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.

A man who is aware that he is a silent carrier of the FMO3 ""fish odor syndrome"" gene has children with a woman who is ""normal
Leya [2.2K]

Answer:

This could be possible if the  wife  is a carrier of the FMO3 allele.   Therefore the two carrier parents must have  passed the defective alleles to the child, who now possessed the gene for the FMO3, and said to be dominant for the fish odor.

In genetics a Carrier  is an individual who inherited a defective allele (FMO3) , but do not show the manifestations of the allele, or symptoms of the diseases attributed to it. Therefore the wife is a Carrier for the allele if the child could show this symptoms of fish odor.
