Question

Once researchers identified DNA as the molecule responsible for transmitting heritable traits, they asked how information was transferred from the DNA in the nucleus to the site of protein synthesis in the cytoplasm. Which of the following statements correctly describes the mechanism of information transfer in eukaryotes that accomplishes this task?
A) Transfer RNA takes information from DNA directly to a ribosome, where protein synthesis takes place.
B) Histone proteins in the chromosomes transfer information from the nucleus to the ribosome, where protein synthesis takes place.
C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
D) DNA from a single gene is replicated and transferred to the cytoplasm, where it serves as a template for protein synthesis

Answer 1

Answer:

C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.

Explanation:

DNA transfers the heredity information from parents to the offspring, via central dogma. DNA transcripts its information into messenger RNA, inside the nucleus via RNA polymerase and addition of base pairs.

This transcript of RNA carries the information encoded on it. It translates its information into proteins in the cytoplasm, According to the mRNA sequences the amino acid codons are created that form the specific peptides. This is how information is transferred from DNA in the nucleus and then to the cytoplasm.
