Question

structure number 7 is - a polypeptide chain (protein). transcription. a dna molecule. a nucleotide. question 10 the making of mrna based on the sequence of nucleotides in dna is called - transcription. dna replication. translation. gene regulation.

Explanation:

• Transcription: It is the process where an mRNA molecule is synthesized using a DNA template. The DNA sequence is copied (transcribed) into an mRNA sequence.
• DNA replication: This is the process of making an identical copy of the DNA molecule itself, not forming mRNA.
• Translation: It is the process where the mRNA sequence is used to synthesize a polypeptide chain (protein) at the ribosome.
• Gene regulation: Refers to the mechanisms that control whether a gene is expressed (turned on to make mRNA and protein) or not, not the direct synthesis of mRNA from DNA.

Answer:

transcription.
