The correct answer is: c. The DNA strand begins to unwind, separating the two strands.
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
By age of 6, the average child has a vocabulary of around 14,000 words. Vocabulary development can be relatively variable among children of the same ages. Children typically speak their first word somewhere around 12 months. At 18 months, they may use around 50 words or lower and there is an increase in the number of words with age.
The answer is binary fission
ANSWER: Primary succession
Enzymes are a substance produced by a living organism, which acts as a catalyst to bring out the specific biochemical reactions they are biochemical reactions... I hope this helps
