Question
Which of the following statements is TRUE regarding transcription and translation? *1 pointDuring protein synthesis, translation occurs prior to transcription.During transcription, an mRNA molecule is created from the DNA molecule.During translation, a DNA sequence is used to synthesize an amino acid sequence.Translation takes place in the nucleus, while transcription takes place in the cytoplasm.
Solution
The true statement regarding transcription and translation is: "During transcription, an mRNA molecule is created from the DNA molecule."
Here's why:
-
"During protein synthesis, translation occurs prior to transcription." - This statement is FALSE. In protein synthesis, transcription always occurs before translation. Transcription is the process where the DNA sequence of a gene is transcribed into mRNA, which is then used in translation to produce a protein.
-
"During transcription, an mRNA molecule is created from the DNA molecule." - This statement is TRUE. Transcription is the process where the DNA sequence of a gene is transcribed into mRNA. This mRNA is then used in the process of translation to produce a protein.
-
"During translation, a DNA sequence is used to synthesize an amino acid sequence." - This statement is FALSE. During translation, an mRNA sequence (not DNA) is used to synthesize an amino acid sequence. The mRNA sequence is a copy of the DNA sequence of a gene, and it is this mRNA sequence that is read in translation to produce a protein.
-
"Translation takes place in the nucleus, while transcription takes place in the cytoplasm." - This statement is FALSE. Transcription takes place in the nucleus, where the DNA is located. The resulting mRNA then moves to the cytoplasm, where translation takes place to produce a protein.
