Was the tetranucleotide hypothesis in DNA correct or incorrect?

The tetranucleotide hypothesis said that DNA wasn't diverse enough to be the hereditary/genetic material.
In case anyone gets confused (just indulge me so that I can feel smart), let me explain what the tetranucleotide hypothesis was.
It was hypothesized by Phoebus Levene in 1910, a bit after he identified the components of DNA. He proposed that the four nucleotides (adenine, thymine, cytosine, and guanine) occurred in equal quantities - as in A=T=C=G. This idea was extended to the point where it was widely believed that these four nucleotides continued in a repetitive pattern. Because of this, DNA didn't seem like a likely candidate for genetic material. Instead, proteins (the histones in chromosomes) were believed to be the real genetic material.
This belief was held steadfastly because Levene was widely respected. Sadly, many scientists second guessed themselves or were not taken seriously because of this hypothesis. Avery&McCarty&MacLeod met such criticism.

How often does the cellular machinery that replicates DNA insert an incorrect base?
not often
Can polymerase catch and correct every reptication error?
Yes. Initially, DNA replication makes 1 mistake in a 100,000. Like spell check, DNA polymerase comes in and removes errors in base pairs and correct them by adding the right ones. After DNA polymerase checks the new strand for errors, the end result is 1 mistake in a billion. If this didn't occur, mutations would surely take place in out body.
The molecule that stores the information about the order of amino acids in a protein is?
DNA (RNA is incorrect)
What statement is correct regarding the cells and DNA?
all the cells have identical DNA
How are mutations prevented during DNA replication?
DNA polymerase checks DNA for errors.DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.
What is an incorrect copy of DNA known as?
An incorrect copy of DNA is also known as a mutation.
What is the hypothesis for strawberry DNA project?
what is it
What is an incorrect DNA copy called?
An incorrect copy is called a mutation.
What is an incorrect copy called in DNA?
An incorrect copy is called a mutation.
What is an incorrect copy is known as?
An incorrect copy of DNA is also known as a mutation.
What was james watsons hypothesis for the structure of the dna?
KEY FACT In 1953, James Watson and Francis Crick put forward their hypothesis that DNA had a double helix structure. Their first attempt to identify the structure of DNA was not successful, however, in 1953 they put forward their hypothesis that DNA had a double helix structure.
What is a hypothesis for extracting banana DNA?
Yes dickface
How can finding out that a hypothesis is not true be useful for hypothesis?
So they know not to make the same mistake again
Can DNA polymerase catch and incorrect every replication error?
no
What was the first DNA model called?
The first correct shape was the double helix by Watson and Crick. However, there were earlier incorrect models, for example the incorrect triple helix model proposed by Linus Pauling. Even the first model by Watson and Crick turned out to be incorrect; they had it inside out compared to the correct model.
How often does the cellular machinery that replicates DNA insert an incorrect base?
not often
If two species have similar DNA what hypothesis is supported?
The hypothesis supported is that the two species share a common ancestor and have evolved from a common gene pool. This similarity in DNA suggests that they are closely related evolutionarily.
