Question 1

Three differences between DNA and RNA

Answer 1

Unlike DNA, RNA uses the sugar ribose instead of deoxyribose.
RNA in signal stranded.
RNA contains Uracil in the place of Thymine

Question 2

Three types of RNA

Answer 2

Messenger RNA, Transfer RNA, and Ribosomal RNA

Question 3

Messenger RNA

Answer 3

Carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell.

Question 4

Transfer RNA

Answer 4

Type of RNA that carries each amino acid to a ribosome during protein synthesis

Question 5

Transcription

Answer 5

The process of copying a base sequence from DNA to RNA is known as transcription

Question 6

Where does transcription take place in the Eukaryotes

Answer 6

In the eukaryotic nucleus

Question 7

Two roles of RNA polymerase

Answer 7

It binds to DNA and separates the DNA strands

It then uses one strand of DNA as a template to assemble nucleotides into a complementary strand of DNA

Question 8

Ribosomal RNA

Answer 8

Type of RNA that combines with proteins to form ribosomes
