carrying the genetic message from DNA in the nucleus to the ribosomes
|
Detailed explanation-1: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
Detailed explanation-2: -messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
Detailed explanation-3: -mRNA carries genetic information from DNA to ribosomes. Ribosomes are the site for protein synthesis. The process of translation takes place in ribosomes. Thus, the correct answer is option B.
Detailed explanation-4: -The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs. During translation, proteins are made using the information stored in the mRNA sequence. The mRNA attaches to a structure called a ribosome that can read the genetic information.
Detailed explanation-5: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
