Deletions and substitutions are types of mutations Which type is more likely to cause mistranslations of proteins?

Deletions, because they shift the reading frame and cause downstream amino acids to be changed.

How might a point mutation in a gene affect the reasulting protein?
point mutations include substitutions insertions and deletions of a single nuceotide in DNA. CONSIDER: insertions and deletions have a greater effect on proteins that do substiutions because insertions and deletions affect every amino acid that is specified by the nucleotides that follow the point of mutation CONSIDER: a substitution affects a single amino acid a change in more than one amino acid is more likely to alter the ability of the protein to function narmally than is a change in a single amino acid CONSIDER: follow me on twitter @Rocco_Gone_Ham
Is point mutation lethal?
No. Point mutations, or those resulting from a change in one or a few nucleotides at a single location in a DNA sequence. There are two types of point mutations: base substitutions and frameshift mutations. Not all mutations are in these coding sequences but if they are, then the result can be different or non-functioning proteins. They are considered to be neutral, beneficial or harmful. Two harmful point mutations are sickle cell anemia and polycystic kidney disease.
Why do mutations in gene affect traits?
Genes produce proteins that cause traits.
How can DNA-level mutations affect the structure of proteins?
DNA is formed out of proteins, mutations can cause the bonds between the chains to loosen or not form at all. It may also cause additonal bonds forming and changet the order of amino acids involved in the chain.
Are mutated prions shaped like a rod?
Normal Prions are shaped like a coil. Mutations in genes that code for these proteins occur, causing the proteins to be misfolded.

Which is more harmful frameshift mutation or point mutation?
point mutations include substitutions insertions and deletions of single nucleotides in DNA. insertions and deletions have a greater effect on proteins than do substitutions because insertions and deletions affect every amino acid that is specified by the nucleotides that follow the point mutation. in contrast a substitution affects a single amino acid. a change in more than one amino acid is more than likely to alter the ability of the protein to function normally than is a change in a single amino acid

Why does Mutations lead to the production of aberrant proteins?
'cause.
What is the significance of mutations to living things?
Many, if not most, mutations are neutral, meaning that they have little or no effect on the expression of genes or the function of the proteins for which they code.
Do mutations in genes affect traits?
Genes produce proteins that cause traits.

What happen when there are mistakes made during protein synthesis?
The ribosomes are the " workbench " of protein synthesis with the rough ER accepting some polypeptide chains from the ribosomes studding it into it's lumen for modification. Then the modified proteins are shipped to the Golgi for further modification and shipment to wherever they are needed.
What is the mutated gene of the Charcot-Marie-Tooth disease?
CMT is caused by mutations in genes that produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. Although different proteins are abnormal in different forms of CMT disease, all of the mutations affect the normal function of the peripheral nerves. The gene mutations in CMT disease are usually inherited.
What is the malfunctioning organelle associated with Pearson syndrome?
Pearson marrow-pancreas syndrome is caused by single, large deletions of mtDNA (the DNA found in the mitochondria), which can range from 1,000 to 10,000 DNA building blocks (nucleotides). The mtDNA deletions involved in Pearson marrow-pancreas syndrome result in the loss of genes that provide instructions for proteins involved in oxidative phosphorylation.
