The correct answer is: b. It is free to bind to another promoter and begin transcription
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.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
Because in simple molecules the intermolecular forces are a Coavlent bond and is formed between carbon and ionic compounds
The skeletal muscle is used, so A.
The image was missing from the question.
The correct answer is genetic drift.
As you can see, the image presents a large amount of fish being caught by a fishing net. The genetic drift is one of the four mechanisms of evolution and it changes the frequencies of alleles in the population randomly.
In our case, the fishes caught by the fishing net are not going to reproduce and pass on their genetic material, therefore changing the genetic structure of the next generation. This event is solely random ( there is no mechanism of selection which individual fish is going to be caught).
