Question 21 of 40 2.5/ 2.5 Points What is the difference between a karyotype and a karyogram?
Feedback:Learning Objective: Describe how a karyogram is created Question 22 of 40 2.5/ 2.5 Points A karyogram that contains 23 pairs of chromosomes with a different pair for the 23rd pair would describe a(n)
B. male C. female D. disorder Feedback:Correct Question 23 of 40 2.5/ 2.5 Points What causes RNA polymerase to stall so that the rho protein bumps into it and knocks it off the DNA?
Feedback:Learning Objective: Describe how and when transcription is terminated Question 24 of 40 2.5/ 2.5 Points Which is likely to disrupt the function of the most genes: a 500kb deletion, a 500kb inversion, or a 500kb translocation? A. Deletion B. Inversion C. Translocation Feedback:The deletion will disrupt all the genes contained within it, but the inversion and translocation will likely only affect the genes on the ends. Question 25 of 40
2.5/ 2.5 Points If a family has a child with Down syndrome (trisomy-21), then one of the siblings must be monosomic for chromosome 21. Question 26 of 40
2.5/ 2.5 Points The allele for widows peak (H) is dominant for the allele for no widows peak (h). At a different gene locus, the allele for hitchhikers thumb (D) is dominant to the allele for non-hitchhikers thumb (d). A man is heterozygote for the traits and marries a woman who has no widows peak and is heterozygote for hitchhikers thumb. What is the man’s genotype?
Feedback:Learning Objective: Use the forked-line method and the probability rules to calculate the probability of genotypes and phenotypes from multiple gene crosses
