Question 0

What could happen if an antibody molecule had an amino acid in the wrong place?

Answer 0

This could end up in the antibody molecule being in the wrong shape and therefore unable to work properly.

To replace thymine.

Question 17

What is used to make the mRNA?

Answer 17

Nucleotides

Question 18

How do nucleotides know where to go? :(

Answer 18

They are attracted to their complimentary bases! ;)

Question 19

Once the mRNA is made, where does it go?

Answer 19

It passes through the nuclear membrane through a nuclear pore into the cytoplasm.

Question 20

In the DNA, what is a set of 3 bases called?

Answer 20

Triplet code.

Question 21

Answer 21

In the nucleus of a cell.

Question 22

Where does translation take place?

Answer 22

In the cytoplasm.

Question 23

What is the enzyme that reads the mRNA?

Answer 23

Ribosome

Question 24

How many condons can be fitted on to the ribosome at any one time?

Answer 24

2

Question 25

What is attracted to the condons attached to the ribosome?

Answer 25

Transfer RNA = tRNA

Question 26

What part of the tRNA is attracted to the condon?

Answer 26

The anticodon that has the correct sequence of complimentary base pairs.

Question 27

Why must the tRNA be specific to the curtain condon?

Answer 27

The tRNA has amino acids attached which must be sucured in the correct place.

Question 28

What happens once the condons are attached to the tRNA.

Answer 28

Once the condons are attached to the the anti condons the amino acids attached to the tRNA they form a peptide link.

Question 29

What happens to the tRNA after they have given up their amino acid?

Answer 29

They go to find another amino acid.

Question 30

How does the process know when to stop?

Answer 30

There is a codon that has a code that tells it to stop.

Question 31

What happens to the amino acids?

Answer 31

They form a polypeptide which joins with other polypeptides to make a protein.
