Musically, the album was influenced by electronic dance music, and other genres, with elements like funk carioca and dubstep. DNA was produced by Mr. Jam and Dennonyx. The first information about DNA appeared in 2010 in an interview with radio Transamerica, revealing that the album would be entirely in English. The recording sessions started in São Paulo, Brazil and it was finished and mastered in New York, in the Sterling Sound Studios.

On November 13, 2010 Wanessa revealed in an interview for the radio Transamerica her new album was recorded in early 2011, with an electropop dance sound, and would include the four songs from her EP "Party Line", "Stuck on Repeat", "Falling For U" and "Worth It". On January 8, 2011, against the comments that it would launch an international album, Wanessa, in an interview for Rolling Stone Brazil said that, her plans were to set herself in Brazil. In the same interview, the singer said she would be entering the studio to release her album at the end of March, which would be entirely in English and focusing on pop and a remix of the single "Stuck On Repeat", produced by American DJ Dave Aude, known by his work with Lindsay Lohan, Hilary Duff and Lady Gaga.

On March 14, the singer participated in the program Combo - Fala + Joga, and revealed that the album would be postponed to June 2011 and that it would not only include electropop songs, but also include two calm and romantic songs, devoted to gender in her most successful single, "Não Resisto a Nós Dois". In another interview, Wanessa said that her new album was produced by Mr. Jam, known for working with the singer in the tracks "Falling For U" and "Stuck On Repeat".DNA would be composed of 16 tracks.

On July 17, it was confirmed by the singer's Twitter that the album would be released on July 28, 2011, eight days behind the previously announced release. On July 18, the cover and back cover and the official track list of the album were released, bringing 14 songs, two less than expected, and excluding "Party Line", the only track in the 2010 track list that had been composed by Wanessa (however, two other compositions by Wanessa entered the track list, "It's Over" and "Blind Faith"). Five days before its scheduled release, DNA leaked in full.
