positive regulation of isotype switching to IgA isotypes

Any process that activates or increases the rate of isotype switching to IgA isotypes.

The process by which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating unpaired template strands for DNA replication.

Catalysis of the hydrolysis of ester linkages within deoxyribonucleic acid by creating internal breaks.

The formation from simpler components of pyrimidine ribonucleoside triphosphate, a glycosamine consisting of a pyrimidine base linked to a ribose sugar esterified with triphosphate on its glycose moiety.

DNA replication, synthesis of RNA primer

The generation, by DNA polymerase alpha, of an RNA primer followed by a short segment of DNA on the lagging strand of the replicating DNA.

Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks.

Catalysis of the endonucleolytic cleavage of RNA to 3'-phosphomononucleotides and 3'-phosphooligonucleotides ending in C-P or U-P with 2',3'-cyclic phosphate intermediates.

Catalysis of the endonucleolytic cleavage of RNA in RNA-DNA hybrids to 5'-phosphomonoesters.

Catalysis of the endonucleolytic cleavage of RNA-DNA hybrids to 5'-phosphomonoesters.

Catalysis of the endonucleolytic cleavage of RNA to 5'-phosphomonoesters; cleaves multimeric tRNA precursor at the spacer region; also involved in processing of precursor rRNA, hnRNA and early T7-mRNA; also cleaves double-stranded DNA.

Catalysis of the endonucleolytic cleavage of RNA, removing 5' extra nucleotides from tRNA precursor.

Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' or 5' end.

Catalysis of the sequential hydrolytic removal of 5'-nucleotides from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.

Catalysis of the reaction: L-tryptophan + tetrahydropteridine + O2 = 5-hydroxy-L-tryptophan + dihydrobiopterin + H2O.

The chemical reactions involving DNA, deoxyribonucleic acid, one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides.
