Let's go through your questions step by step:
-
Fill in the amino acid that corresponds to the given mRNA codon:
- UGG: This codon corresponds to the amino acid Tryptophan (Trp).
- GUA: This codon corresponds to the amino acid Valine (Val).
- LUXGA: This appears to be an incorrect codon; it should follow the standard format (3 letters). Please check this codon.
- CAC: This codon corresponds to the amino acid Histidine (His).
-
Given the DNA code, fill in the complementary mRNA codon and the corresponding amino acid:
- DNA code: CGT
- Complementary mRNA codon: GCA
- Amino Acid: GCA corresponds to Alanine (Ala).
-
All codons are 3 bases long. (This statement is correct.)
-
What is the base sequence for the mRNA "start codon"?
- The start codon is AUG.
-
All proteins begin with which amino acid?
- All proteins begin with the amino acid Methionine (Met), which is encoded by the start codon AUG.
-
Where in the cell does translation take place?
- Translation takes place in the ribosome (either in the cytoplasm or on the rough endoplasmic reticulum).
-
tRNA has an anticodon at one end that complements the mRNA codon and at the other end (it carries a specific amino acid).
-
There are different kinds of amino acids, (typically, there are 20 standard amino acids that make up proteins).
-
Amino acids are held together by peptide bonds.
-
Translation ends when the ribosome reaches a codon known as a stop codon (UAA, UAG, or UGA).
