What is a point mutuation?
A point mutation is a type of genetic mutation that involves a change in a single nucleotide base pair in DNA. This can result in the substitution of one nucleotide for another, the insertion of an extra nucleotide, or the deletion of a nucleotide. Point mutations can lead to changes in the amino acid sequence of a protein, which can affect its structure and function.
How do mutations affect proteins?
. by changing the number of mRNA bases that make up the codons 2. by preventing the ribosome from binding to the mRNA 3. by changing the sequence in amino acids brought to the ribosome 4. by creating codons with no complimentary anti-codons
What are the impact of mutations and how mutations can have no impact?
Mutations are usually anomalies in the sequence of a particular strand of DNA. The change is the sequence can be of various kinds and their individual effects vary. Sometimes mutations occur but they are never expressed. In such cases, on the whole, the mutation has had no impact. Changes in a single nucleotide can change the reading frame for protein coding regions and can cause misreading of the genetic code. For example, nonsense mutations caused by the exchange of a nucleotide leading to a stop codon can cause truncation of a protein. On the other hand, we can have silent mutations which show no effect because the nucleotide that has been exchanged does not cause change in amino acid sequence. So this would be an example of a mutation which shows no effect.
What does the tertiary structure of a protein tell you about the protein?
It tells us about the three dimensional structure of the protein in its folded configuration.
How can mutation affect protein synthesis in cell?
Mutations can make the protein synthesise incorrectly making diseases or weak parts in your body. Mutations can affect protein synthesis in cells by affecting the protein, messing up the whole DNA sequence and making the organism different from other average organisms.
What is the definition of chromosome mutation?
A chromosome is an organized structure of DNA and protein that is found in cells.In biology, mutations are changes to the nucleotide sequence of the genetic material of an organism.

Why can some gene mutatuions be harmful while others have no effect?
Let's consider a simple example: protein-coding genes. Mutations, or changes in the DNA sequence of the gene, can alter the amino acid sequence of the protein it codes for, if the new sequence translates into different amino acids. Because the genetic code is degenerate, some amino acids are specified by multiple codons, so some mutations may not alter the amino acid sequence at all. Such mutations, called synonymousmutations, have no affect on the protein. Mutations that alter the amino-acid sequence of the protein, called non-synonymousmutations, may or may not have an affect. Most proteins can tolerate some changes to that sequence and not be significantly affected, but if the sequence change is large enough, or occurs at a critical point so that the structure of the protein is significantly altered, then the protein may become non-functional. If that protein is essential to an organism, such a mutation may be lethal.
How is tertiary protein structure dependent on primary protein structure?
The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain.orThe sequence of amino acids in a primary structure determines its three-dimensional shape ( secondary and tertiary structure)
Do all mutations affect the protein results?
No. Point mutations may have no effect on the protein, however, they can also be very harmful.
How is the biochemical evidence of protein comparisons used in determining evolotionary history?
When the protein structure changes there has been evolution in the organism
How can mutations affect protein synthesis in cells What is the result?
Mutations can be a source of genetic
What is a change in the structure of a protein due to changes in the environment like temperature or pH.?
denature
What effect does insertion have on the protein produced?
A BIG effect! An insertion changes the reading frame and can result in a completely different protein being formed which will probably be non-functional. These mutations are very detrimental.
Why do kinds of point mutations cause greater changes in proteins than othere?
Because not every point mutation changes the protein. If it doesn't change, we call it a silent mutation or when one letter is deleted at the beginning, than the whole chain changes, but if it's at the end only the and changes so it's a bigger effect on the protein :p
