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.
What term is defined as any change in the genetic code on DNA and usually occurs during replication.?
it is known as mutation
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.

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
What are inducible and non inducible enzymes?
Inducible: usually off for protein synthesis but can be turned on Non inducible, or REPRESSIBLE : usually on for protein synthesis but can be turned off Inducible: usually off for protein synthesis but can be turned on Non inducible, or REPRESSIBLE : usually on for protein synthesis but can be turned off
What is the significance of the mRNA start codon in initiating protein synthesis?
The mRNA start codon, usually AUG, plays a crucial role in initiating protein synthesis. It signals the ribosome to start translating the mRNA sequence into a protein. This codon marks the beginning of the protein coding sequence and helps establish the correct reading frame for translation.
Why is a silent mutation called silent?
a mutation that does not affect protein production.
What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.
Synthesis of a protein stops when?
Synthesis of a protein stops when a stop codon is reached on the mRNA during translation. This signals the ribosome to release the newly synthesized protein so it can fold into its functional structure.
Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Deletion mutations can affect the entire base sequence.
