The differences are as follows:
Mismatch repair
DNA polymerase is the enzyme that is responsible for DNA replication. As it copies the the DNA, it can make mistakes. So, when the DNA is copied, mismatch repair proofreads it and makes sure that the nitrogenous bases are correct. If they aren't, then it will take out only the base. However, if the mismatch repair is not functioning, then humans can get some form of cancer.
Excision repair
This mechanism is caused by UV rays or some sort of harmful chemical. Excision repair fixes what portion may have been destroyed by these mutagens. It takes the entire strand and replaces it with a new one. However, if this mechanism doesn't work, then forms of skin cancers arise.

What is the difference between DNA proofreading and mismatch repair?
DNA proofreading occurs during DNA replication and involves the DNA polymerase enzyme checking for errors in base pairing as it synthesizes a new DNA strand. Mismatch repair occurs after DNA replication and involves specialized enzymes that recognize and remove mismatched base pairs that were not corrected during proofreading. In other words, proofreading happens during synthesis, while mismatch repair occurs after synthesis is complete.
What is the difference between an allele and a SNP?
An allele is a specific form of a gene, while a SNP (Single Nucleotide Polymorphism) is a variation in a single nucleotide within a gene. In other words, alleles are different versions of a gene, while SNPs are specific points of genetic variation within a gene.
What are the differences between the 5' end and the 3' end of a nucleotide?
The 5' end of a nucleotide has a phosphate group attached to the 5th carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3rd carbon. This structural difference affects how nucleotides are linked together in DNA and RNA strands.
How can one determine whether a nucleotide is DNA or RNA?
One can determine whether a nucleotide is DNA or RNA by looking at the sugar molecule it contains. DNA nucleotides have deoxyribose sugar, while RNA nucleotides have ribose sugar. This difference in sugar molecules helps distinguish between the two types of nucleotides.
What is the difference between a base and a nucleotide?
A nucleotide is the sugar (in DNA is a deoxyribose in RNA it's ribose), phosphate group and 1 base. A base pair is the "rung in the ladder" for example in DNA it could be adenine + thymine or guanine + cytosine. In RNA the thymine is replaced by uracil
What is the primary difference between the excision codes found in the musculoskeletal system subsection and the excision codes found in the integumentary system subsection?
the primary difference is extent
What is the difference between an incision and excision of lymph nodes?
The difference between incision and excision of lymph nodes is very simple. The incision of a lymph node is when the biopsy only takes part of the lymph node during surgery. The excision of the lymph node is when the whole lymph node is removed.
What the difference between total lobectomy and hemithyroidectomy?
Hemithyrodectomy is Lobectomy + isthmus excision
What is the difference between incision and excision?
An incision is the deliberate cut that is performed into the body tissues to gain access to deeper structures whereas excision is the removal of tissues as therapeutic approach.
What is the primary difference between the ecision codes found in musculoskeletal system and the excision codes found in integumentary system subsection?
The primary difference is extent.
What is the difference between a variation and a mutation?
mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species.
What is the mismatch between the knowledge and skills acquire by the students and the industry needs.?
The disparity between training and the needs of a job is called skills mismatch or education mismatch and is expressed as a lower employability.
What is the mismatch between the knowledge and skills acquired by the students and the needs of industry?
The disparity between training and the needs of a job is called skills mismatch or education mismatch and is expressed as a lower employability.
What is the difference between nucleotide deletion and nucleotide insertion?
Here's a sample nucleotide sequence:AATUGCIf there was a nucleotide deletion (let's say the "G" gets deleted), the sequence would become:AATUCIf there was a nucleotide addition/insertion (let's say a "G" was added between "T' and "U"), the sequence would become:AATGUGCThe difference is that a deletion makes the DNA shorter and an insertion makes it longer.
What is the difference between 5' and 3' end of a DNA molecule?
The 5' end starts with a phosphate as the nucleotide and the 3' end starts with deoxiribose, or the sugar as the nucleotide.
What are modified enzyme?
DNA Modifying EnzymesEukaryotic and prokaryotic cells possess multiple mechanisms to repair DNA and control damage to their genomes. These include base excision repair (BER) and nucleotide excision repair (NER) that excise and replace damaged nucleotide bases and helix-distorting lesions, respectively. Many of the enzymes involved in NER are also active in transcription-coupled repair (TCR) processes. In addition, mismatch repair (MMR) enzymes act to replace mismatched nucleotides and repair insertion/deletion loops. Furthermore, there are two types of double-stranded DNA break repair, homologous recombination (HR) and non-homologous end-joining (NHEJ).Base excision repair proteins correct DNA lesions and ensure that mutations are not propagated. The process of base excision repair is achieved via specific and sequential enzyme activity. Damaged bases are first identified and removed by DNA glycosylases/AP lyases, which break beta-N glycosidic bonds to create an abasic (AP) DNA site. Depending on the initial events of base removal, repair proceeds through either the short patch (1 nucleotide) or long patch (2-10 nucleotides) repair pathways. This involves the AP site being recognized by endonuclease enzymes which nick the damaged DNA, and recruit DNA polymerases to fill the gap in the DNA. Base excision repair is completed by DNA ligase sealing the nick between the two strands.Nucleotide excision is an additional DNA repair mechanism which removes nucleotides that have been damaged by chemicals or ultraviolet radiation. Nucleotide excision generates a short single-stranded DNA gap, which is subsequently used as a template by DNA polymerase. In addition to base and nucleotide excision repair molecules, mismatch repair (MMR) enzymes act to replace mismatched nucleotides and repair insertion/deletion loops. Genotoxic stress can introduce DNA double-strand breaks (DSBs), which are repaired by either homologous recombination or non-homologous end-joining. The Mre11/Rad50/Nbs1 (MRN) complex, along with members of the Rad51 family of proteins, are involved in double-strand break repair during homologous recombination. R&D Systems offers quality DNA enzyme products which include DNA glycosidases, endonucleases, polymerases, ligases, and more.
What is structural unemployement?
Structural unemployment is the result of a mismatch between the skills of the work force and those needed by employers.
