Question 4

The phenomenon referred to as RNA interference refers to __________.

A) the ability of short snippets of RNA to silence the expression of targeted genes
B) repetitive sequences that do not code for proteins ("junk DNA")
C) the correlation of single-base DNA variations (SNPs) among individuals with disease
D) the differences between species depending upon the numbers of genes in DNA

Question 5

Which of the following was NOT a goal of the Human Genome Project (HGP)?

A) Identify all of the genes in human DNA
B) Determine the sequences of the 3 billion chemical base pairs (A, T, C, G) that make up human DNA
C) Store this information in databases
D) Find cures for specific diseases

Question 6

The order of almost all (99.9%) __________ is exactly the same in all humans.

A) human protein coding genes
B) nucleotides
C) DNA sequences
D) nematodes

Question 7

Which of the following was learned from the Human Genome Project (HGP)?

A) How genes are regulated
B) The organization of DNA sequences
C) The average gene consists of 3000 bases, but sizes vary greatly
D) The structure and organization of chromosomes

Question 8

According to the findings of the Human Genome Project, more than 2% of the genome encodes for the production of proteins.

Question 9

Repetitive sequences that do not code for proteins ("junk DNA") make up at least 50% of the human genome.

Question 10

Scientists were shocked to discover through the Human Genome Project that humans have a surprisingly low number of genes-about the same as the simple roundworm.

Question 11

The functions of the vast majority of discovered genes are well understood.
