Answer:

This can only be due to the fact that the Universe is expanding. Further, by measuring the distance to the galaxies, one finds that the velocity of recession is proportional to the distance of the galaxy from us. This is called Hubble law after Edwin Hubble who was the first to discover it.

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

Svetlanka [38]

Answer:

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.
