Answer:
HIV is called a retrovirus because it works in a back-to-front way. Unlike other viruses, retroviruses store their genetic information using RNA instead of DNA, meaning they need to 'make' DNA when they enter a human cell in order to make new copies of themselves.
Explanation:
Answer
Pacific Plate, oceanic tectonic plate
Explanation:
the large brown plate is <u>pacific plate</u> was under the ocean and also named after the <u>ocean</u> <u>pacific ocean.</u> so it is easy to guess
hope you understood it . it was my explanation <u>up</u> for more info <u>down</u> i have pasted what they told in google.
Pacific plate
In fact, six of the seven major tectonic plates are named after the continents they contain. The one exception is the Pacific plate, which lies beneath the Pacific Ocean. Not only is this the only major tectonic plate that is mainly underwater, it is also the largest, spanning over 100 million square kilometers.
Pacific Plate. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units.
Answer:
plasmid
Explanation:
Plasmids are small circular double or singe stranded DNA molecules that are distinct from the main chromosomal DNA. They are used in genetic engineering as vectors for replication of foreign DNA or proteins using bacteria as a host organism. The DNA strand is integrated into the plasmid DNA to form a recombinant plasmid that is then transformed into the host.
Plasmids are ideal vectors because of the following characteristics:
- High copy number per cell
- Multiple cloning sites
- Have an origin of replication
- Have antibiotic resistance gene
There are also diffrent types of plasmids:
- Degradative
- Virulence
- Resistance
- Fertility
- Col plasmid
