- A mutation in gene changes a base pair from at to gc this change caused gene to encode truncated protein that is nonfunctional so an organism cannot produce offprince describe this mutationIn nature, the vast majority of individuals within a species have unique genetic codes. In the last few decades, human geneticists have discovered ways to artificially duplicate a genetic code. Two organisms with identical genetic codes might be the result ofA. CloningB. MutationC. CoevolutionFor insertion mutation ( ecoli bacteria) and growth mutation (cactus), do you think thismutations will be for, or against their evolution, why? use cactus and e coli bacteria to make it easier for me.
- Drag each term to its correct location in this concept map about mutations.. SCIENTIFIC INQUIRY The scientists mapping the SNPs inthe human genome noticed that groups of SNPs tended to beinherited together, in blocks known as haplotypes, ranging inlength from 5,000 to 200,000 base pairs. There are as few as fouror five commonly occurring combinations of SNPs per haplotype.Integrating what you’ve learned throughout this chapter and thisunit, propose an explanation for this observationFill the blank New genes can arise during evolution through: (i) exonshuffling, which can alter the domain structure of proteins;(ii) duplication and divergence that generates gene families;and (iii)_______ mutations in intergenic DNA sequences.
