Chapter 13, Problem 1MC
Summary Introduction

Introduction: Ribonucleic acid (RNA) is a polymer of nucleotides, which is directed by the DNA for the synthesis of proteins. It is made up of ribose sugar and nitrogenous bases, namely adenine, guanine, cytosine, and uracil. RNA is structurally similar to DNA but differs on the basis of sugar, strand, and nitrogen base.

Answer to Problem 1MC

Correct answer: Option b. “messenger RNA”.

Explanation of Solution

Reason for the correct answer:

Option b. is given as “messenger RNA”.

Messenger RNA (mRNA) functions as an information carrier from DNA in the nucleus to the ribosome in cytoplasm of the cell. This information is used by the cell to direct the synthesis of proteins. Group of three bases in mRNA is called codons that specify which amino acid will be incorporated into a protein.

Hence, option b. is correct.

Reasons for incorrect answers:

Option a. is given as “ribosomal RNA”.

Ribosomal RNA is responsible for the production of ribosomes at which polypeptide chains are formed during translation. Hence, option a. in incorrect.

Option c. is given as “transfer RNA”.

Transfer RNA transfers the amino acid to the ribosomal unit in translation process by which the information in mRNA is translated into protein molecules. Hence, option c. is incorrect.

Option d. is given as “noncoding RNA”.

Non-coding RNA is transcribed from DNA, but is not translated into proteins.

Hence, option d. is incorrect.

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

Conclusion

Messenger RNA carries the genetic information from DNA to the cytoplasm which is then used for protein synthesis.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
