Anyone good at Genetic Mutation?

Anyone good at Genetic Mutation? Topic: Examples of writing letters
July 19, 2019 / By Niven
Question: Please help. 1. A geneticist found that a particular mutation had no effect on the protein coded by a gene. what do you think is the most likely type of mutation in this gene? why? 2. Look at the following sequence: THE FAT CAT ATE THE RAT. Delete the first H and regroup the letters in groups of three- write out the new groups of three does the sentence still make sense? What type of mutation is this an example of? 3. Below is the base sequence for the normal protein hemoglobin and the base sequence for the sickle cell hemoglobin. Normal GGG CTT CTT TTT Sickle GGG CAT CTT TTT a. Transcribed and translate the normal sickle cell DNA. b. Identify this as a point or frameshift mutation. explain. c. If the base sequence read GGG CTT CTT AAA instead, would this result in sickle cell hemoglobin? Explain.

1. A geneticist found that a particular mutation had no effect on the protein coded by a gene. what do you think is the most likely type of mutation in this gene? why? Ans. This is an example of silent mutation. In silent mutation there is change in codon but there is no change in amino acid because an amino acid can have more than one codons (Degeneracy of Genetic Code).Therefore, there would be no change in the protein 2. Look at the following sequence: THE FAT CAT ATE THE RAT. Delete the first H and regroup the letters in groups of three- write out the new groups of three does the sentence still make sense? What type of mutation is this an example of? Ans.Addition or deletion of bases changes the reading frame & results in Frame Shift Mutations. 3.Sickle cell anaemia is an example of Point Mutation.It is due to single gene defect.There is change in codon from GAG to GUG in the Beta chain of haemoglobin.Due to change in codon glutamic acid is replaced by valine aminoacid

Kori Originally Answered: How do natural selection, gene flow, genetic drift, and mutation apply to evolution of genus homo?
Like a Velcro tennis ball falling down a hill. Each thing encountered affects the end result. Those things that stick have lasting affects upon future attachments. Those things that impact and dislodge can return the ball to a previous state or cause random reactions/changes.

1.I think it would have to be a point mutation because a frame shift mutation would change the set of amino acids coded for whereas the point mutation would maintain the same frames to read the codons so that only one amino acid would be affected by the change. It sounds like the mutation resulted in a codon that happened to code for the same amino acid as the original codon. 2. TEF ATC ATA TET HER AT Frameshift mutation (illustration) This type of mutation occurs when the addition or loss of DNA bases changes a gene’s reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid. A frameshift mutation shifts the grouping of these bases and changes the code for amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift mutations. 3. A. gly, leu, leu, phe B. POINT --the change only affects a single amino acid and does not change the codon spacing because it is not an insertion, deletion or duplication C. it would result in a change in the protein because lys would replace phe Lys has a positively charged side chain whereas phe has a hydrophobic side chain. This would mean that the protein folding would be affected. Clinically important missense mutations generally change the properties of the coded amino acid residue between being basic, acidic polar or non-polar, whereas nonsense mutations result in a stop codon. Since the replaced amino acid change is in a different location and the original sickle cell mistake replaced the nonpolar leu with the basic his I doubt that replacing phe with lys would result in sickle cell disease although it would result in some disease because the protein folding would be affected.

We did not find any results for 'you have DNA sequence that codes for a protein is 105 nucleotide long. A frameshift mutation occurs at the 85th base- how many amino acide will be correct in this protein?'

of course that is using a genetic mutation. maximum human evolution is via genetic mutations -- no longer something specific approximately it. And confident, it explains why Asian ethnic communities have not got blond hair and blue eyes -- Their DNA would not have the mutation. yet what precisely are you getting at right here? that is only logical that diverse eye hues, pores and skin hues, etc arose from genetic mutation. And what do you recommend via familiar? there's a extensive inhabitants with easy eyes and hair, that is not clever to call it odd. effective, there may be extra those with darkish pores and skin and brown eyes, yet this is rather no grounds to call one team extra familiar than the different.

Cory Originally Answered: Is gender dysphoria genetic? Is dysphoria genetic in every case?
"Is gender dysphoria genetic? Is dysphoria genetic in every case?" No. It is a developmental variant. Most people are born with a gender identity in their brain that matches the sex of their body, transsexual people are not. That's what transsexualism is, a birth condition. This leads to a life of pain and misery as their body feels profoundly wrong and nobody ever sees them as the person they truly are. Transsexual people transition (aka "sex change") to affirm their inborn gender identity by changing their body to match and assuming a gender appropriate role in society. Transsexualism is a scientifically proven birth condition. "Usually identical twins have the same DNA that makes them identical" Not so fast. Even "identical" twins aren't really identical. For example, their fingerprints. From conception the environment in which an individual grows and develops is unique. This is why identical twins aren't really aren't identical and why such twins can have different sexual orientations and gender identities. EDIT: "Please explain to me the difference between transgender and transsexualism?" It's complicated. “Transgender” is an umbrella term that covers many diverse groups that have little or nothing to do with each other. Many people assume it refers just to transsexual people, but they are wrong. Transsexual people only represent a small fraction of those who are considered “transgender”. And for the record a transsexual person is someone who was born with a brain-body mismatch, literally a female brain in a male body or vice-versa. It is a naturally occurring birth condition. Through the process of TRANSITION transsexual people change their bodies to match the true inner gender and assume a gender appropriate role in society. Also one does not “become” transsexual; as I said we are BORN that way. “Transgender” refers to anyone who varies from the societal norms for their gender as assigned at birth. Other than transsexual people other groups under the transgender umbrella include: Cross-dressers (obsolete term was “transvestite”) Androgynes Gender fluid Genderqueer Genderf*ck A-gender Bi-gender Two-spirit Neutrois And more. You can read more about gender identity and transsexualism here: http://forum.beginninglifeforums.com/index.php/t/15139/e006e3edb4dda238f417a04f0457008c/ http://ai.eecs.umich.edu/people/conway/TS/TS.html#anchor107763 To further complicate things: Many transsexual people don't like to use the term "transsexual" because of the stigma attached to the word, so many think it's about sex, not gender. Anywho, as a result many transsexual people today use the umbrella term "transgender" instead. You really have to ask the person involved which they prefer. Personally I don't use either term except when I'm online. Off-line I'm just plain female. .
