Question

In what form is DNA typically represented when discussing its sequence?

a) As a sequence of nucleotides
b) In the double-helix shape of the condensed chromosome
c) As a pattern of phosphates and sugars
d) In the ratio of adenine to thymine

Answer 1

DNA is typically represented as a sequence of nucleotides, which are the building blocks of genetic information encoded in the DNA sequence.

Step-by-step explanation:

When discussing its sequence, DNA is typically represented as a sequence of nucleotides. Each nucleotide is composed of three parts: a sugar (deoxyribose), a phosphate group, and a nitrogen-containing base (adenine, guanine, cytosine, or thymine), and the sequence of these bases along the DNA strand encodes genetic information. The double-helix structure of DNA consists of two polynucleotide chains that are complementary and antiparallel, meaning that they run in opposite directions. During the process of DNA replication, each daughter cell receives a copy of the DNA, ensuring that the genetic information is faithfully transmitted.
