Explanation:
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
Approximately eighty seven percent of lung cancer deaths are caused by smoking.
Answer:
Step 1: Initiation - begins at the region of the DNA called the Promoter
Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.
Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.
Explanation:
Transcription is the process in which RNA molecules are synthesized from the information stored in the DNA found in the nucleus. The region of the DNA that codes for genes is transcribed, or copied, into messenger RNA, known as mRNA, which then leaves the nucleus and enters into the cytoplasm where the information it carries is used to synthesize proteins.
Transcription occurs in three steps which are summarized below:
Step 1: Initiation - begins at the region of the DNA called the Promoter
Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.
Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.
