Question 8
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 or have the disorder. How can this be explained?

a
The child contracted the illness from another child when he was born.
b
The genetic disorder is recessive, and can be carried by heterozygous individuals without ever being realized or identified.
c
The child developed the disorder when he was born; it is a result of a birth defect.
d
The genetic disorder formed from the mother's poor nutrition and prenatal care.

Answer 1

Here are the answers to your questions:

Question 1: Which sugar is found in RNA?
Answer: c - ribose

Question 2: The table below shows the percentages of bases in a DNA sample. How much Adenine (A) should you expect to find in the sample?
Answer: b - 33%
(Note: In DNA, the amount of adenine equals the amount of thymine, and the total must equal 100%. So if A + T + C + G = 100% and A = T, then we can deduce the percentages.)

Question 3: Watson and Crick (with Franklin's help) were the first to suggest that DNA is a_____.
Answer: b - double helix

Question 4: Assume that two strands of DNA have been separated and that the base sequence on one strand is AGCC. What is the sequence of bases on the complimentary strand of DNA?
Answer: b - TCGG
(A pairs with T and C pairs with G.)

Question 5: What is the main goal of the central dogma?
Answer: a - To create proteins to carry on body functions.

Question 6: Why is tRNA called "transfer" RNA?
Answer: d - It carries/transfers a specific amino acid to the ribosome during protein synthesis.

Question 7: Structure X includes a deoxyribose sugar, a phosphate group, and a nitrogenous base. What is this structure called?
Answer: b - nucleotide

Question 8: A child is born with cystic fibrosis, an inherited recessive disorder. How can this be explained?
Answer: b - The genetic disorder is recessive, and can be carried by heterozygous individuals without ever being realized or identified.

Question 9: Match the DNA key terms to their correct definition.

1. genetic material: c - substance containing the genetic information of a cell
2. adenine: b - one of four nitrogenous bases found in DNA and RNA; pairs with thymine or uracil
3. base pairing: a - principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine
4. cytosine: i - one of four nitrogenous bases found in DNA and RNA; pairs with guanine
5. guanine: k - one of four nitrogenous bases found in DNA and RNA; pairs with cytosine
6. thymine: g - nitrogenous base found in DNA but not in RNA
7. frameshift mutation: j - mutation that shifts the “reading frame” of the genetic message by inserting or deleting a nucleotide
8. mutagen: f - chemical or physical agents in the environment that interact with DNA and may cause a mutation
9. mutation: d - change in the genetic material of a cell
10. point mutation: e - gene mutation in which a single base pair in DNA has been changed
11. polyploidy: h - condition in which an organism has extra sets of chromosomes

Question 10: Which correctly identifies each type of mutation in the diagram?
Answer: (The question does not provide the specific mutations shown in the diagram; however, based on standard definitions, the answer would depend on identifying them based on the described types.)
If we refer to typical definitions:

• Deletion (removing a nucleotide)
• Insertion (adding an extra nucleotide)
• Substitution (replacing one nucleotide with another)

You would need to visualize the diagram or additional context to choose one of the options (A, B, C, D). Please provide the diagram details if you'd like a specific answer.
