<span><span>#1) What would be the pros and cons of using Linnean and modern classification system?
</span><span>Answer: The pros of using the Linnean classification system is that it conveys a very detailed information about the species and the closest relatives of living things. It helps scientists to understand the complex relationships. A con is that it takes a very large amount of information and time for this system to develop.

Answer:
substitution - a base was changed
Explanation:
The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.
An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)
A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)
It is false. The transcription in eukaryotes is affected by regulatory proteins that sticks to certain DNA arrangements that are sometimes found thousands of pairs away from the promoter. The regulatory arrangements can be found downstream, upstream, or even inside the segment of the converted DNA. A few regulatory arrangements probably exist for a given gene. It is interesting that the transcriptional activators and repressors operates by sticking to DNA at far areas from the promoter. The folding of DNA enables the approximation of remote areas of the double helix to assist in the positioning of the activator protein, affixed to the enhancer, near the initiation system and the promoter.
