To the best of my knowledge, there are only two and they would be ribose and deoxyribose
hope this helps if not just let me know
Answer:
A mutation in the DNA sequence of the gene for brown fur
Explanation:
The mutations are capable of changing the encoded protein product, in this case the gene that encodes for the fur color pigment. This mutation may have occurred during mitosis or meiosis divisions.
If it is a spontaneous mutation that occurred in the germinal line (meiosis) and confers an adaptive advantage, it will increase their frequency in the population.
It is B. Because you cannot give internal fertilization/ live birth inside.
MRNA carries a transcript of the needed amino acids to tRNA and then to the rRNA ribosomal component.
