Conversation so far:
when constructing an dna molecule what is important when determining the orientation of each strand
The two strands of DNA run in opposite directions to each other and are thus antiparallel.
What other name do the DNA strands go by
The two DNA strands are also known as polynucleotides as they are composed of simpler monomeric units called nucleotides.
What are the nucleotides made of
Each nucleotide is composed of one of four nitrogen containing nucleobases, a sugar called deoxyribose, and a phosphate group
How are the nucleotides joined
The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next
