WebMar 27, 2024 · In its inactive form, PKA holoenzyme is a heterotetramer composed of two regulatory (R) and two catalytic (C) subunits. 2-4 Four types of R subunits (RIα, RIβ, RIIα, and RIIβ) and three C subunits (Cα, Cβ, and Cγ) have been described 5 with RIα, RIIα and Cα being the major isoforms expressed in the heart 6 and encoded by distinct genes. The IUPAC has designated the symbols for nucleotides. Apart from the five (A, G, C, T/U) bases, often degenerate bases are used especially for designing PCR primers. These nucleotide codes are listed here. Some primer sequences may also include the character "I", which codes for the non-standard nucleotide … See more Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate.
