Are no two nucleotide sequences in DNA molecules ever the same?
Yes. This can happen via a gene duplication in a single organism or by shear coincidence (though its increasingly unlikely the biggest the sequence in question). Identical sequences can happen across species due to heredity from a common ancestor of a common gene or genetic marker, such as we see in ERVs and analysis from computational genomics.
What acts as interpreter molecules that recognize specific amino acids and nucleotide base sequences?
tRNA (Transfer RNA)....It is often mistaken with mRNA
What if we could see the individual nucleotide sequences of DNA?
You can see the nucleotide sequences in the DNA. It is called as DNA finger printing. It has got many applications in molecular biology.
How man different possible base sequences are there in a nucleotide chain three nucleotides in length?
3! = 6 different sequences =================
What refers to identifying an individual on the basis of repetitive nucleotide sequences in his or her DNA?
DNA fingerprinting

DNA replications begins in areas of DNA molecules called?
replications origins, which are highly conserved DNA sequences that are recognized by the replication machinery.
The set of three nitrogen bases on tRNA that is complementary to an mRNA codon is called?
These nucleotide sequences are called anticodons.

What are three things that scientists use nucleotide sequences to determine?
punk
What is the function of neucleotide base molecules?
Nucleotide base molecules (adenine, thymine, cytosine, and guanine for DNA; adenine, uracil, cytosine and guanine for RNA) are molecules that make up genetic material. They are bound to a phosphate backbone, and because their specific sequences (in codons, groups of three nucleotide bases in a row) make up the genes that code for proteins, nucleotide bases essentially contain the genetic information needed to manufacture most structures within our bodies.

How are nucleotide sequences used to put organisms in evolutionary order?
When comparing nucleotide sequences in organisms, we find that the organisms that have less differences in their nucleotide sequences are closer related in the evolutionary tree. By this we mean that the common ancestor from which these two organisms evolved is more modern than the ancestor they might share with an organism that shows more difference in the DNA sequencing. Example: the chimps and humans share a common ancestor that is relatively modern because the difference in their nucleotide sequences is just about 1% but the differences between the nucleotide sequence of humans and fish shows lots of differences which shows their common ancestor y much older than the one with chimps.

He nucleotide sequences on DNA that actually have information encoding a sequence of amino acids are?
