Answer:
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
A gene is spliced by assembling different gene segments and DNA sequences into a product called a chimera. Scientists join these snippets in a circular piece of DNA called a plasmid. Scientists use a complex process to clone genes from an organism's DNA.
Answer:through carbon cycle
Explanation: look up for the word and also look at the diagrams for better understanding
Answer:
53°.
Explanation:
Rhese method can be used to identigy the orbital projectioons of the organism. The median sagittal plane are specified at the particular angles to obtained the projections.
IR in parieto-orbital projection and median sagittal plane by the rhese method forms the angle of 53° in the projections. These projections are important for the medical diagnosis of individual.
Thus, the correct answer is option (C).
