What is the flow of genetic information during protein synthesis?
Question: Identify the flow of genetic information during protein synthesis in a eukaryotic Cell. Transcription produces an mRNA molecule in the nucleus. The mRNA moves to the cytoplasm where translation occurs. mRNA moves a protein to the DNA and makes a copy of the DNA through translation.

The basic flow of genetic information in biological systems is often depicted in a scheme known as "the central dogma" (see figure below). This scheme states that information encoded in DNA flows into RNA via transcription and ultimately to proteins via translation.

What is the direction of DNA transcription?
Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. At this point, RNA polymerase begins moving down the DNA template strand in the 3' to 5' direction, and as it does so, it strings together complementary nucleotides.

DNA is always synthesized in the 5'-to-3' direction, meaning that nucleotides are added only to the 3' end of the growing strand.

Information encoded in DNA is transcribed to RNA and RNA is translated to a linear sequence of amino acids in protein. The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system.
What is the process of translation?
Translation is the process by which information in mRNAs is used to direct the synthesis of proteins. As you have learned in introductory biology, in eukaryotic cells, this process is carried out in the cytoplasm of the cell, by large RNA-protein machines called ribosomes. Ribosomes contain ribosomal RNAs (rRNAs) and proteins. The proteins and rRNAs are organized into two subunits, a large and a small.
Why is DNA copied?
As the cell’s so-called blueprint, DNA must be copied to pass on to new cells and its integrity safeguarded. The information in the DNA must also be accessed and transcribed to make the RNA instructions that direct the synthesis of proteins.
How do cells make new cells?
The only way to make new cells is by the division of pre-existing cells. This means that all organisms depend on cell division for their continued existence. DNA, as you know, carries the genetic information that each cell needs. Each time a cell divides, all of its DNA must be copied faithfully so that a copy of this information can be passed on to the daughter cell. This process is called DNA replication.

What are some examples of speciation?
Examples of speciation affecting gene flow. When gene flow is blocked by physical barriers, this results in Allopatric speciation or a geographical isolation that does not allow populations of the same species to exchange genetic material. Physical barriers to gene flow are usually, but not always, natural.
How does urbanization affect bobcat migration?
Another example of urban facilitation is that of migrating bobcats ( Lynx rufus) in the northern US and southern Canada. A study by Marrote et al. sequenced fourteen different microsatellite loci in bobcats across the Great Lakes region, and found that longitude affected the interaction between anthropogenic landscape alterations and bobcat population gene flow. While rising global temperatures push bobcat populations into northern territory, increased human activity also enables bobcat migration northward. The increased human activity brings increased roads and traffic, but also increases road maintenance, plowing, and snow compaction, inadvertently clearing a path for bobcats to travel by. The anthropogenic influence on bobcat migration pathways is an example of urban facilitation via opening up a corridor for gene flow. However, in the bobcat's southern range, an increase in roads and traffic is correlated with a decrease in forest cover, which hinders bobcat population gene flow through these areas. Somewhat ironically, the movement of bobcats northward is caused by human-driven global warming, but is also enabled by increased anthropogenic activity in northern ranges that make these habitats more suitable to bobcats.
How does urbanization affect gene flow?
There are two main models for how urbanization affects gene flow of urban populations. The first is through habitat fragmentation, also called urban fragmentation, in which alterations to the landscape that disrupt or fragment the habitat decrease genetic diversity. The second is called the urban facilitation model, and suggests that in some populations, gene flow is enabled by anthropogenic changes to the landscape. Urban facilitation of gene flow connects populations, reduces isolation, and increases gene flow into an area which would otherwise not have this specific genome composition.
Why is gene flow important?
Genetic rescue. Gene flow can also be used to assist species which are threatened with extinction. When a species exist in small populations there is an increased risk of inbreeding and greater susceptibility to loss of diversity due to drift.
Why do finches have fragmented populations?
This is due to adaptive radiation, or the evolution of varying traits in light of competition for resources. Gene flow moves in the direction of what resources are abundant at a given time.

A cryptic species is a species that humans cannot tell is different without the use of genetics .

What is the purpose of mRNA?
The mRNA is used as the template for the creation of the amino acid sequence of proteins (in translation ). Here, two different sets of information are shown. The DNA sequence is slightly different, resulting in two different mRNAs produced, followed by two different proteins, and ultimately, two different coat colors for the mice.
mRNA Translation
- During the process of gene expression and protein synthesis, cells transfer the genetic information from DNA to mRNA. During this process, the mRNA serves as a template for assembling the proteins. Translation is the second step of gene expression and is considered central to genetics. It is also the second stage of protein synthesis. mRNAs have a ...
DNA Replication
- DNA replication is a highly complex process that duplicates the entire genetic content of a cell. The steps of this process are intricately orchestrated to ensure minimal error. The replication machinery makes fewer than one error per billion nucleotides copied, which is equivalent to copying 100 dictionaries of 1000 pages each. DNA replication begins with a process called prim…
RNA Transcription
- RNA plays many roles in the flow of genetic information, ranging from storing genetic information to translating information into proteins. It also has the ability to act as an enzyme to self-edit the genetic code. There are thousands of genes, each of which dictates how cells function. The flow of genetic information varies according to the type of RNA. Genes have different levels of transc…
mRNA Decay
- There are two main pathways for mRNA degradation. The first, known as deadenylation, involves a shortened polyA tail which attracts degradation machinery. The second, known as nonsense-mediated decay, bypasses the decapping process and removes mRNA by itself. Both pathways involve the same enzymes, but the mechanism used to remove mRNA is different. The stability …
Protein Synthesis
- Protein synthesis is the process by which genetic information is translated into amino acids. Each amino acid consists of three nucleotides. The genetic code is organized so that there is no overlap in its bases. This makes it possible to transfer genetic information to the next cell in the body in a process called translation. The genetic code consists of 64 codons. Each codon specif…
