13. Which of the Following Is Not True About Mutations

- In-frame mutations that add or remove only one amino acid may still affect the phenotype. A single-base insertion is usually more harmful than a single-base point mutation.

A Mutation refers to both change in the genetic material and the process by which the change occurs b Point mutations involve changes at specific sites in a gene c If a mutation occurs in a somatic cell the mutant phenotype will be passed on to the offspring of that organism.

. Mutations cant result in a change in appearance. A mutation is permanent. Somatic mutations are passed to offspring.

Which of the following about mutation is TRUE. - In-frame mutations occur when insertions and deletions involve any multiple of three nucleotides. 6 Which of the following statements is not true about mutation.

Mutations and Genetic Testing. Mutations can be passed from parent to child. Which of the following is not true about mutations.

- DNA deletion andor insertion can cause frameshift mutations or in-frame mutations. Mutagens and meiosis are two sources of mutation. Mutations can be passed from parent to child.

Mutations can be useful to the organism. Williams syndrome is caused by the loss of an end of chromosome number 7. All mutations are harmful to the organisms genome.

Without knowing the animal it would be hard to tell whether or not the mutation would be passed on. Which of the following is NOT a syndrome resulting from a variation in chromosome number. Mutations cant result in a change in appearance.

Mutations cant result in a change in appearance. Mutations are not random b. All of the above.

Mutations in body cells affect only the individual and are not passed on to the offspring. A They involve the replacement of a purine by a purine b A mutation in the first position of a codon usually results in a missense mutation c They involve the substitution of a single nucleotide d A mutation in the third position of a codon usually results in a missense mutation e They can. Which of the following is not true of mutations.

Which of the following statements about mutation is TRUE. A mutation can result in a change of function. A mutations are chance changes in the DNA sequence of bases and may code for a different amino acid B mutations may cause variations that are adaptations C radiation and X-rays may cause mutations D mutations are always harmful.

A Silent mutations are changes in DNA sequence that alter the amino acid and they do not change the biological function of the altered sequence. Sex cells only use half of the bodys genetic code. This is NOT true of Mutations.

Mutations in eggs or sperm affect future generations by transmitting these changes to their offsprings. Mutations may affect only one gene or they may affect whole chromosomes. Learn vocabulary terms and more with flashcards games and other study tools.

Mutations cant result in a change in appearance. The correct option is D Mutations inhibit production of telomerase Cancer is a disease which causes abnormal cell growth with the potential to invade or spread to other parts of the body. Only mutations that occur in the sex cells that are passed on to the offspring.

Cancer is caused by increased telomerase activity making the cancerous cells immortal and not by inhibition of telomerase production. Mutations cant result in a change in appearance. Yes because any change to the DNA is passed on to the offspring.

A mutation is permanent. Mutations give rise to new alleles that may be harmful or beneficial c. E - None all of the above statements are true.

Insertions but not deletions can change the codon reading frame. Mutations respond to selective pressures by producing new forms of genes that are needed at the moment. Which of the following is NOT true of transition mutations.

A mutation can result in a change of function. B Neutral mutations are changes in DNA sequence that are reversed by a second mutation resulting in the same amino acid as the original unmutated amino acid. A mutation is permanent.

Mutations can be passed from parent to child. Start studying Chapter 13. It might get the copy of a gene that wasnt mutated.

This is NOT true of Mutations. A mutation can result in a change of function.
