Which types of mutations cause (1 word)  a. Increase amount of genetic material in particular chromosome  b increase amount of genetic material in all chromosomes  c decreased amount of generic material in particular chromsomes  d change to position of dna sequence in singular chromosome without changing the amount of genetic material  e move dna from one chromosome to non homologous chromosome

A chromosome initially has the following segments:A B • C D E F G Draw the chromosome, identifying its segments, that would result from the following mutations. Q.Deletion of FG

We are not single celled organisms and multiple cell divisions occur between fertilization and production of gametes. In males there are an estimated 400 divisions before production of gametes and in females about 30 divisions. Can you think of why this is? Is a new mutation arising from DNA replication more likely to occur because of errors in the male or the female germline?

Chromosome initiated has following sequence    ab*cdefg *= centromere  draw the chromosome that would result from the following mutations    a paracentric inversion that includes defg  b peri centric inversion of bcde

Your friend sends you two cancerous cell lines to examine and determine possible mutations. The results are shown below: Cell Line Mutation WT none (wild type DNA) 1 a deletion at the same region on both copies of chromosome 4 a point mutation in a gene on only one copy of chromosome 7 Based on this data, what type of geńe is mutated in each of the cell lines? Select all that apply O Cell line 2 has a mutation in an oncogene Cell line 1 has a mutation in a tumor suppressor gene Cell line 1 has a mutation in an proto-oncogene Cell line 2 has a mutation in a tumor suppressor gene
