How is the hereditary information in DNA coded and passed from generation to generation?

Question

Daniel Arnold · Accepted Answer

The hereditary information is coded in groups of three bases. These are a double strand so that 1 strand is a mirror image of the other stand and can be copied

The information is stored in a manner akin to computer codes, complete with information on the code and instructions on how to read it. The enormous amount of complex information found on DNA is coded by only four different types of bases: codons, a group of three bases that store information that can either code for an amino acid or for instructions about what to do with the proteins formed by the amino acids. On the opposing strand of DNA, A consistently joins with T, and C consistently joins with G. One double strand can be copied into two copies of the original double strand when the DNA splits into two complimentary strands. Each strand can then make a copy of its complement, with the A forming a new T and the T forming a new A. One unsolved question remains to be the origin of the intricate information found on DNA.

undefined The hereditary information in DNA is coded in the sequence of nucleotides, which are the building blocks of DNA. This information is passed from generation to generation through the process of DNA replication during cell division, where each strand of the DNA molecule serves as a template for the synthesis of a new complementary strand. Additionally, during sexual reproduction, genetic information from both parents is combined to form a unique combination in the offspring.
