How many different DNA nucleotides are there?

Answer 1

There are five types of nucleotides found in nucleic acids.

In DNA there are four types of nucleotides, each containing one of four bases adenine (A), thymine (T), guanine (G) and cytosine (C).

In RNA there are also four types of nucleotides but the base thymine is replaced by uracil (U).

So in total there are five types of nucleotides, but any DNA or RNA molecule will only contain four of them.

Answer 2

In DNA. each nucleotide consists of three parts: 1. One deoxyribose molecule 2. One phosphate group 3. One nitrogenous base (Adenine, Guanine, Thymine and Cytosine) Since each nucleotide carries only one of four possible nitrogenous base, there are are four possible different DNA nucleotides. In RNA each nucleotide consists of three parts: 1. One ribose molecule 2. One phosphate group 3. One nitrogenous base (Adenine, Guanine, Uracil and Cytosine) Note: Uracil takes the place of Thymine in RNA Since each nucleotide carries only one of four possible nitrogenous base, there are are four possible different RNA nucleotides.

Answer 3

we haven't found all of them yet so I can't tell you, most likely in the tens of billions

The answer above is correct if your talking about how many nucleotides are contained in DNA. But they all consist of 4 nucleotides 2 made of purine bases which are adenine and guanine and 2 pyrimidine bases which are thymine and cytosine. The purine based nucleotides always pair with their base pair pyrimidine based nucleotide. In DNA Adenine is paired with thymine and guanine pairs with cytosine. But if it's RNA there is a special exception which replaces thymine with Uracil pairing with adenine.

These nucleotides when turned into RNA and transported to a ribosome are read off in sequences of 3 which can correspond to start sequence, stop sequence and any amino acid. After the ribosome has read the start sequence it starts running down the RNA and adds the Amino acids in the sequence read in the three nucleoside containing codons. Finally, when the stop sequence is read the ribosome stops the chain of amino acids and then you have a protein which your DNA coded for which your body uses for creating many parts of our body in a way which determines your traits such as eye color, hair color, pre-determining factors of if you will have a disease. It's unending and we really are currently studying our DNA to see how we could use it in many medical therapies or to see ahead to help prevent diseases you are predetermined to have in your DNA.

Answer 4

Halloween costumes can be lots of fun. Many people enjoy shopping for a unique look that suits their personal style. The problem many people encounter during this time of year is that costume prices can get a bit steep. If you are living on a tight budget, then you may not have room for a full price Halloween costume purchase. Luckily there are a few ways you can save money so you don't have to skip out on the costume while enjoying the seasonal festivities this year.

Watch Costume Seller Ads

As Halloween nears, many costume sellers begin offering sales and special deals on their merchandise. Look for fliers and advertisements and check online for coupon codes and other money saving opportunities. You may be able to purchase your favorite Halloween costumes at a great discount if you are willing to do a little leg work and search for discounts. Always check for expiration dates because the discount may not extend all the way to Halloween.

Start Shopping As Early As Possible

The earlier you can begin shopping, the more chances you will have to find low prices on the costumes you want. If your outfit requires multiple pieces, then you may be able to stretch out your purchase over a few weeks or months. This allows you to spend smaller dollar amounts while putting together your costume. The earlier you shop, the more sales you will encounter that could help you lower the total cost of each Halloween costume you buy.

Browse the Clearance Costumes First

Before you hurry over to the new costume shopping area, look for any special sale or clearance sections the retailer may have. This is usually a small collection of products from previous years that are available at deep discounts. Simple items like feather boas, eye patches and more never expire however the retailer still must clear them out to make room for new products. You could benefit by finding last year's Halloween costumes at significantly lowered prices.

Answer 5

There are two strands of nucleotides in DNA, while there only being one strand in RNA

Answer 6

There is no exact number. It varies on the DNA molecule. A DNA molecule may be composed of more than 20.000 Nucleotides

Answer 7

There are four nucleotides that make up DNA, each defined by the nitrogenous bases they contain. They are named adenine, thymine, guanine and cytosine.
