Document Summary

The science of biology: chapter 4 -nucleic acids & the origin of life. Nucleotides are the building blocks of nucleic acids. Nucleic acids are polymers composed of monomers called nucleotides. Consists of three components: a nitrogen-containing . Nucleotides pentose sugar, and one to three phosphate groups. The bases of nucleic acids take one of 2 chemical forms. New nucleotide are added to an existing chain one at a time. the pentose sugar in the last nucleotide of the existing chain and the phosphate on the new nucleotide undergo a condensation reaction, resulting in this bond. Include rna molecules that function as primers" to begin the duplication of dna; rna molecule that regulate the expression of genes; and synthetic dna molecule used for amplifying and analyzing other, longer nucleotide sequences. Polynucleotides , more commonly referred to as nucleic acids, include. Dna and most rna. they can be very long. Dna- thymine and adenine always pair (t-a), and cytosine and guanine.
