Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
There are no aminoacyl-tRNAs that will go to the A site of the ribosome when UGA is the codon. Is this true of false?
Step by step
Solved in 3 steps
- The amino acid glycine is encoded by four codons: GGA, GGC, GGG, and GGU. Which of the following statements correctly explains this fact? The glycine anticodon contains the sequence CC, but the 5' base of the anticodon can pair nonspecifically with the 3' base of the codon. The glycine anticodon contains the sequence CC, but the 3' base of the anticodon can pair nonspecifically with the 5' base of the codon. Glycine tRNA has four anticodons, and the appropriate anticodon specifically pairs with the correct codon. There are four tRNAs for glycine, each of which has an anticodon that specifically pairs with the correct codon. all of the aboveChoose whether the statement is TRUE or FALSE "There are no aminoacyl-tRNAs that will go to the A site of the ribosome when UGA is the codon."Dystrophin is mutated in the disease, causing a codon to change from GGA to UGA. What is the consequence of this change? (
- Several experiments were conducted to obtain information about how the eukaryotic ribosome recognizes the AUG start codon. In one experiment, the gene that encodes methionine initiator tRNA (tRNAiMet) was located and changed; specifically, the nucleotides that specify the anticodon on tRNAiMet were mutated so that the anticodon in the tRNA was 5′ –CCA–3′ instead of 5′ –CAU–3′. When this mutated gene was placed in a eukaryotic cell, protein synthesis took place, but the proteins produced were abnormal. Some of these proteins contained extra amino acids, and others contained fewer amino acids than normal. Q. If the same experiment had been conducted on bacterial cells, what results would you expect?Several experiments were conducted to obtain information about how the eukaryotic ribosome recognizes the AUG start codon.

Correlate the number of codons for these three amino acids with this information.
- Sickle cell disease is caused by a so-called “point mutation" in the human B-globin gene. A point mutation is the result of a single base substitution in the DNA encoding a gene. The sickle cell mutation results in substitution of Val for Glu at position 6 in the B-globin protein. (a) Using the information in Figure 5.18 explain how a point muta- tion could change a codon for Glu to a codon for Val. (b) Do you expect the pI for the sickle cell B-globin to be higher or lower than the pl for wild-type B-globin? Explain.Explain The mRNA codon of valine is: GUC UGG CCA TTGIn how many cases in the genetic code would it NOT be possible to know the amino acid specified by a codon if only the first two nucleotides of the codon are known?
