Question

Select the description of mRNA. a.a three‑dimensional complex of ribonucleotides and proteins that assembles polypeptide chains b.a cloverleaf‑shaped structure of ribonucleotides that contains an anticodon and is attached to an amino acid c.a linear sequence of ribonucleotides transcribed from DNA that carries instructions for protein production d.a linear chain of three or more amino acids joined by peptide bonds

Answer 1

Answer:

C. mRNA is a linear sequence of ribonucleotides transcribed from DNA that carries instructions( in the form of codon) for protein production.

Explanation:

DNA is transcribed into mRNA with the help of enzyme known as RNA polymerase by the process called as transcription.

mRNA is a linear sequence of nucleotides complementary to the template strand of DNA, and these sequences contain information in the form of codon for the synthesis of protein.

Finally with the help of tRNA and ribosomes, mRNA codes for amino acids by the process known as translation, as tRNA brings amino acids while the synthesis of protein according to the codon in mRNA because tRNA contain anti-codons which are complementary to codon in mRNA.
