an organism's traits and characteristics.
No, prokaryotic genes do not have introns.
A gene is a specific region of DNA that codes for a particular protein. A chromosome is a long, continuous thread of DNA that consists of numerous genes and regularity information
Prokaryotes have a single circular chromosome located in the nucleoid region, whereas eukaryotes have multiple linear chromosomes located in the nucleus. Prokaryotic chromosomes are smaller in size and contain fewer genes compared to eukaryotic chromosomes which are larger and more complex. Eukaryotic chromosomes are associated with proteins to form chromatin, while prokaryotic chromosomes do not have associated proteins.
Yes, linked genes are genes located on the same chromosome.
The region of chromosome that is generally thought of as the unit of function is the "gene". Genes are composed of both a "coding region"--that sequence that tells the cell's machinery what the protein will be--and a "regulatory" region, which tells the cell when to turn on the coding region to make the protein.
Genes that are located on the same chromosome are called linked genes. These genes tend to be inherited together during cell division because they are physically close to each other on the same chromosome.
Most prokaryotic genomes are small (<~5Mb), they generally contain one large circular piece of DNA refered to as a "chromosome" (not a true chromosome in the eukaryotic sense so inverted comas are normally used in modern text). Some bacteria have linear "chromosomes". Many bacteria extra DNA hald on small circular structures called plasmids which can be swapped between neighbours and across bacterial species. Inside the "choromosome" many genes with related functions are found close together in operons. The exact order and number of genes found in the genome can vary between different strains of the same species. Prokaryotes can gain genes from other prokaryotic species when sharing an environment. The DNA is gene rich with a few non-coding regions containing insertion elements or transposons. There are no introns in prokaryotic genes. There are very few repeated sequences in prokaryotic genomes. Eukaryotic genomes are generally larger (#10Mb -100,000Mb) than prokaryotic ones. Their DNA is held on linear chromosomes and a small circular mitochondrial chromosome. Genes have introns. There are many genome wide repeats. There are longer space between genes and a great number of non-coding sequences. The number of genes doesn't normally differ between strains of a species.
Yes, linked genes are located on the same chromosome.
No, a gene is a specific region of DNA that contains the instructions for making a particular protein or RNA molecule. A chromosome is a long strand of DNA that can contain many genes as well as other genetic material. Each chromosome may contain hundreds or thousands of genes.
