How is ribosomal DNA arranged on chromosomes? How is the nucleus involved in protein synthesis? How does DNA replication work? Does prokaryotes or archaea have a mitochondria? In microbiology, how does binary fission happen? How is bacterial DNA replication different from eukaryotic DNA replication?
Because the DNA of a fruit fly is understood very well, let's use the fruit fly as an example, specifically that of Drosophilia melanogaster. Here are some facts about fruit fly DNA: The DNA of a fruit fly is arranged on five chromosomes. There are about 250 million base pairs in this...
How is ribosomal DNA arranged on chromosomes? What is the difference between chromatin and a nucleosome? How is DNA stored in eukaryotic cells? How does DNA relate to epigenesis? How are DNA and mRNA alike? How is DNA packaged in the nucleus of somatic cells? How does the DNA of prokaryot...
The terms ‘eukaryote’ and ‘prokaryote’ were introduced Edouard Chatton in 1925 (Chatton, 1925, cited in Sapp, 2005). Eukaryotes, according to the online Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokary...
Proteins that work closely with one another in the cell often have their genes located on different chromosomes, and adjacent genes typically encode proteins that have little to do with each other in the cell. Decoding genomes is therefore no simple matter. Even with the aid of powerful ...
However, it is also thousands of timesthinnerthan a strand of hair. Locationally speaking, DNA is found inside the nucleus of each of the body’s cells, tightly packed into packages known as chromosomes. Packaging of DNA into the cell nucleus (Photo Credit : Designua/Shutterstock) ...
Embedded in these membranes are the nuclear pore complexes (NPCs) — large protein complexes that act as passageways for the transport of molecules into and out of the nucleus. The mammalian NPC is composed of multiple copies of 30 different proteins, called nucleoporins (Nups), arranged in ...
All genes are made up of stretches of these four bases (arranged in different ways and in different lengths). You can view a 3-D rotatable image of DNAhere... Photo: National Institute of Health A critical feature of DNA is the ability of the nucleotides to make specific pairs: . Adeni...
situ hybridization (FISH) with 18S rDNA and telomeric probes FISH is a technique that uses fluorescent probes binding selectively the chromosome parts with a high degree of sequence complementarity, thus detecting and localiz- ing the presence or absence of specific DNA sequences on chromosomes...
Class:DNA Sequence Alignment File The LAV file extension is a data file type, the LAV file is created by LASTZ or its precursor BLASTZ. It consists of an arranged blocks of DNA sequences organized in the form of matrices. The LAV files can be used to identify similar structural and functi...
