Is dna in a chromosome
WebBacterial chromosome. The double-stranded DNA of the circular bacteria chromosome is opened at the origin of replication, forming a replication bubble. Each end of the bubble is a replication fork, a Y-shaped junction where double-stranded DNA is separated into two single strands. New DNA complementary to each single strand is synthesized at ... WebIn addition to the chromosome, many prokaryotes have plasmids, which are small rings of double-stranded extra-chromosomal ("outside the chromosome") DNA. Plasmids carry a small number of non-essential genes and are copied independently of …

WebChromosomes, DNA, genes, and genomes are not all the same thing. Sometimes these words are used interchangeably, but they are not the same. DNA is the building block of the genetic material found in all living things. A very long chain of DNA can form a chromosome. In these chromosomes are areas called genes that code for specific proteins.
WebYou are correct that in humans--and, indeed, in most organisms: plants, animals, even bacteria--the genetic material is DNA. However, though we use DNA as our genetic material, we also do make use of RNA for other purposes, such as protein synthesis. RNA and mRNA are exactly the same thing. So is tRNA.
