What else can I help you with?
If an enzyme is absent during polypeptide production a mutation can occur?
Yes, if an enzyme necessary for polypeptide production is absent, the process may be disrupted. This could potentially lead to errors in translation, such as misincorporation of incorrect amino acids, which can result in a mutation in the polypeptide sequence.
What could account for low endonuclease activity?
Low endonuclease activity could be due to improper folding or denaturation of the enzyme, suboptimal pH or temperature conditions for activity, or lack of cofactors required for enzymatic function. Additionally, mutations in the gene encoding the endonuclease enzyme could also lead to reduced activity.
Changing one amino acid with a protein could change what about the protein?
It will depend on how different the amino acid is to the one it replaced. If the structure and/or charge is quite different, a change of one amino acid can change the entire 3D structure of the protein. This will affect the proteins function.
What are three possible outcomes of a mutation?
There are three categories of point mutations:Nonsense - the mutated codon is now a stop codon, severely truncating the polypeptide. The protein will no longer function.Missense - the mutated codon now codes for a different amino acid, which alters the structure of the polypeptide. If the protein is still functional, it may be inhibited by its different structure, seen in sickle cell anemia. The changed polypeptide may also benefit the organism with a positive phenotype, which fuels evolution.Silent - because different arrangements of bases can code for the same amino acid, a mutated codon could code for the same amino acid as before. Effectively, the mutation did not change anything about the polypeptide ― hence, it is "silent."
How many polypeptide chains are in a protein?
There is one polypeptide chain in a single protein chain. Polypeptides refer to short protein chains - for example insulin is a 53 amino acid protein and is considered a large polypeptide. Complex multi-component [strand] protein coalescences exist - each uniquely identified component protein strand is called - of course - a subunit: two subunits is called a dimer, three subunits is called a trimer, four is a tetramer etc. A Protein is a string of Pearls {Amino Acids} of which [out of the quadrillion possible] there are ONLY Twenty Biologically Active Types ( with two, sometimes three, more reserved for special occasions ). A common example of a biological multi-strand protein grouping is: 4 strands will combine thusly - 2 strands of one type and 2 strands of another type.
How could the climate change affect the ecosystem of the island nation of Samoa?
increased cyclone activity could damage land plants and coral reefs
What errors could affect a science activity?
to affect a science activity you can drop it and it would lower the mass
How can censorship negatively affect economic activity?
Censorship could negatively affect economic activity by not allowing people to know about or have access to products. This could drive up prices or cause financial hardship to companies.
Could the number of sunspots affect the amount of volcanic activity on earth?
Highly unlikely.
How might amino acid change affect the enzyme?
The pKA of enzyme affects its ionization which could alter enzyme activity. For pH < pKa, the value of vmax is constant and that for pH > pKa, vmax decreases; ie. enzyme activity starts to decline.
How could an earthquake affect the behavior of geyser activity in yellow stone?
An earthquake could affect geyser activity in Yellowstone by potentially altering the underground hydrothermal system that feeds the geysers. It could disrupt the flow of water and change the pressure within the system, impacting the timing and intensity of geyser eruptions. Additionally, an earthquake could trigger new geysers to form or cause existing ones to become dormant.
The backbone of a polypeptide could be represented by?
The backbone of a polypeptide could be represented by a chain of nitrogen and hydrogen atoms. The polypeptide backbone is the key contributor to protein secondary structure, which involves backbone-to-backbone hydrogen bonding.
What could affect an ecosystem?
the factor that affect and change the ecosystem is how the people living
How does voting affect England?
The government could change on the outcome of an election.
What could happen to earths surface if there was a change in the water cycle?
There could be change in the content of water. It will affect the level of water in the water bodies.
When is the polypeptide (protein) released from the ribosome?
Polypeptides are proteins, just they are short. For example, Insulin is a protein of just 56 amino-acids; it could be considered to be a very large polypeptide.
Could tornadoes cause global warming?
No. While global warming might affect tornado activity, tornadoes themselves are an end product of weather and climatic activity, not a cause.
