10.12-10.14 Translation

Question 1

Ribosome(Mixture of protein and ribosomal RNA rRNA)

Answer 1

Ribosomes are the sites at which the genetic code is actually read by a cell. mRNA is like a dollar bill and ribosome is like a vending machine.

Question 2

tRNA

Answer 2

It translates from the language of nucleotides into the language of amino acids and proteins.

Question 3

tRNA

Answer 3

On the top of the tRNA is an amino acid. On the other end is a specific sequence of three nitrogenous bases(anti codon)

Question 4

The first amino acid is MET

Answer 4

The first triplet codon is AUG. So the anticodon is UAC.

Question 5

Anticodons

Answer 5

The matching pieces of the puzzle: a tRNA with a three bases that will pair with the condon sequence.

Question 6

Initiation of Polypeptide Synthesis

Answer 6

The mRNA, the first tRNA and the ribosomal subunits come together.

Question 7

Elongation

Answer 7

A succession of tRNAs add their amino acids to the polypeptide chain as the mRNA is moved through the ribosome, one codon at a time.

Question 8

Termination

Answer 8

The ribosome recognizes a stop codon. The polypeptide is terminated and released.

Question 9

Primary-Sequence

Answer 9

One amino acid covalently bonded to another and that one to another, in a single file.

Question 10

Secondary-Sheets and Spirals

Answer 10

Alpha helices and beta sheets held together by hydrogen bonds

Question 11

Tertiary

Answer 11

One folded amino acid chain held together by disulfide bonds

Question 12

Quaternary

Answer 12

Several folded amino acid chains (subunits) held together by hydrophobic interactions
