In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.

Jobisdone [24]

Answer: d). UAG

Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.

From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.

Eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.

frutty [35]

Answer:

Both:

The start codon is often AUG

Eukaryotic cell only:

The larger subunit of the ribosome is 60s.
The ribosomes initially binds the 5' end of mRNA.

Prokaryotic cell only:

The ribosome is 70s
Translation occurs in the cytoplasm
There are multiple ribosome binding site

Explanation:

AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
Bacterial mRNA contain multiple ribosome binding sites.
