For DNA polymerase to link nucleotides together as new strands of DNA the first nucleotide must be attached to what because DNA polymerase can only add nucleotides to a pre exsisting strand?
RNA Primer
Why are ddNTPs used for DNA sequencing?
Because on the addition of the normal ddNTP to the sequencing, there will be addition of another nucleotide added by DNA polymerase which keeps DNA sequencing going.
Why is DNA polar?
Yes, nucleotides are polar. Nucleotides are the building blocks of DNA and are made up of 3 things - a phosphate group (huge indication that it's polar, it has a negative charge of -3), a 5 carbon sugar (it has polar OH hydroxyl groups) and a nitrogen base (not polar). Overall, the entire nucleotide together is polar.
Unlike DNA polymerase RNA polymerase do not have proofreading activity why is this not determinental to cell?
because they produce such large amounts of the Rna
Why RNA-primer only initiates replication?
Laxu's answer made no sense so I deleted it. Next time Laxu please contribute something that makes some grain of sense. Only RNA primers can be used because DNA polymerase cannot add nucleotides without an existing 3-OH' to build on. RNA can be added to an existing template without this requirement and is then used by the DNA polymerase to initiate the strand.

Where is DNA located in the nucleotide?
This question is strange because nucleotides make up DNA.
Smallest bit of genetic information?
A gene, because any smaller and it would just be nucleotides.
Which enzyme links RNA nucleotides together to form an RNA molecule?
Enzyme RNA polymerase joins nucleotides together
What is the prinicpal enzyme involved in DNA replications because it jois individual nucleotides to produce a DN A molecule?
DNA polymerase III .
What major class of macromolecules does ATP belong to?
Nucleotide because it also contains a phosphate group as well as a nitrogenous base.
Are nucleotide and nitrogenous base and nucleic acid related to each other?
yes, they are related. they are related to each because nucleic acids are composed of nucleotides. Each nucleotide has a single or double ringed nitrogen base.
Why are ddNTPs used for DNA sequencing?
Because on the addition of the normal ddNTP to the sequencing, there will be addition of another nucleotide added by DNA polymerase which keeps DNA sequencing going.
How many nucleotides would be in the strand c c g t c a a g t a c g?
Each of these letters stands for a base (which is part of one nucleotide). Therefore because there are 12 bases, there would be 12 nucleotides in the strand.
Why can't DNA polymerase synthesize a new strand of DNA without the help of a RNA primer?
Because DNA Polymerase requires the OH on the 3' as an active site. It uses the OH on the 3' end of a nucleotide to attach a phosphate from the 5' end of the next nucleotide. It only works in this direction, and that is why DNA polymerase works 5' to 3'.
How many strands of nucleotides are in DNA?
Thousands upon thousands. Because DNA must contain all the characteristics of your being, it must be long.
