Difference Between Prokaryotic And Eukaryotic Transcription
A process by which the information stored in the DNA is transferred to an mRNA through the synthesis of RNA is known as transcription. In spite of the similar overall…
Inhibitors of Transcription or Translation
Bacteria, like mammalian cells, must synthesize proteins for self-maintenance and replication. DNA serves as the "instruction manual;" it provides the information necessary for protein synthesis. The first step in this…
Steps of Genetic Transcription
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to…
What Are mRNA, rRNA and tRNA?
RNA is a critical component of every single living cell in the universe. Without it, life as we know it could not exist. There are three types of RNA, each…
D-loop replication
D-loop replication is a proposed process by which circular DNA like chloroplasts and mitochondria replicate their genetic material. An important component of understanding D-loop replication is that many chloroplasts and mitochondria have a single circular chromosome like bacteria instead of the linear chromosomes found in eukaryotes. However, many chloroplasts and mitochondria have…
Non-coding DNA
The vast majority of the human genome is comprised of non-coding DNA (genes only account for ~ 1.5% of the total sequence) § Historically referred to as ‘junk DNA’, these non-coding regions are…
Inhibition of Nucleic Acid Synthesis
In a bacterial cell, or any kind of cell for that matter, the nucleic acids DNA and RNA are incredibly important molecules. When a cell divides, it must first replicate…
DNA Sequencing
DNA sequencing refers to the process by which the base order of a nucleotide sequence is elucidated § The most widely used method for DNA sequencing involves the use of chain-terminating…
Okazaki Fragments
DNA polymerase cannot initiate replication, it can only add new nucleotides to an existing strand For DNA replication to occur, an RNA primer must first be synthesised to provide an attachment point…
How DNA Works
DNA Replication The double helix of DNA unwinds and each side serves as a pattern to make a new molecule. DNA carries the information for making all of the cell's…
