The tetranucleotide hypothesis stated what?
A
There were four nucleotides
B
The four nucleotides were repeated again and again, making up chromosomes
C
Only one of the four nucleotides is used for genetic storage
D
Four nucleotide repeats encode for a protein necessary for genetic storage
Verified step by step guidance1
Understand the context of the tetranucleotide hypothesis, which was an early 20th-century idea about the structure of DNA.
Recognize that the hypothesis suggested DNA was composed of repeating units of four nucleotides in a fixed sequence.
Identify the four nucleotides involved: adenine (A), thymine (T), cytosine (C), and guanine (G).
Clarify that the hypothesis implied these nucleotides were repeated in a simple, monotonous pattern, which was later proven incorrect.
Acknowledge that the correct understanding of DNA involves a complex sequence of nucleotides, allowing for genetic diversity and information storage.
