Kendrick Lamar

Kendrick Lamar Duckworth (born June 17, 1987) is an American rapper from Compton, California. Lamar embarked on his musical career as a teenager under the moniker K-Dot, released a mixtape which garnered local attention and led to his signing with Carson-based independent record label Top Dawg Entertainment (TDE). Lamar began to gain major recognition in 2010 after his first retail release, Overly Dedicated. The following year, he released Section.80, his first independent album, exclusively through iTunes. The album included Lamar's debut single, "HiiiPoWeR". By that time, Lamar had amassed a large internet following and had already worked with several prominent artists in the hip hop industry, including The Game, Snoop Dogg, and Busta Rhymes.

Lamar secured a recording contract with Aftermath and Interscope Records in 2012. His major-label debut album, good kid, m.A.A.d city, was released in October 2012 to universal acclaim. The record contained the top 40 singles "Swimming Pools (Drank)", "Bitch, Don't Kill My Vibe", and "Poetic Justice". Upon its release, the album debuted at number two on the U.S. Billboard 200 chart and was later certified platinum by the Recording Industry Association of America (RIAA). In early 2013, MTV named Lamar the No. 1 "Hottest MC in the Game" on their annual list.

DNA

Deoxyribonucleic acid (ⁱ/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/;DNA) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T, and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 10³⁷, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.
