Nucleotide Sequence Quotes

It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.

DNA, like a tape recording, carries a message in which there are specific instructions for a job to be done.

Do codons overlap? In other words, as we read along the genetic message do we find a base which is a member of two or more codons? It now seems fairly certain that codons do not overlap.

It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid.

A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.

Different viral species contain nucleic acids that differ not only in length and nucleotide sequence but in many unexpected ways as well.

We are beginning to shift into life code. And in the process of shifting into life code, every life form on this planet is coded in a double helix with a sugar phosphate backbone. And that codes whether you become a bacteria, an orange, a lemon, a Lemur, a Cow, a sheep, a human being, a politician, any one of these things is all coded in this four-letter code.

There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Telomeres are the protective caps at the ends of chromosomes in cells. Chromosomes carry the genetic information. Telomeres are buffers. They are like the tips of shoelaces. If you lose the tips, the ends start fraying.

We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going.

When you click on a link, you are replicating the string of code that it links to. Replication of code sequences isn't life, any more than replication of nucleotide sequences is, but we know that it sometimes leads to life.

Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid.

The greatest single achievement of nature to date was surely the invention of the molecule DNA.

All life is nucleic acid; the rest is commentary.

How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.

DNA is like Midas's gold, everyone who touches it goes mad.

Genes are biochemical recipes written in a four-letter alphabet called DNA.

The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority.

The river of my title is a river of DNA, a river of information, not a river of bones and tissues

We have come a long way on that old molecule DNA.

Genes are little items that are found in every living thing except Sen. Alfonse D'Amato.

Three billion bases of DNA sequence can be put on a single compact disc and one will be able to pull a CD out of one's pocket and say, 'Here is a human being; it's me!'

The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life.

What lies at the heart of every living thing is not a fire, not warm breath, not a 'spark of life.' It is information, words, instructions... If you want to understand life, don't think about vibrant, throbbing gels and oozes, think about information technology.
