Common Questions and Answers from Pearson DNA and RNA Workbooks

Q1: What is the basic structure of DNA?

A: DNA is a double helix consisting of two strands of nucleotides. Each nucleotide contains a sugar (deoxyribose), a phosphate group, and a nitrogenous base (Adenine, Thymine, Cytosine, Guanine). The strands are held together by hydrogen bonds between complementary bases (A pairs with T, G pairs with C).

Q2: How does RNA differ from DNA?

A: RNA differs from DNA in several ways: - RNA contains ribose sugar instead of deoxyribose. - RNA is usually single-stranded, whereas DNA is double-stranded. - RNA has Uracil (U) instead of Thymine (T). - RNA plays a role in protein synthesis, while DNA primarily stores genetic information.

Q3: Describe the process of DNA replication.

A: DNA replication is a semi-conservative process where each original strand serves as a template for a new complementary strand. The process involves: - Initiation at specific origins of replication. - Unwinding the DNA helix by helicase. - Complementary base pairing facilitated by DNA polymerase. - Formation of two identical DNA molecules, each with one original and one new strand.

Q4: What is transcription, and why is it important?

A: Transcription is the process of synthesizing RNA from a DNA template. It is essential because it converts genetic information stored in DNA into a messenger RNA (mRNA) molecule, which then guides protein synthesis during translation.

Q5: Explain the roles of different types of RNA in protein synthesis.

• mRNA (Messenger RNA): Carries genetic information from DNA to the ribosome.
• tRNA (Transfer RNA): Brings amino acids to the ribosome during translation.
• rRNA (Ribosomal RNA): Forms the core of the ribosome's structure and catalyzes protein synthesis.

Q6: What are mutations, and how do they affect genetic information?

A: Mutations are changes in the DNA sequence. They can be: - Point mutations (single nucleotide change) - Insertions or deletions (adding or removing nucleotides) Mutations can lead to altered proteins, which may cause genetic disorders or beneficial traits, depending on their nature and location.
