How Do You Spell DNA HELICASE?

Pronunciation: [dˌiːˌɛnˈe͡ɪ hˈɛlɪkˌe͡ɪs] (IPA)

DNA helicase is an enzyme that unwinds the double-stranded DNA molecules during DNA replication. The spelling of this word is dɛˈɛnˈeɪ ˈhɛlɪkeɪs, where the "d" and "n" are pronounced separately to represent the individual letters. The "ɛ" sound in the beginning and middle of "hel" is indicated by ˈɛ. The "k" sound in "helikase" is represented by "k" as opposed to "c" to indicate a hard "k" sound. The final "s" sound in "helicase" is pronounced with a "z" sound due to the added "e."

DNA HELICASE Meaning and Definition

1. DNA helicase is an essential enzyme that plays a crucial role in DNA replication and repair processes. It belongs to the class of enzymes known as helicases, which are responsible for unwinding the double-stranded DNA molecule. Specifically, DNA helicase functions by breaking the hydrogen bonds that hold the two strands of DNA together, allowing for the separation of the two strands and the formation of the replication fork.

   The DNA helicase enzyme operates during DNA replication by untwisting the double helix structure and moving along the DNA molecule in a direction known as a 5' to 3' polarity. As it moves, it separates the two strands, enabling the DNA polymerase enzyme to synthesize a new complementary strand on each template.

   Furthermore, DNA helicase also participates in DNA repair mechanisms such as nucleotide excision repair, homologous recombination, and DNA recombination, where it unwinds DNA to permit the repair or recombination process.

   Moreover, DNA helicase acts as a critical factor in DNA transcription, which involves the synthesis of messenger RNA from a DNA template. In this process, the helicase unwinds the DNA molecule to allow the RNA polymerase enzyme to access the DNA strand and synthesize the complementary RNA sequence.

   In summary, DNA helicase is an indispensable enzyme that plays a central role in DNA replication, repair, and transcription by unwinding the double helix structure, facilitating the necessary molecular processes to occur accurately and efficiently within the cell.

Etymology of DNA HELICASE

The word "DNA helicase" has its etymology rooted in two components: "DNA" and "helicase".

1. DNA: DNA stands for "deoxyribonucleic acid", a molecule that carries the genetic instructions used in the development and functioning of all known living organisms. The term "DNA" was first coined in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty, who discovered that DNA is responsible for carrying genetic information.

2. Helicase: The term "helicase" derives from the Greek word "helix", meaning spiral or coil. In molecular biology, helicases are enzymes that are responsible for unwinding and separating the double-stranded DNA helix during processes such as DNA replication, transcription, and repair. The term "helicase" itself was coined by Albert Y. C. Linn and Rufus K.

Plural form of DNA HELICASE is DNA HELICASES
