If the sequence of bases on the mRNA codon is AUU, what would be the sequence of bases on the anticodon of the tRNA?
The sequence of bases on the anticodon of the tRNA is complementary to that of the mRNA codon. In the case of the mRNA codon AUU, the complementary anticodon would be UAA.
To determine the sequence of bases on the anticodon of the tRNA, we need to remember the complementary base pairing rules: A pairs with U (uracil) and G pairs with C (cytosine) in RNA.
Given that the mRNA codon is AUU, the complementary bases on the anticodon of the tRNA will be:
A -> U
U -> A
U -> A
Therefore, the sequence of bases on the anticodon of the tRNA would be UAA.
To determine the sequence of bases on the anticodon of tRNA, we need to follow the base pairing rules. In RNA, adenine (A) always pairs with uracil (U). Therefore, the complementary anticodon to the mRNA codon AUU would have the bases UAA.
Here's how you can arrive at this answer:
1. First, identify the mRNA codon. In this case, the codon is AUU.
2. To determine the anticodon, remember that the bases on the anticodon pair with the bases on the mRNA codon. The pairing is done with complementary bases: A pairs with U, C pairs with G, and G pairs with C.
3. So, for the codon AUU, the corresponding anticodon will have the bases UAA.
Therefore, the sequence of bases on the anticodon of the tRNA would be UAA.
Tetracycline is an antibiotic that blocks tRNA from entering the ribosome and associating with mRNA. If tetracycline were added to the cytoplasm of a eukaryotic cell, which types of proteins would be made?
If tetracycline blocks tRNA from entering the ribosome and associating with mRNA, protein synthesis would be disrupted. Without tRNA, the ribosome cannot properly translate the mRNA and synthesize proteins. As a result, the cell would not be able to make any proteins. Therefore, no specific types of proteins would be made in the cytoplasm of a eukaryotic cell when tetracycline is added.
Tetracycline is an antibiotic that blocks tRNA from entering the ribosome and associating with mRNA. If tetracycline were added to the cytoplasm of a eukaryotic cell, which types of proteins would be made?
a. No proteins will be made if tRNA cannot bind to mRNA
b. Only proteins that function is the cytoplasm of the cell
c. Only proteins that will be exported outside of the cell
d. Only proteins that will be inserted into a membrane
a. No proteins will be made if tRNA cannot bind to mRNA.
When tetracycline blocks tRNA from entering the ribosome and associating with mRNA, protein synthesis is disrupted. This means that the ribosome will not be able to properly translate the mRNA and synthesize proteins. Without the binding of tRNA to mRNA, the cell will not be able to produce any proteins, regardless of their cellular localization or function. Therefore, the correct answer is a. No proteins will be made if tRNA cannot bind to mRNA.
How do prokaryotes and eukaryotes differ in how they store genetic material?
a. Eukaryotes have RNA instead of DNA
b. Prokaryotes have RNA instead of DNA
c. Prokaryotes lack a true nucleus
d. Eukaryotes lack a true nucleus
c. Prokaryotes lack a true nucleus.
One major difference between prokaryotes and eukaryotes in how they store genetic material is the presence or absence of a true nucleus. In prokaryotes, such as bacteria, the genetic material, which is typically in the form of DNA, is not enclosed within a membrane-bound nucleus. Instead, it is found in a region called the nucleoid, which is not separated from the cytoplasm by a nuclear membrane. In contrast, eukaryotes, which include animals, plants, fungi, and protists, have their genetic material, consisting of DNA, stored within a membrane-bound nucleus. This compartmentalization allows for more complex regulation and organization of genetic material in eukaryotes. So, the correct answer is c. Prokaryotes lack a true nucleus.
