Maximum number of bases in plasmid discovered so far is
1 50 kilobase
2 500 kilobase
3 5,000 kilobase
4 5 kilobase
Explanation:
Plasmids have a wide range of length from roughly one thousands DNA base pairs to hundreds of thousands of bases pairs. - Plasmids are known to vary from 5 to 500 kilo base in size although plasmid as small as 2 kilo base to as large as more than $1 \mathrm{mb}$ in size has been reported.

What is true for archaebacteria?
1 All are halophilic
2 All are photosynthetic
3 All are fossils
4 These are oldest living beings
Explanation:
The oldest living organisms on earth are known as Archaebacteria. They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope. - Archaebacteria have the capability to produce methane.

The red color of red sea is due to which of the following blue-green algae?
1 Chlamydomonas nivalis
2 Anabaena
3 Microcystis
4 Trichodesmium
Explanation:
Trichodesmium is a diazotroph that is fixes atmospheric nitrogen into ammonia a nutrient used by other organisms. - Trichodesmium is thought to fix nitrogen on such a scale that it accounts for almost half of the nitrogen fixation in marine systems globally. - Trichodesmium are Cyanobacteria also known as blue-green algae. - It is widely accepted that the red sea is caused by Trichodesmium.

Nuclear membrane is absent in
1 Monera
2 Protista
3 Fungi
4 Plantae
Explanation:
The nuclear membrane is a double layer that encloses the cells nucleus, where chromosome reside. Nuclear membrane are absent in kingdom Monera, because here all organism are unicellular prokaryotes. - Nuclear membrane separate the chromosome from the cells cytoplasm and other contents. - It provide the structural framework of the nucleus. - The nuclear membrane acting as barrier that prevent the free passage of molecules between the nucleus and the cytoplasm.
