What is the difference between an endonuclease and an exonuclease?
an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
What is a polynucleotide?
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
The struct of RNA?
RNA is a single polynucleotide chain.
What has the author Roshan Shafai written?
Roshan Shafai has written: 'The polynucleotide structure of a germin gene'
What do polynuceotides do?
do you mean Polynucleotide?eg.en.wikipedia.org/wiki/Polynucleotide
Which component of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
all i know is that its not phosphate
In DNA molecule how many polynucleotide strands are present?
2 polynucleotide strands make up a DNA and these strands are held togatehr by hydrogen bonds. In D.N.A there are 2 polynucleotide strands in R.N.A there is usually 1 polynucleotide strand.
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The part of a nucleotide that can be removed without breaking the chain is the thymine for DNA and the uracil for RNA. These two components are the nucleobases of a nucleotide.
How many polynucleotide strands do RNA have?
1
What chain is sequences of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
What Type of polynucleotide acting as messenger?
D
Is nucleic acid a long chain of simple sugars?
DNA and RNA are both forms of polynucleotide. This means that they are long molecules made up of many individual monomer units. The basic monomer unit of a polynucleotide is a nucleotide. The three primary components of a nucleotide are the phosphate group, the pentose sugar and the nitrogenous base. In DNA, the pentose sugar present in the nucleotides is deoxyribose. In RNA, the pentose sugar present in the nucleotides is ribose. In DNA, the four bases present are adenine, thymine, guanine and cytosine. In RNA, the base uracil replaces the base thymine. DNA is also a double-stranded polynucleotide, whereas RNA is a single-stranded polynucleotide.
