1. These four factors can effect ways evolution occur:
<span>1.) Mutation
2.) selection
3.) Gene Flow
4.) Genetic Drift
2. </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.
In population genetics, gene flow is the transfer of alleles or genes from one population to another.
<span>Genetic drift is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>
Hello!
You can choose the difference!
Bacterial cell is 0.2 to 2 um in size, while an animal cell is 10-100 um in size
Bacterial cells are made up of murein, while animal cells don't have a cell wall
Bacterial cells dont posses a nucleus, while animal cells do posses one.
There are more differences, but these are the biggest.
<span>Hope this helped you!</span>
So the cells can react to the changes, and so that specialized cells can perform certain functions
I found the whole exercise on the internet. Here are the events mentioned:
"-<span>Mismatched bases in the heteroduplex trigger mismatch repair.
-Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
-A heteroduplex is formed between </span>R (wild-type) and r (mutant) alleles.
-Mismatched bases are excised from the R (wild-type) allele.
-The wild-type R allele is converted to the mutant r allele."
The correct order is:
1. Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
2. A heteroduplex is formed between R (wild-type) and r (mutant) alleles.
3. Mismatched bases in the heteroduplex trigger mismatch repair.
4. Mismatched bases are excised from the R (wild-type) allele.
5. The wild-type R allele is converted to the mutant r allele.
