Protein synthesis

Question 1

The larger units of ribosome contains three binding sites

Answer 1

A (aminoacyl) site
P (peptidyl) site
E (exit) site

Question 2

The role of the ribosomes is:

Answer 2

• make sure the read in successive
• nonoverlapping groups of nucleotides

Question 3

Codon

Answer 3

Each non-overlapping group of the 3 nucleotides

Question 4

Reading frames

Answer 4

Three letter words

Question 5

Anti-codon:

Answer 5

They make up the loop. Three nucleotides that base pair with anti-codons. in transfer tRNA

Question 6

CCA sequence:

Answer 6

The 3’ of hydroxyl group is the site for the amino acid corresponding to attach to eachother

Question 7

Aminoacyl tRNA synthetase

Answer 7

Connect specific amino acids to tRNA molecules. They are responsible for translating the codon sequence to amino acid.

Question 8

tRNA w/o amino acid

Answer 8

uncharged

Question 9

tRNA w/ amino acid

Answer 9

charged

Question 10

The smaller subunit of the ribosome

Answer 10

encodes the start codon AUG

Question 11

There are …..amino acids that are created from …..codons

Answer 11

20 amino acids
64 codons
The reason that is because there is redundancy

Question 12

The steps for translation are:

Answer 12

Initiation: The AUG codon is recognized and met established as the first amino acid

Elongation: Amino acids are added 1 by 1 through trna transferring amino acids to the A site

Termination: The addition of amino acids stops and when the ribosomes encounter a stop codon
