Question

The function of chromosome of carrying the genetic information from one cell generation to another is performed by

• A. RNA
• B. DNA
• C. Histones
• D. Calcium

Answer 1

Answer: (B)

DNA

The function of chromosome of carrying the genetic information from one cell generation to another is performed by DNA. The information carried by DNA is held in the sequence of pieces of DNA called as genes. Transmission of genetic information in genes is achieved via complementary base pairing. For example, in transcription, when a cell uses the information in a gene, the DNA sequence is copied into a complementary RNA sequence through the attraction between the DNA and the correct RNA nucleotides. Usually, this RNA copy is then used to make a matching protein sequence in a process called translation, which depends on the same interaction between RNA nucleotides.

So, the correct answer is option B.
