DNA: Complementary Base Pairing

what is the complementary dna base sequence to the dna strand tgccat? This is a topic that many people are looking for. voteyesons.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, voteyesons.org would like to introduce to you DNA: Complementary Base Pairing. Following along are instructions in the video below:
Previously on dna and rna. The testimony of my expert witness will not only clear clear my client of all wrongdoing. But will also reveal the identity of the true of our poor departed.
Mr. Bones. Nucleic acids are the molecules that cells use to store transfer and express genetic information dna stands for deoxyribonucleic acid its the molecule which stores genetic information in an organism that makes the nucleotide the most basic subunit of dna or more generally of any nucleic acid.
So professor. You told us that a dna nucleotide consists of a phosphate group a sugar and a nitrogenous base can you tell us how nucleotide structure pertains to the case at hand. Oh yes.
You see you need to understand the chemistry behind dna to fully. Appreciate the importance and function of the molecule. The phosphate group and sugar are the same in every nucleotide.
But there are four different nitrogenous bases guanine adenine thymine and cytosine.

They are often abbreviated by the first letter of each nitrogenous base g. A t and c. They essentially function as a four letter alphabet or if i may make an analogy to the case at hand the information in dna is like a recipe in one of our poor victims cookbooks reading the dna code ultimately tells a cell.
How to make proteins that it can use to perform various functions necessary for life for instance reading a specific sequence of dna tells one cell. How to make hemoglobin protein to carry oxygen molecules throughout the body on the other hand. Another cell might read a different recipe.
Which tells it how to make insulin protein to control blood sugar levels. Oh and reading or transcribing dna is really an intriguing process yes professor im sure dna transcription is very interesting but lets stick to the characteristics of dna that pertain to the trial at hand you were telling us about the nitrogenous bases. Oh.
Yes. Youre quite right the bases can be categorized into two different groups. The single ring nitrogenous bases thymine and cytosine are called pyramidal and the double ring.
Bases.

Adenine and guanine are called purines. Oh. Yes.
I guess you might wonder how i can remember that. But its really quite simple. All gods are pure adenine and guanine are purines and by process of elimination that means cytosine and thymine have to be perimeters.
See yes. Yes. Thats a very nice mnemonic aid.
Adenine and guanine are purines. But were getting off track. You were telling us.
Why the chemical structure of nucleotides is important.

Oh yes. The chemistry of nitrogenous bases is really the key to the function of dna. It allows something called complementary base pairing.
You see cytosine can form 3 hydrogen. Bonds with guanine and adenine can form two hydrogen bonds with thymine or more simply c. Bonds with g and a bonds with t.
It is called complementary base pairing because each base can only bond with a specific base partner. The structures complement each other in a way. Like a lock.
And key c. Will only bond with g. And a will only bond with t in dna because of complementary base pairing.
The hydrogen bonded nitrogenous bases are often referred to as base pairs. Remember how i said that dna paulino clea tides. Look like .
