Use the following to answer the questions below:
In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:
-Statements: (1) Ribosomes, which contain rRNA, serve as sites for protein synthesis.
(2) In genetic engineering, one of the functions of restriction enzymes is to cleave the double-stranded DNA of a circular plasmid.
(3) The nucleotide units within a nucleic acid are linked to each other through sugar-base bonds.

Question

Quizplus · Accepted Answer

Statement 1 is true because ribosomes do contain rRNA and are indeed the sites for protein synthesis. Statement 2 is also true as restriction enzymes are commonly used in genetic engineering to cut double-stranded DNA, including that of circular plasmids, at specific sequences. Statement 3 is false because nucleotide units within a nucleic acid are linked through phosphodiester bonds, not sugar-base bonds.
