1) compound mutagens can go about as base analogs
Analogs are perceived by DNA polymerase and consolidated into DNA set up of nucleotides and after that reason change by base-matching in a way that varies from the undifferentiated from nucleotide. For instance, 5-BrdU can be consolidated inverse An amid replication and after that combine as a C amid the following round of replication, making a TA CG change.
2) substance mutagens can synthetically adjust base.
Compound adjustment of bases changes their base-blending properties to such an extent that an altered purine will base-match with the wrong pyrimidine and the other way around. For instance, EMS is an alkylating operator that proselytes guanine to O6-methylguanine, which base-sets with T to make a GC to AT progress
<span>Synaptic cleft or the terminal buttons that transmits neurotransmitters to the next neuron, received by its dendrites and is relayed now throughout the system until it reaches the brain.
The messages must travel the distance of the nerves to the brain which are processed and made decisions, from the distance of the nerves from the sense organs, then travel back to the muscles that need to respond through the nerves.<span> </span></span>
Answer:Genetic information are transferred from nucleus to cytoplasm of cell through RNA. In eukaryotic cells, once precursor mRNA (pre-mRNA) has been transcribed from DNA, it is processed to mature mRNA. This removes its introns, non-coding sections, of the pre-mRNA.

hope that helps
<span>The
answer is a fecal occult blood test (FOBT) that checks for hidden (occult)
blood in the stool (feces) by use of a microscope. The major disadvantage is that it is not very
accurate because it is not a 100% reliable as an indicator of colorectal
cancer. Sigmoidoscopy is often undertaken following a positive FOBT</span>
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
