If an organism has a mutation, that helps it survive, it will breed and this mutation will keep in the gene pool. Out of all listed choices, the only mutation that will help an organism survive is c). The better a rabbit can hide from predators, the longer it will survive and the more will breed
Answer:
The correct answer is B) Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane.
Explanation:
The transcription process in eukaryotes takes place in the nucleus of the cell and after transcription post-transcriptional modification also takes place in the nucleus which is necessary to guide the mRNA out of the nucleus.
First, the process of transcription takes place in which DNA is transcribed to mRNA by an enzyme called RNA polymerase. After transcription post-transcriptional modifications takes place in the given order.
1. Capping: In capping process 7-methylguanosine is added by capping enzyme at 5' end of mRNA.
2. Polyadenylation: In polyadenylation, many poly-A residues are added at the 3' end of the mRNA called the poly-A tail.
3. Intron splicing: Introns are the non-coding sequence present in mRNA which are spliced out of mRNA and all exons are joined together.
After these post-transcriptional process, the mature mRNA is transported out of the nucleus through the nuclear membrane.
Answer:
Your answer is A). True.
Explanation:
The integumentary system is made up of several organs and structures including the skin, hair, nails, glands, and nerves. The primary function of the integumentary system is to protect the inside of the body from elements in the environment, like bacteria, pollution, and UV rays from the sun.
