A protein is made up of one or more amino acids linked together to form a chain. The building blocks of the protein are called amino acids. Amino acids are termed as residues if they release a hydrogen ion from the amine end or a hydroxyl ion from the carboxyl end, or both; a water molecule is released as a result of the formation of each amide bond.

Question

Chapter 12, Problem 1SQ

Summary Introduction

Concept introduction: A protein is made up of one or more amino acids linked together to form a chain. The building blocks of the protein are called amino acids. Amino acids are termed as residues if they release a hydrogen ion from the amine end or a hydroxyl ion from the carboxyl end, or both; a water molecule is released as a result of the formation of each amide bond.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: For a protein-coding gene, an mRNA molecule carries information from the gene to the ribosomes. Hence, option b. is the correct answer.

Explanation of Solution

Reasons for correct statement:

Option b. is given as “mRNA”.

Protein synthesis involved two main processes, namely transcription and translation. Transcription is the process of conversion of deoxyribonucleic acid (DNA) to messenger ribonucleic acid (mRNA). This is catalyzed by the process called transcriptase. These mRNA are protein-coding genes. They carry the information from the gene to the ribosome, where translation takes place. These mRNA are coded for protein and peptide sequences and synthesized. This forms the central dogma of molecular biology. Thus, mRNA carries genetic information from genes to ribosomes. Hence, option b. is the correct answer.

Reasons for the incorrect statement:

Option a. is given as “DNA”. DNA carries genetic information from one gene to another. A protein carries information from a gene to a ribosome; not DNA. Hence, option a. is incorrect.

Option c. is given as, “tRNA”. tRNA is transfer RNA. This carries the amino acids to the ribosome. Proteins carry information from gene to ribosome not tRNA. Hence, option c. is incorrect.

Option d. is given as, “rRNA”. rRNA is the ribosomal RNA that catalyzes the formation of a peptide bond. Proteins carry information from genes to ribosomes; not rRNA. Hence, option d. is incorrect.

Therefore, options a., c., and d. are incorrect.

Conclusion

Conclusion: mRNA carries genetic information from genes to ribosomes.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
