Which statement best describes the role of dna ? it transmits genetic information to the next generation. it speeds up chemical reactions inside of cells. it directly forms proteins. it provides a form of energy for cells.

It transmits genetic information to the next generation

Explanation:

DNA stores information on how the cell should be made and ‘run’. This is why it is critical that its integrity is well preserved. Otherwise, mutations on DNA can be lethal to the cell. In higher cells, DNA is protected in the nucleolus. To pass down the genetic information, DNA is replicated by DNA polymerases and then during cell division, either copy of the pair goes to each of the two daughter cells.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
