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.
Answer:
Make sure the lights are off if you are the last to leave the classroom, take shorter showers, and consume less meat and dairy products are all good ways you can reduce your personal footprint. Taking the time to get involved in conservation efforts in your area is a great way you can help fight climate change.
Answer:
The answer is A) Meteors
Explanation:
A meteor is an asteroid or other small body of matter from outer space that heats up and burns while in the atmosphere.
The coral provides the algae with a protected safe environment (a home) and compounds they need for photosynthesis. The algae in return, produce oxygen and help the coral to remove wastes. Most importantly, zooxanthellae supply the coral with glucose, glycerol, and amino acids, which are the products of photosynthesis.
Answer:
The phenotype of the rabbit is the absence of fur colour and the genotype is the alleles rr.
Explanation:
The genotype can be described as the genes which are present in an organism. Genes are made up of alleles. As the rabbit in the question carries the alleles, rr, hence it is the genotype of the white albino rabbit.
The phenotype can be described as the physical appearance that results from the particular genes present in an organism. As the white albino rabbit carries the alleles,rr, due to which it doesn't have fur, hence no fur is the phenotype of it.
