Homework Answers
Answer 20: Two linked genes that are close together usually have a lower recombination frequency than two linked genes that are further apart. Because there is smaller chance that they will separated.
Answer 21: DNA polymerase III requires RNA primer to build something before it can begin replication. because the DNA polymerases, can only attach new DNA nucleotides to an existing strand of nucleotides.
Answer 22: Non sense mutations in a gene always results in a new stop codon in the transcribed mRNA.When this mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal.

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...

Question 23 3 pts A plant that is homozygous recessive for mangled leaf and prickly fruit (mmpp) is crossed with the double heterozygote (MmPp), resulting in 1047 offspring: 472 with mangled leaves (mP), 453 with prickly fruit (Mp), 63 wild type (MP), and 59 with mangled leaves and prickly fruit (mp). From these data, you can conclude that o The M and P genes are located 11.7 CM apart o The M and P genes...

Question 2 Genes a and b are linked, with 20% recombination frequency. Two pure breeding strains (the parental cross) were crossed. The F1 was then testcrossed. a+b-/a-b+ x a-b-/a-b- What were the parental strains genotypes? b. What would be the genotypes and the probability of each, among progeny of the testcross? Example: a+b+/a-b- 45% c. Is this an example of cis- or trans-linkage?

QUESTION 1 George Beadle and Edward Tatum performed an experiment in which they made single-gene mutations in the bread mold Neurospora crassa. These mutations resulted in several Neurospora auxotrophs. Further analysis revealed specifically how the mutations affected synthesis of the amino acid in question. What was the significance of these results? A single gene encodes a single protein, in the case of this experiment, an enzyme. Enzymes are needed to synthesize amino acids. They showed that mutations are heritable. They...

Question 9 3 pts Although the MHC locus tends to be inherited as a unit called a haplotype, in some cases a child receives a combination of two haplotypes from one of their parents. Which of the following is likely responsible for this? Crossing over outside of the MHC locus during meiosis Recombination during DNA damage repair within the MHC locus in the parent's somatic cells Inheritance of different haplotypes from each parent Crossing over within the MHC locus during...

Why would changes in the genes for transcription factors be expected to generate major phenotypic differences?...
Why would changes in the genes for transcription factors be expected to generate major phenotypic differences? They are extremely powerful genes. They can affect the expression of small numbers of other genes. Their gene products are remarkably stable. Their gene products normally denature more rapidly than other gene products. They can affect the expression of large numbers of other genes. Which enzyme, also responsible for siRNA formation, carves miRNAs from their double-stranded, fold- back RNA precursor (pre-miRNA)? Dicer ribonuclease RNA...
