Question

1. if the sequence of nitrogenous bases in one strand of dna is gta - gca, the sequence of bases on its complementary rna strand would be ________. a) cau - cgu b) cat - cgt c) gau - gcu d) gat - gct e) acg - att 25. some antibiotics inhibit trna from delivering amino acids to the ribosome. what process cannot be completed? a) transcription b) mitosis c) replication d) translation

Explanation:

For question 24, in transcription from DNA to RNA, adenine (A) in DNA pairs with uracil (U) in RNA, thymine (T) in DNA pairs with adenine (A) in RNA, guanine (G) pairs with cytosine (C), and cytosine (C) pairs with guanine (G). Given DNA sequence GTA - GCA, the complementary RNA sequence is CAU - CGU.
For question 25, translation is the process where tRNA delivers amino - acids to the ribosome to build a polypeptide chain. If tRNA is inhibited from delivering amino acids to the ribosome, translation cannot be completed.

Answer:

1. a) CAU - CGU
2. d) translation
