Answer:DNA is shown to be the genetic material in bacteria and some phages.
DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed
Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.
DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence
Explanation:
1. Lipds is another macro molecule with different subnits of fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.
2 The correlation of action and absorption spectra varies with different organisms DNA. e..g in viral cells there is a wide difference between the absorption and action spectra, that is no correlation, while some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.
