There are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). This sequence is broken into a series of three-nucleotide units known as codons. Each DNA sequence that contains instructions to make a protein is known as a gene.
Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
DNA sequencing was built upon earlier knowledge of DNA polymerases and cell-free systems for replicating DNA. The chain-termination method, which makes clever use of a "defective" DNA nucleotide, now dominates DNA sequencing technology.

I am pretty sure that the answer is D. The entire sequence of human DNA was identified.
I don't have any evidence that this is the answers, just that while reading my textbook, it said that the project identified the entire sequence of human DNA, so it was pretty much a word for word answer. I hope this helps!!!
Answer:
1 All living organisms are made up of one or more cells.
2 The cell is the basic structural and functional unit of life.
3 Cells arise from pre-existing cells.
Explanation: if this is not correct plz tell me and ill do some more research but im pretty sure its correct.
The word in the blank should be 'segregation' :)
