<span>Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.</span>
Each human has 2 alleles and are called diploid organisms. We receive 1 allele from each biological parent.
Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting
