Why does a detetion mutation usually cause more defect during protein synthesis than point mutation?
Mutation usually causes the entire base sequence to defect. This usually happens during the protein synthesis.
How might protein synthesis execute differently if a mutation occurs?
A mutation can alter the sequence of DNA, causing changes in the mRNA produced during transcription. This can result in the insertion, deletion, or substitution of amino acids in the protein sequence during translation. These changes can impact the structure and function of the protein, potentially leading to a non-functional or altered protein being produced.
What is the difference between a point mutation and an insertion and deletion?
Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur. If a deletion mutation occurs then the code for the protein is disrupted and the protein product is probably going to be useless to the body and may even cause a disease.
What is truncation mutation?
Truncation mutation is a type of mutation that results in the premature termination of the protein synthesis process. This leads to the production of a truncated or incomplete protein which may be nonfunctional. Truncation mutations can have serious consequences on the structure and function of the protein.
What is a frameshift in DNA?
Referring to the frameshift mutation in genes, frameshift is where number of nucleotides inserted or deleted is not a multiple of three, resulting in every codon after the point of insertion or deletion is read incorrectly during translation.
Is the deletion mutation dominant or recessive?
A deletion mutation can be dominant or recessive, depending on the specific gene affected and the consequences of the deletion on the protein encoded by that gene. In general, the impact of a deletion mutation on an individual's phenotype will determine whether it is dominant or recessive.

Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Deletion mutations can affect the entire base sequence.
Why does an insertion mutation usually cause defects during protein synthesis than a point mutation?
Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.
Is information lost during a deletion mutation?
Yes. The genetic code after the deletion is essentially nonsense when it comes to building the protein. The amino acid sequence after the deletion will be completely altered, resulting in a poorly functioning or completely nonfunctioning protein, depending on where the deletion occurs.
A random change in the base sequence of DNA resulting in the production of a defective protein is called?
A random change in the base sequence of DNA resulting in the production of a defective protein is called a mutation. Mutations can lead to changes in the amino acid sequence of a protein, affecting its structure and function.
What type of mutation when a nucleotide is dropped from a DNA sequence?
A deletion mutation occurs when a nucleotide is dropped from a DNA sequence. This can cause a shift in the reading frame, leading to a non-functional protein being produced.
What mutation can change every amino acid that follows the point of mutation?
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
What is the difference between a point mutation and an insertion and deletion?
Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur.

This leads to the production of a truncated or incomplete protein which may be nonfunctional. Truncation mutations can have serious consequences on the structure and function of the protein.
What type of mutation could result in a much shorter protein than the original gene product?
A frameshift mutation, such as an insertion or deletion of nucleotides, can cause a shift in the reading frame of a gene during translation, leading to a premature stop codon. This results in a truncated protein that is much shorter than the original gene product.
