DNA carries the cell’s genetic information; however, it cannot leave the .
Because of this, it copies part of its nucleotide sequence into a complementary copy of
during the process called .
During this process, the enzyme,
separates the DNA strands.
One strand of DNA acts as the
from which nucleotides are assembled into a strand of RNA.
Each three letter sequence on the mRNA is called a .
The start codon is and the three stop codons are .
Once the mRNA leaves the nucleus, it goes to the to prepare for protein
synthesis, which is called .
During this process, a molecule brings the to the ribosome.
The amino acids are hooked together by bonds.
The tRNA is able to match up to the mRNA by the in its anticodons.
When the codon is reached, the chain is released into the .

a
Either the sperm cell or the egg cell has one copy of chromosome 21.
b
In a mistake in mitosis, the fertilized egg has two copies of chromosome 21.
c
In a mistake in meiosis, the fertilized egg has two copies of chromosome 21.
d
Either the sperm cell or the egg cell has two copies of chromosome 21.
Question 3
The picture shows a mutation that occurs when cells are exposed to UV radiation.
How can this mutation affect the new cells that are produced using this DNA? Select all that apply.
a
The new cells can become cancerous.
b
The new cells do not undergo mitosis.

Question 7
Read the passage "Superweeds" in the box.
SUPERWEEDS
Due to new technology, scientists have been able to alter the DNA in corn, soybeans, and cotton to make them resistant to the chemical herbicides used to kill weeds. Consequently, millions of acres of United States farmland have been regularly sprayed with herbicides, leading to the development of a herbicide tolerance in weeds. Producers must now use larger amounts of herbicides and find new, stronger chemicals to fight off the herbicide-tolerant weeds.
What was the initial factor that led to the development of herbicide-resistant weeds?
a
genetic engineering
b
artificial selection
c
genetic cloning
d
