By convention, the sequence of bases in a nucleic acid is always written in which direction? a) 3/→ 51 О b) 51→ 31 c) amino to carboxyl d) carboxyl to amino
Coding Strand of DNA
When pointing to DNA transcription, the coding strand is found to be the DNA strand whose base sequence is indistinguishable from the base sequence of the RNA transcript developed. It is this strand that comprises the codons, while the non-coding strand comprises the anti-codons.
Nucleotide
Both DNA and RNA are composed of organic molecules known as nucleotides. Hence, nucleotides are known as the basic building blocks of nucleic acids. These substances play a role in various processes such as cell signalling, enzyme reactions, metabolism, and so on.
Structure of Cytosine
Cytosine is among the five primary nitrogenous bases of which DNA and RNA and are being used in storage and transportation of genetic makeup within a cell. Adenine, guanine, thymine as well as uracil are the remaining four nucleobases.

![Why is DNA said to be antiparallel?
a) Each strand of the double helix is made up of a sugar phosphate backbone
which runs in the 5' to 3' direction.
b) DNA has polarity such that one strand runs in the 3' to 5' direction and the
other in the 5' to 3' direction.
c) The two strands of DNA are joined together via complementary base pairing
such that AT run in the 3'to 5' direction and CG run in the 5' to 3' direction.
d) The DNA strands twist into a helix conformation once the bases have joined
to form major and minor grooves.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F52052328-5a34-4195-86aa-03a6e2c9ba62%2F40e336bf-11e2-4005-8fe8-35ffae656b1c%2Fppapwqg_processed.png&w=3840&q=75)
