Why do a frame shift mutation usually cause more defects during protein synthesis that a point mutation?
A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.
"Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
Here is an example of one sentence with words of only three letters: The big red pig ate the red rag. Each word will make one amino acid and the words make a sentence that makes sense.
Mutations that replaces one base for another will result in this: The beg red peg ate the red rag. This mutation can be read OK.
But another type might make the sentence totally readable: The big res dpi gat eth ere dra.
What else can I help you with?
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.
Can a frameshift mutation be a silnt mutation?
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
What is the er usually attached to?
The endoplasmic reticulum (ER) is usually attached to the nuclear envelope in eukaryotic cells. It forms a continuous membrane system that extends throughout the cytoplasm, facilitating the synthesis of proteins and lipids. The rough ER, which has ribosomes on its surface, is specifically involved in protein synthesis and processing, while the smooth ER is associated with lipid synthesis and detoxification processes.
What is the name of the process of building up large proteins in a cell?
Protein synthesis requires two steps: transcription and translationMessenger RNA (mRNA) a copy of a portion of the DNA. It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein. Proteins are created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (Posttranslational modification) to give the mature protein.
What will happen if there was a change in the base pair sequence?
Changing a base pair on a human chromosome (or any organism's chromosome) can range from no effect to catastrophic. The changing of a base pair -- a mutation -- can either result in a nonsense mutation, a missense mutation, or a silent mutation.A nonsense mutation changes a codon upstream of the normal stop codon into a stop codon, resulting in a truncated protein. Such proteins are non-functional and usually result in a non-viable offspring although some can survive (with serious genetic disorders).A missense mutation is just like a nonsense mutation, except the codon isn't changed into a stop codon and the protein does not terminate early. The only difference between the normal protein and the affected protein is that the affected protein will have one amino acid along the polypeptide chain that is different. The affects of such a change can change the shape of the protein entirely, seen with sickle-cell anemia.A silent mutation has no effect on the protein produced. There are only 20 amino acids, but 43 variations of four bases arranged three at a time (in other words, there are 64 different codons possible). Accordingly, more than one codon can code for the same amino acid. For example, both UAU and UAC code for the amino acid tyrosine. Imagine a point mutation replaced the U in UAU with a C making it UAC. Either way, the amino acid that will be used will be tyrosine, in no way changing the structure of the protein. For that reason, these mutations are "silent" or having no effect.
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.
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.
Why does an insertion mutation usually cause more defects in 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.
Why does an insert mutation usually cause more defects during protein synthesis than a point mutation?

How does a mutation that alters a codon for a specific amino acid to a different codon for the same amino acid affect protein synthesis?
When a mutation changes a codon for a specific amino acid to a different codon for the same amino acid, it usually does not affect protein synthesis. This is because multiple codons can code for the same amino acid, so the change may not alter the final protein product.
If one of the nitrogen bases were replaced by a different base what effect might that have on protein synthesis?
It depends. Because many amino acids have more than one codon, it may not affect the protein at all. However, if it does change the amino acid sequence, it could cause a change in the three-dimensional structure of the protein, resulting in a mutation.
What amino acid is usually the first one inserted into a protein during protein synthesis?
A protein is a topic that is vital, and that requires professional tending to regarding
Why does a deletion mutation usually cause more defects during protein synthesis than point mutation?
A point mutation will change only one particular base of the codon, so it will only cause a change in one of the amino acids that will make up the protein. A deletion mutation will completely remove a base- causing a change in every amino acid that follows the deletion. Here is an example with a sentence, using three letter words (since amino acids are determined from 3 letter codons). THE FAT CAT ATE ONE RAT. A point mutation would change only one letter (like changing the C to a B). The new sentence is only slightly changed: THE FAT BAT ATE ONE RAT. A deletion mutation would remove a letter (like deleting the C). The new sentence will now be completely changed from the deletion on. THE FAT ATA TEO NER AT. See the difference??? Point mutations usually take place during DNA replication. A single point mutation can change the whole DNA sequence.
