Herein, what are the two strands of DNA called?
The two DNA strands are also known as polynucleotides as they are composed of simpler monomeric units called nucleotides. The two strands of DNA run in opposite directions to each other and are thus antiparallel. Attached to each sugar is one of four types of nucleobases (informally, bases).
Additionally, what does each DNA strand represent? Each DNA strand of a progenitor cell serves as a template for the synthesis of a new complementary polynucleotide chain that is identical to that of the original cell. This process is known as DNA replication.
Furthermore, what is the complementary strand of DNA?
In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
How many strands of DNA are there?
Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA tied by hydrogen-bonds to each other making the classic DNA double helix (double-stranded DNA). So, in total there are 46*2=92 strands of DNA in each diploid human cell!
