Q

How many strands does the structure of an RNA has?

A

One strand.

2
Q

Does the RNA have the same nitrogenous bases as the DNA?

A

No, Uracil replaces Thymine.

3
Q

What are the three types of RNA?

A

mRNA, tRNA, and rRNA.

4
Q

What is the function of the mRNA?

A

It carries out messages directly from the DNA in the nucleus to the cytoplasm during protein synthesis.

5
Q

What is the triplet nucleotides of mRNA called?

A

They are called Codons.

6
Q

What is the tRNA shaped like?

A

It is shaped like a coverleaf.

7
Q

What is the function of a tRNA?

A

It carries Amino Acids to mRNA at the ribosome in order to form a polypeptide.

8
Q

What is the triple nucleotide in tRNA called?

A

It is complementary to that of mRNA and are called Anticodons.

9
Q

What is the function of rRNA?

A

It is structural and along with proteins, it makes up the ribosomes.
