Does every mutation that causes a nucleotide base change also cause a change in the amino acid sequence of a protein? Explain.How would a mutation in the seventh codon of normal hemoglobin, changing it from CTC to ACT, affect the protein being synthesized?
How does DNA mutation affect protein structure? What is the structure of DNA determined by? What are the main structural features of B-DNA? How do the bases bond together in DNA? How does DNA encode the protein structure? How does DNA structure determine the specific shape of enzymes?

The calculated free energy barriers of the methyl transfers suggest that the Y276F mutation decreases the catalytic activity of the methyl transfer, while the Y357F mutation does not change the catalytic activity of the methyl transfer. The reactant complex conformations generated in the QM/MM MD...
However, the H38S mutation that has the largest effect on C179 resistance in our experiments does not introduce a glycosylation motif, showing that there are also other ways to escape anti-stalk antibodies at this site. Interestingly, group 1 HA subtypes that are susceptible to C179 tend to ...
Silent Mutation:Although a change in the DNA sequence occurs, this type of mutation does not change theproteinthat is to be produced. This is because multiple genetic codons can encode for the same amino acid.Amino acidsare coded for by three-nucleotide sets called codons. For example, the ...
Ca2+ calmodulin complex does a master role in subcellular variable effects as enzyme activation, growth signaling, transcription factors which consequently control the cellular behavior [51], [52], [53]. Three genes were identified to encode Ca+2 calmodulin protein, CALM1, CALM2, and CALM3 and...
Protein coding features can emerge de novo in non coding transcripts, resulting in emergence of new protein coding genes. Studies across many species show that a large fraction of evolutionarily novel non-coding RNAs have an antisense overlap with protei
A form of chronic inflammatory bowel disease that can affect the entire gastrointestinal tract but is most common in the colon and terminal ileum. It is characterized by transmural inflammation, strictures and granuloma formation, and is thought to result from an abnormal T cell-mediated immune resp...
How would protein synthesis execute differently if there is a mutation? How would a point mutation in an intron affect a protein? Explain trasduction in relation to bacterial gene transfer. Explain why all mutations are not necessarily harmful? Does changing the sequences of nucleotide...
