Question

1.) Which of the following is false?

a.) The high degree of identical sequences between two people make finding DNA differences very difficult

b.) The high amount of repeated regions in the human genome make it difficult to sequence and assemble

c.) SNP comparisons require a reference where polymorphism sites are established within a population

d.) Copy number variation can be identified by restriction enzymes in DNA fingerprinting assays

e.) All of these statements are true.

-   

2.) What type of sequence can be used to find and annotate protein coding genes?

a.) Open reading frames

b.) Start codons

c.) All methionine codons

d.) Sequences only in reading frame 1

e.) None of these answers are correct

-

3.) What is the difference between the L1 elements and the Alu elements?

a.) All of these answers are correct

b.) L1s are LINEs and Alus are SINEs

c.) Alu does not encode its own enzymes to allow it to move

d.) L1s are more prevalent in the human genome

e.) Alu insertions have been linked to inherited diseases and cancers.

Answer 1

1) The correct answer is "a.) The high degree of identical sequences between two people make finding DNA differences very difficult". The given statement is false because differences can be determined using restriction digestion patterns by DNA fingerprinting irrespective of sequence similarities.

2) The correct answer is "a.) Open reading frames". Open reading frames (ORFs) include both start and stop codons enabling the identification of coding genes.

3) The correct answer is "a.) All of these answers are correct".
