Chapter 12/ Lesson 4 216K What is a frameshift mutation in DNA coding? Review the types of mutations, and find out what causes a frameshift mutation and some examples of their effects. Related to this Question What does a mutation in the DNA do to the polypeptide?
During translation, a three-nucleotide sequence of mRNA called a codon specifies whichshould be linked up next. It is important to maintain the integrity of codons so thecan link the correct amino acids together and form the correct protein. When a frameshift mutation occurs, there is an error...
Proflavinis an acridine dye that intercalates itself between base pairs of the DNA chain thereby causing loss or gain of a single nucleotide. The gene mutation alters the base sequence of the whole genetic frame from the point of mutation called frameshift mutation. What is the effect of fra...

(Smith et al.2017). Genomic mutation libraries have already been developed for crops such as rice and tomato (Lu et al.2017; Jacobs et al.2017). However, the use of high-throughput screening in plant research is still in its nascent stages. The development of a CRISPR mutant library ...
Frameshift mutations can also induce inactivation of beta2-microglobulin leading to HLA class I downregulation[32,33] though the association between HLA class I downregulation and MSI is still controversial. Altogether, CRC associated with MSI could lead to a more intense immune response, but...
The most frequent disease-causing mutation of the CLN3 gene is a 1 kb deletion, which removes exons 7 and 8 and creates a premature stop codon. This mutation results in a substantial decrease in mRNA expression and stability, so most likely the mutant, truncated protein is not expressed at...
It also found that these noncoding RNA are transcribed by a class of satellite DNA, although they do not produce proteins, their regulatory role is closely related to the growth of tumor [25, 26]. Mutational characteristics in various cancers An analysis based on TCGA data shows that there ...
