The diagram of a eukaryotic ribosome shown below contains several errors

Part A

Examine the diagram carefully, and identify each error. Select all that apply.

the number of ribosomal subunits is incorrect

the ribosome is moving in the wrong direction along the MRNA

the amino acid on the tRNA in the A site is incorrect

the terminal amino acid of the peptide is incorrect

the MRNA incorrectly contains Ts

the MRNA incorrectly contains adenines

small ribosomal subunit size is incorrect

the amino acids on the tRNA in the P site are incorrect

large ribosomal subunit size is incorrect

the anticodon sequence of the tRNA in the P site is incorrect

the tRNA incorrectly contains cytosines

Solutions

Expert Solution

1. TRUE
The number of ribosome subunits = 2
Prokaryotes = 50S + 30S
Eukaryotes = 60S + 40S

2. TRUE
The ribosome translocates along the mRNA in 5'-3' direction

3. TRUE
Codon = 3'-ACC-3'
Anticodon should be 5'-UGG-3'

4. TRUE
The N-terminal amino acid should be Met

5. TRUE
The mRNA contains Uracil in the place of Thymine

6. FALSE
The mRNA contains AUGC bases.

7. TRUE
Prokaryotes = 50S + 30S
Eukaryotes = 60S + 40S

8. TRUE
GCA = Ala

9. TRUE
Prokaryotes = 50S + 30S
Eukaryotes = 60S + 40S

10. TRUE
The tRNA does not contain Thymine

11. FALSE
The base composition of tRNA = AUGC

The energy level diagram of the hydrogen atom is shown the figure below. An atom generally has an electron in a given energy level, however, a transition may occur if the atom absorbs or emits a photon, or particle of light.Note: The energy of a photon can be written as \(E_{v}=h c / \lambda\) and the constants \(h c=1240 \mathrm{eV}-\mathrm{nm}\).1. In the Bohr model of the atom, energy is radiated whenA. an electron falls from an outer energy level to...
