Question

1. all of the following statements about translation are true except:

a) the polypeptide or protein chain is released when the termination (stop) codon is read.
b) there is a transfer of information from the dnas base sequence into the complementary base sequence of mrna (codon) that specifies a specific polypeptide/protein.
c) trna (anticodon) transports an amino acid to the mrna strand and recognizes a mrna molecule (codon)
d) the ribosome moves the mrna strand along as each codon is read sequentially

1. sequences of three bases found in messenger rna (mrna) are called _. a) anticodons

b) deoxyribose sugars
c) codons
d) ribosomes
e) amino acids

Explanation:

For question 22, option b describes transcription (information transfer from DNA to mRNA) not translation. In translation, mRNA is used to make a polypeptide. For question 23, sequences of three - bases in mRNA are called codons. Anticodons are on tRNA, deoxyribose sugars are part of DNA, ribosomes are the sites of protein synthesis, and amino acids are the building blocks of proteins.

Answer:

1. B
2. C
