What else can I help you with?
What amino acid is technically not an amino acid?
proline is not an amino acid it is an imino acid
Suppose part of an amino acid sequence of a protein changed from tyrosine proline glycine alanine to tyrosine histidine glycine alanine this change was most likely caused by a point mutation called?
This change was most likely caused by a point mutation called a missense mutation. Missense mutations involve the substitution of a single nucleotide in the DNA sequence, leading to a change in one amino acid in the protein sequence. In this case, the substitution of a single nucleotide led to the change from tyrosine to histidine in the protein sequence.
How do you go from a chloride to nh2 group?
To convert a chloride to an amino group (NH2), you can perform a nucleophilic substitution reaction. One common method is to react the chloride with ammonia or an amine in the presence of a base. This substitution reaction replaces the chloride with the amino group, resulting in the desired product.
Why lysine and threonin do not undergo transamination?
L-lysine does not participate in transamination. It is the exception to the general rule that the first step in catabolism of an amino acid is the removal of its alpha- amino group by transamination to form the respective alpha-keto acid
What is a dispensable amino acid?
A dispensable amino acid, also known as a nonessential amino acid, is an amino acid that the body can synthesize on its own and does not need to be obtained from the diet. There are 11 dispensable amino acids in humans.
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
In terms of producing a changed protein which causes a more drastic change- base substitution or additiondeletion?
Base substitution, due to the way the RNA translates into amino acids for the proteins, simply causes one amino acid to be different. Addition or deletion, however, cause the entire chain to shift, meaning each amino acid from that point in the chain on will be changed, creating an entirely different protein.
What type of mutation causes sickle cell anemia substitution deletion insertion mutagen?
The type of mutation that causes a defect in the gene (causing sickle cell anaemia) is a substitution mutation.A single nucleotide substitution (A to T) in the β-globin gene causes the amino acid valine to replace glutamic acid. This changes the resulting protein, causing a haemoglobin with an abnormal shape to be created.
What type of mutation causes protein to be synthesized with one incorrect amino acid?
Missense
Sickle cell is caused by an amino acid substitution of valine for?
yes
Which type of mutation does not change the amino produced?
Well consider the substitution of one hydrophillic amino acid for another hydrophillic amino acid. This type of mutation changes nothing but a molecular marker. or Silent
What happens during a substitution mutation and how does it impact the genetic code?
During a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can lead to a change in the amino acid that is coded for, potentially altering the protein that is produced. The impact on the genetic code depends on whether the substitution results in a silent mutation (no change in the amino acid) or a missense mutation (change in the amino acid), which can affect the function of the protein.
Changes in a DNA sequence caused by substitution of one nucleotide for another?
A substitution mutation occurs when one nucleotide in a DNA sequence is replaced with a different nucleotide. This can lead to a change in the corresponding amino acid in the protein produced from that gene, potentially altering the protein's structure and function. Substitution mutations can be silent (no change in the amino acid), missense (change in one amino acid), or nonsense (premature stop codon).
An example of mutation?
The substitution of one triplet code in the DNA that codes for an mRNA that codes for an amino acid that makes up a protein. Sickle cell trait is an example of this. One amino acid substitution in a B chain of hemoglobin and you have an allele that will code for sickle cell trait.
Which type of mutation does not change the amino acids produced?
Well consider the substitution of one hydrophillic amino acid for another hydrophillic amino acid. This type of mutation changes nothing but a molecular marker. or Silent
Where does amino acid synthesis occur in the body?
Amino acid synthesis occurs in the body primarily in the liver and to a lesser extent in the kidneys.
How does a single amino acid substitution cause hemoglobin molecules to stick together?
A single amino acid substitution, such as the one in sickle cell anemia where glutamic acid is replaced by valine, can cause hemoglobin molecules to stick together due to a change in the structure of the protein. This structural change leads to the formation of abnormal hemoglobin polymers that can distort the shape of red blood cells, leading to their sickling and contributing to various complications.
