Web3. what errors can occur during mitosis and what are the implication to the living organisms? Answer: Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. WebJul 29, 2008 · When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred. UV light can cause mutations, as the DNA molecules are good absorbers of UV. Two of the bases in DNA (Cytosine and Thymine) are the most vulnerable, and when this happens, they may pair with each other or themselves and …

Mutations, variations in the nucleotide sequence of a genome, can also occur … WebAug 24, 2024 · Variation can also result due to errors that take place during the process of DNA replication. DNA replication is an essential part of biological inheritance and occurs in all living organisms. DNA is a highly stable molecule, and it replicates with high accuracy; changes in DNA structures and replication errors do occur.

Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline … WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.
