RNA- mRNA and tRNA

Question 1

How is RNA different to DNA?

Answer 1

-Pentose in RNA is ribose and in DNA is deoxyribose
-Organic base Uracil replaces thymine in RNA
-mRNA and tRNA are single stranded and DNA is double stranded

Question 2

What structure does mRNA have?

Answer 2

Linear

Question 3

What process is mRNA involved in?

Answer 3

Protein synthesis

Question 4

How is mRNA formed and where does it go?

Answer 4

Formed in the nucleus during transcription

Moves to the ribosome

Question 5

Where is tRNA found?

Answer 5

In the cytoplasm

Question 6

How many types of tRNA molecules are there?

Answer 6

At least 20 different types

Question 7

What shape are tRNA molecules?
What causes this?

Answer 7

Clover leaf

Due to hydrogen bonds between complementary bases

Question 8

What two areas does a tRNA molecule possess?

Answer 8

An anticodon on one end

A binding site at the other end

Question 9

What is the anticodon completely too?

Answer 9

The codon

Question 10

What is the differences between mRNA and tRNA?
(Big table)

Answer 10

-mRNA has a linear structure and tRNA had a clover leaf structure
-mRNA has codons aka mRNA triplets and tRNA has anticodons aka 3 unpaired bases
-mRNA has no Hydrogen bonds present but tRNA does have hydrogen bonds
-mRNA has no amino acid binding site but tRNA does
- mRNA involved in both transcription and translation but tRNA only involved in translation
-mRNA formed in nucleus and tRNA formed in cytoplasm

Question 11

How many amino acids can a tRNA molecule bind too?

Answer 11

Only one specific amino acid

Question 12

What does the mRNA in ribosome determine?

Answer 12

What tRNA binds
