What is organism specific database?
MODs, or organism-specific databases, describe genome and other information about important experimental organisms in the life sciences and capture the large volumes of data and information being generated by modern biology.
What types of relationships do we have with the microbial world?
There are three types of symbiotic relationships in which humans and bacteria coexist. The types of symbiosis are termed commensalism, mutualism, and parasitism.
What is an example of a mutualistic relationship between humans and bacteria?
When two species benefit from each other, the symbiosis is called mutualism (or syntropy, or crossfeeding). For example, humans have a mutualistic relationship with the bacterium Bacteroides thetaiotetraiotamicron, which lives in the intestinal tract.
What are some examples of symbiotic relationships with bacteria?
Some examples of symbiotic microbial communities which exist in nature include:
- Gut microbial communities.
- Symbiotic communities in root nodules.
- Colonization of skin by beneficial bacteria.
- Nematode Worms.
- Thermal Vents.
Which of the following is a model organism database?
The Zebrafish Information Network (ZFIN) is a database for the model organism zebrafish , which includes data on genes, mutations, phenotypes, genotypes, gene expression, orthology, and nucleotide and protein sequences.
Why is E. coli model organism?
Because there are tools available to manipulate the genome of E. coli, it is a good candidate as a model organism for metabolic engineering; this is where E. coli is genetically manipulated so that it becomes able to produce desired chemicals from various sources during growth.
Is SGD a model organism database?
The Saccharomyces Genome Database (SGD; http://www.yeastgenome.org) is an expertly curated database of literature-derived functional information for the model organism budding yeast, Saccharomyces cerevisiae.
What are the three types of relationships in database design?
The 3 Types of Relationships in Database Design. 1 One-to-One. A row in table A can have only one matching row in table B, and vice versa. This is not a common relationship type, as the data stored in 2 One-to-Many (or Many-to-One) 3 Many-to-Many.
What is an example of a relational database?
Relationships are the cornerstone of relational databases. Users can query the database and get results that combine data from different tables into a single table. For example, if you own a record store, the database might have a table for albums, another for song titles, and another for artists.
What is a relationship between Records in a database?
In databases, there are a few different terms to describe the relationships between records. This the least common type of relationship, but it’s the easiest to visualize. In this relationship, there is one and only one record on each side of the relationship. Each row in a table is connected to a single row in another table.
How many types of relationships can exist between two entities?
There are three types of relationships that can exist between two entities. Such a relationship exists when each record of one table is related to only one record of the other table. For example, If there are two entities ‘Person’ (Id, Name, Age, Address)and ‘Passport’ (Passport_id, Passport_no).
