A mutation MAOA gene is associated with a predisposition to different sets of behavioral disorders which can be triggered by environmental factors. This is due to variation in the a)promoter b)in the middle of the gene c)near the end of the gene d)deletion of the gene
Homework Answers
MAOA gene encodes an enzyme called as Monoamine oxidase A in human. This gene mutation is associated with a predisposition to different sets of behavioral disorders which can be triggered by environmental factors. This variation is due to deletion of gene. Hence, correct option is d.

Due to a recessive mutation in gene A, amino acid ‘Glu’ in position 25 of polypeptide A (the wild polypeptide) is replaced by ‘Ala’. Individuals who are homozygous for the mutant allele (aa) don’t have any phenotypic alterations. Based on this observation, which of the following IS TRUE? A. The mutation has occurred in the promoter. B. The mutation has occurred in one of the introns of the encoding gene. C. The mutation was a base substitution in one of...

A cell that is heterozygous for a nonsense mutation in a tumor suppressor gene would most likely: A) Group of answer choices B) grow but not divide C) have a normal cell cycle D) arrest and induce apoptosis E) have a slightly increased cell cycle and increased cell growth F) grow and divide uncontrollably Which of the following correctly describes an event that occurs during transcription: Group of answer choices A) A DNA molecule is chemically modified to become a...

Which of the following mutations would be most likely to have a harmful effect on an organism? (A) a deletion of three nucleotides near the middle of a gene (B) a single nucleotide deletion in the middle of an intron (C) a single nucleotide deletion near the end of the coding sequence (D) a single nucleotide insertion downstream of, and close to, the start of the coding sequence In this problem, why (c) cannot be the answer?? Single nucleotide deletion...

1) Is the mutation in the SFSU fly in the SAME or DIFFERENT gene as the mutation in the Stanford fly? To determine this, which cross should we perform? A. Cross the SFSU fly in a testcross B. Cross the Stanford fly in a testcross C. Cross the SFSU fly with a wild type fly D. Cross the Stanford fly with a wild type fly E. Cross the SFSU fly with the Stanford fly

A number of mutants were isolated in yeast that are auxotrophic for leucine. Different crosses were performed between the different Leu- strains. In which of the following crosses would a geneticist expect the resulting diploid to grow on medium lacking leucine? A. A diploid containing two mutant alleles of the same gene that have the same nucleotide sequence. B. A diploid containing two mutant alleles of the same gene that have different nucleotide sequences. C. A diploid with a point...

One allele of the APOE gene is associated with early Alzheimer’s disease, while another allele appears to help prevent Alzheimer’s. In a brain cell of an individual with the first type of allele, we find high levels of the protein. In the brain cell of an individual with the second allele, we find no protein. This indicates the mutation may be found in: A. an intron in the gene B. the stop codon C. the 3' UTR D. the promoter...

If there is a mutation in the gene for collagen, such as the one involved in Ehlers-Danlos syndrome, and the individual produces defective collagen, how would it affect coagulation? a. The syndrome affects the clotting factors and platelet aggregation. b. The syndrome leads to hyper-coagulation of blood. c. Coagulation is not affected because collagen is not required for coagulation. d. The syndrome occurs due to the breakdown of platelets.

1) Suppose that gene A 3,000 bp. Suppose that g contained within intron 1 opposite directions for the two genes. covers 10,000 base pairs (bp) and has 2 exons; the intron in gene A is ene B covers 1,500 bp and has two exons. Gene B is completely of gene A. The direction of the transcriptional bubble moves in A. Draw the genomic organization (i.e., exons and introns) of gene A AND gene B. Label the polarity of the DNA...
