The statement 'messenger RNA is single-stranded, and serves as a copy of the DNA code for the ribosome' is correct. This molecule (mRNA) allows the flow of information from DNA to protein.
During gene transcription, a fragment of DNA called gene is used as a template to synthesize a complementary single-stranded RNA called messenger RNA (mRNA).
Subsequently, the mRNA travels to the ribosome where this molecule is used as a template to create a protein by a process called translation.
The linear order of triplet of nucleotide or codons in mRNA indicates the order of amino acids in the growing polypeptide chain.

Explanation:
A breast self-examination is a technique which allows an individual to examine the breast tissue for any physical or visual changes. By doing breast self-examination, an early detection of breast cancer can be done. Both men and women should perform a such examination at least once in a month.
The clinical breast examination is carried out to differentiate normal breast from a discrete breast mass. If a discrete mass is identified then evaluation is essential in all such cases to exclude breast cancer. This evaluation is based on the features of the clinical findings, the age of the woman, and her personal risk for breast cancer.
