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.

Transcribed Image Text:Alpha helices are a type of secondary structure in proteins. Recall that there are 3.6 residues per turn
in an a-helix and that turn spans a distance of 5.4 A (i.e. its 'pitch' is 5.4 Å).
Beta strands are another type of secondary structure found in proteins. Recall that the distance
between residues that adopt the 3-strand conformation is about 3.5 A.
For a peptide that is 72 residues long, fill in the following blanks:
• The total length of the peptide if all of the Amino acids adopt the 3-strand conformation is
Å long.
. The total length of the peptide if all of the amino acids adopt the a-helix conformation is
Å long.
• The 3-strand peptide is
times longer than the a-helical peptide.
