Answer:
Explanation:
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
Answer:
b) plasmid
Explanation:
A plasmid is an extrachromosomal DNA molecule that found in a cell that replicates independently without the need for chromosomes. A plasmid is small and is also not attached to the chromosomal DNA. Generally, plasmids are a circular piece of double stranded DNA materials that are present in bacteria.
Plasmids are used in a molecular biology laboratory for gene manipulation. they are able to transfer genes to a DNA through DNA recombinant technology and also aid DNA replication in bacteria. Plasmids are also used to study antibiotic resistance.
