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 .

Question 4
Farmers across many centuries have used selective breeding (artificial selection) to enhance certain qualities in their crops. Which of the following qualities would most likely be selected for in breeding?
a
decreased nutrient composition
b
decreased harvest production
c
resistance to harmful pests
d
bioluminescence for attraction to fireflies
Question 5
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.
c
The new cells shrink because they lose water.
d
The new cells are produced with this mutation.
e
The new cells absorb water and become larger.
f
The new cells do not contain DNA with this mutation.
Question 6
How can this individual be identified?
a
normal male
b
male with Down syndrome
c
normal female
d
female with Down syndrome
Question 7
A child is born with cystic fibrosis, an inherited recessive disorder. No one in the family (on either side) for several generations is known to carry the gene or have the disorder. How can this be explained?
a
The genetic disorder formed from the mother's poor nutrition and prenatal care.
b
There was a mutation in the DNA, either in one of the gametes or the fertilized egg.
c
The child contracted the illness from another child when he was born.
d
The child developed the disorder when he was born; it is a result of a birth defect.
Question 1:
The RNA that carries amino acids to the ribosome during translation is called tRNA. To find the answer, you can review the process of translation and the different types of RNA involved.
Question 2:
To determine which table correctly describes the difference between DNA and RNA, you can compare the characteristics of both DNA and RNA. Look at the options given in the question and match them with the correct description of DNA and RNA.
Question 3:
This question requires you to fill in the blanks with the appropriate terms related to DNA and its processes. To answer this question, you can review the information provided in the question and use the word bank to find the correct terms to fill in the blanks.
Question 4:
To determine which quality would most likely be selected for in breeding, you can analyze the options given and think about which quality would be desirable for farmers in enhancing their crops. Consider the purpose of selective breeding and the qualities that would be beneficial for crop production.
Question 5:
To determine how the mutation can affect the new cells produced using this DNA, you can analyze the options given and think about the potential consequences of the mutation. Consider the effects of UV radiation on DNA and how mutations can impact cell function and behavior.
Question 6:
To identify the individual shown in the picture, you can analyze the characteristics of the individual and compare them to the options given. Consider the physical traits or features that may indicate a specific condition or syndrome.
Question 7:
To explain how a child is born with cystic fibrosis despite no known carriers in the family, you can analyze the options given and think about the possible explanations for the inherited recessive disorder. Consider the concepts of genetic inheritance, mutations, and the likelihood of a carrier being present even without a known family history.
