Question

if the dna reads agcttacatgcc, the complementary rna strand is:

• ucgaaugucggu
• tcgaatgtacggt

cancer may result from *

• beneficial mutations
• deletion mutations
• silent mutations
• all of the above

Explanation:

Complementary RNA strand synthesis

Using the DNA Base Pairing knowledge point

• DNA template: AGCTTACATGCC
• RNA pairing rules: A pairs with U, T pairs with A, C pairs with G, G pairs with C
• Complementary sequence: UCGAAUGUCGGU

Causes of cancer development

Using the Cancer Biology knowledge point

• Cancer arises from uncontrolled cell division caused by genetic mutations.
• Deletion mutations can disrupt tumor suppressor genes, leading to cancer.
• Beneficial mutations do not cause cancer, and silent mutations do not alter protein function.

Answer:

Question 1

• UCGAAUGUCGGU (Correct answer)
• TCGAATGTACGGT

Question 2

• beneficial mutations
• deletion mutations (Correct answer)
• silent mutations
• all of the above
