Explain how a base analog can cause a mutation, including how the base analog gets incorporated...
2. A substitution mutation is one in which one nucleotide base is changed to another Suggest ONE substitution A G mutation in the DNA that would cause the first amino acid in the "# of Eyes" gene to change from alanine (Ala) to valine (Val). In the table below, write the original.3. There is a substitution mutation in the gene for Fangs in which the first DNA base changes from guanine to thymine. The mutation results in a genetic disorder...
1. Factors that contribute to the mutation rate of any gene include: Choose all correct. A. The size of the gene B.The protein the gene will give rise to after translation C.The nucleotide sequence (DNA or mRNA) D.Spontaneous chemical changes E. The location of the gene on the chromosome (What is the correct answer) 2.Trinucleotides are really just: A. A codon that will be read and converted into a single amino acid in a protein sequence B.A piece of DNA...
DNA: Base pairing < 1 of 15 > The structure below is an unnatural analog of adenosine. If it were synthetically incorporated into a DNA strand in place of dA, what is the maximum number of hydrogen bonds it could make with dT in the complementary strand? NH -NH₂ HO H ΠΗ ОН Н V AX&D + 0 2 ?
Short Explain and tyoe please explain how a single base mutation can have a huge affect on the expression of a gene. Why are most of these mutations devastating for gene expressions? How can they sometimes be beneficial? Use sickle-cell anemia as a case study for answering this question.
1) When a mutation occurs by elimination of one base in a DNA sequence, this mutation is called a Explain. a) deletion mutation b) substitution (point) mutation c) translocation mutation d) viral mutation 2) Acids and bases denature a protein by disrupting peptide bonds and salt bridges amide bonds and alkene bonds hydrophobic interactions and peptide bonds Aluminum reacts with sulfuric acid. It produces a gas, and an aqueous solution. What mass (in g) of aluminum would completely react with...
Explain how the mutation would cause the clinical manifestations of sickle cell anemia?
Type of Mutation Change and what base(s) it might effect Spontaneous or induced? Cause (if known) How mutation impacts dsDNA Write dsDNA showing the mutation Depurination Oxidative reactions Strand slippage Unequal crossing over
please help 6. How can a missense mutation-such as in sickle cell disease-result in a protein that has an abnormal structure? Some of these mutations are lethal or cause serious disease, such as cystic fibrosis and sickle cell disease. Many of these point mutations that cause genetic disorders occur as a result of errors in DNA replication or crossing over. 7. What will be the consequence if a single base is deleted from the coding region of a gene?
This question is about DNA damage, repair and mutation. a) State a type of mutagen that could produce a single base pair substitution mutation. Briefly describe how this mutagen can produce single base pair substitution mutations. [4 marks] b) For your mutagen from (a), briefly describe the repair process that could repair the DNA damage. [4 marks] c) Propose how a single base pair substitution can be a hypomorphic allele. Explain how your mutation fits the definition of a hypomorphic...
