Which statement is true about genetic information? A gene is a section of DNA and is found on a chromosome in the cell's nucleus. A gene is a section of DNA and is found on a chromosome in the cell's nucleus. A DNA molecule is a section of a gene found on the nucleus of chromosome. A DNA molecule is a section of a gene found on the nucleus of chromosome. A chromosome is a section of a gene found in the nucleus of a DNA molecule. A chromosome is a section of a gene found in the nucleus of a DNA molecule. The nucleus of a cell contains genes that are made up of chromosomes composed of DNA.

With respect to genetic information, it is true that a gene is a section of DNA and is found on a chromosome in the cell's nucleus.

Explanation:

DNA contains all the genetic information that determines the morphological and functional characteristics of living beings.

The structure of DNA contains specific sequences of 4 nitrogenous bases, whose extension constitutes the coded genetic information. A chromosome is formed by a DNA molecule, and the genes contained in the chromosome locus are sequences of nucleotides coming from fragments of that same DNA.

All the genetic information —DNA, chromosomes and genes— is located in the cell nucleus.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
