  • 1

    It is the process of protein synthesis in which the genetic information encoded in mRNA is translated into a sequence of amino acids in a polypeptide chain.

    True

  • 4

    The 3 dimentional shape of tRNA molecule

    L-shaped

  • 5

    tRNA molecules have an __________ of three bases that binds to a complementary codon on mRNA.

    Anticodon

  • 6

    It acts as the binding site for the mRNA and tRNA

    Ribosome

  • 7

    It catalyze the peptide bonds of the polypeptide

    Ribosome

  • 8

    How long is the single RNA strand which consist a tRNA molecule?

    80 nucleotides long

  • 9

    The enzyme which provides a correct match between a tRNA and an amino acid.

    AMINOACYL-tRNA SYNTHETASE

  • 10

    Flexible pairing at the third base of a codon is called?

    Wobble

  • 11

    What allows some tRNAs to bind to more than one codon

    Wobble

  • 12

    A ribosome is composed of two halves

    Large subunit, Small subunit

  • 13

    Each subunit is made up of

    RNA molecules, Proteins

  • 14

    The subunit of ribosomes which binds to the mRNA

    Small subunit

  • 15

    It has binding sites for tRNAs and also catalyzes peptide bonds between amino acids.

    Large subunit

  • 16

    They facilitate specific coupling of tRNA anticodons with mRNA codons in protein synthesis

    Ribosomes

  • 17

    What are the 3 binding sites of ribosomes

    P site, A site, E site

  • 18

    How are the three binding sites arrange in a Ribosome?

    E-P-A

    It holds the tRNA that carries the next amino acids to be added to the chain.

    Aminoacyl site

    Complete name of E site

    Exit site

  • 24

    It is where discharged tRNAs leave the ribosomes

    730 amino acids

  • 27

    Only certain genes in a genome need to be expressed depending on:

    Cell specialism, Environment

  • 28

    They attach to the ribosomes

    mRNA

  • 29

    They carries its specific amino acid to the ribosome

    tRNA

  • 30

    They attach to free amino acids

    tRNA

  • 31

    Begins when initial portion of mRNA molecule bind tRNA in a ribosome

    Translation

  • 32

    Start signal is coded by what codon?

    AUG codon

  • 33

    Stop signal is coded by one of the following codon

    UAA codon, UAG codon, UGA codon

  • 34

    Polypeptide synthesis begins with the formation of an

    Initiation complex

  • 35

    The stage of translation which brings together mRNA, a tRNA with the first amino acids and two ribosomal subunits

    Initiation

  • 36

    During this stage, amino acids are added one by one to the proceeding amino acids.

    Elongation

  • 37

    Each addition in the stage of elongation involves a protein called

    Elongation factors

  • 38

    Elongation occurs in three steps:

    Codon recognition, Peptide bond formation, Translocation

  • 39

    In this stage, the ribosomes moves nucleotides along mRNA molecules.

    Translocation

  • 40

    They are recognized by release factors that release the newly made polypeptide form the ribosomes.

    Nonsense codons

  • 41

    What release the newly made polypeptide from the ribosome?

    Release factor

  • 42

    In what stage of translation do the nonsense codons are being recognized by release factors?

    Termination

  • 43

    The AUG start codon is recognized by what?

    Methionyl-tRNA

  • 44

    Three stages of building a polypeptide

    Initiation, Elongation, Termination

  • 45

    Read!!

    Done

  • 46

    The final stage of translation, also when the ribosome reaches a STOP codon

    Termination

  • 47

    What small protein attaches to the Stop codon?

    Release factor

  • 48

    It causes the whole complex to fall apart: the mRNA, the two subunits and the new polypeptide.

    Release factor

  • 49

    It consist of a series of information blocks called codons.

    Genetic code

  • 50

    They are a triplet of bases which encodes a particular amino acid.

    Codons

  • 51

    How many codons are there?

    64 codons

  • 52

    For how many amino acids can the codons translated with?

    20 amino acids

  • 53

    The first amino acid in all polypeptide

    Methionine

  • 54

    Different codons can be translate for the same amino acid, therefor the genetic code is said to be ___________.

    Degenerate

  • 55

    What carries the amino acids?

    tRNA

    It catalyze the peptide bonds of the polypeptide

    Ribosome

  • 8

    How long is the single RNA strand which consist a tRNA molecule?

    80 nucleotides long

  • 9

    The enzyme which provides a correct match between a tRNA and an amino acid.

    AMINOACYL-tRNA SYNTHETASE

  • 10

    Flexible pairing at the third base of a codon is called?

    Wobble

  • 11

    What allows some tRNAs to bind to more than one codon

    Wobble

  • 12

    A ribosome is composed of two halves

    Large subunit, Small subunit

  • 13

    Each subunit is made up of

    RNA molecules, Proteins

  • 14

    The subunit of ribosomes which binds to the mRNA

    Small subunit

  • 15

    It has binding sites for tRNAs and also catalyzes peptide bonds between amino acids.

    Large subunit

  • 16

    They facilitate specific coupling of tRNA anticodons with mRNA codons in protein synthesis

    Ribosomes

  • 17

    What are the 3 binding sites of ribosomes

    P site, A site, E site

  • 18

    How are the three binding sites arrange in a Ribosome?

    E-P-A

  • 19

    Complete name for P site

    Peptidyl site

  • 20

    Complete name for A site

    Aminoacyl site

  • 21

    It holds the tRNA that carries the growing polypeptide

    Peptidyl site

  • 22

    It holds the tRNA that carries the next amino acids to be added to the chain.

    Aminoacyl site

  • 23

    Complete name of E site

    Exit site

  • 24

    It is where discharged tRNAs leave the ribosomes

    Exit site

  • 25

    The length of mRNA molecules in mammals

    2200 nucleotides

  • 26

    How many amino acids in the average polypeptide

    730 amino acids

  • 27

    Only certain genes in a genome need to be expressed depending on:

    Cell specialism, Environment

  • 28

    They attach to the ribosomes

    mRNA

  • 29

    They carries its specific amino acid to the ribosome

    tRNA

  • 30

    They attach to free amino acids

    tRNA

  • 31

    Begins when initial portion of mRNA molecule bind tRNA in a ribosome

    Translation

  • 32

    Start signal is coded by what codon?

    AUG codon

  • 33

    Stop signal is coded by one of the following codon

    UAA codon, UAG codon, UGA codon

  • 34

    Polypeptide synthesis begins with the formation of an

    Initiation complex

  • 35

    The stage of translation which brings together mRNA, a tRNA with the first amino acids and two ribosomal subunits

    Initiation

  • 36

    During this stage, amino acids are added one by one to the proceeding amino acids.

    Elongation

  • 37

    Each addition in the stage of elongation involves a protein called

    Elongation factors

  • 38

    Elongation occurs in three steps:

    Codon recognition, Peptide bond formation, Translocation

  • 39

    In this stage, the ribosomes moves nucleotides along mRNA molecules.

    Translocation

  • 40

    They are recognized by release factors that release the newly made polypeptide form the ribosomes.

    Nonsense codons

  • 41
