DNA is nothing more than a sequence of bases (nucleotides) and since DNA is normally double stranded, they can be referred to as base pairs. One could best visualise it like a zipper: two connected strands (that can also be separated). DNA is made up of only four different bases, abbreviated as A, C, G and T. These always form the same pairs: A on one side of the zipper, T on the other side and the same goes for C and G. So, when unzipped, you always know the sequence of the opposite strand.

The sequence of base pairs that make up our DNA should be viewed like a bar code. Every set of three bases code for one building block of a protein. That's all that DNA is for: code for building proteins. A set of three bases is called a codon and tells machinery in the cell (ribosome) to add one specific building block to a forming protein. It's like LEGO and DNA is the instructions that tell you which block to add next.

These different blocks give shape and function to the proteins it helps to build.

What is the name of the enzyme that would have placed nucleotides into the replicating DNA in the correct order?

The enzyme responsible for placing nucleotides into replicating DNA in the correct order is called DNA polymerase. DNA polymerase adds complementary nucleotides to the growing DNA strand during replication, following the rules of base pairing (A with T and C with G).

Determining the exact order of nucleotides in DNA is called?

Determining the exact order of nucleotides in DNA is called DNA sequencing. This process helps in identifying the sequence of bases (adenine, thymine, cytosine, and guanine) in a DNA molecule, which is crucial for understanding genetic information and studying various biological processes.


The genetic code on DNA depends on the order of?

The DNA message depends upon the order of the 4 nucleotides available. These nucleotides arrange into specific patterns based on genetic information.


How many nucleotides are present in the DNA sequence?

The number of nucleotides in a DNA sequence can vary, but in general, a human DNA molecule contains about 3 billion nucleotides.


What are the arrangement of nucleotides in DNA called?

The arrangement of nucleotides in DNA is called the DNA sequence. It consists of a specific order of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). This sequence encodes genetic information that determines an organism's traits and functions.
