What is the type of mutation shown below?

• missense mutation

• non-sense mutation

• silent mutation

During translation, tRNA anticodons match to mRNA codons. Each tRNA molecule can carry one particular amino acid. The amino acids are joined to form a polypeptide. Number the tRNA anticodons from 1-4 in the order in which they should appear to match the codons in the mRNA strand.

• 1. LAC (methionine)

  2. GAC (leucine)

  3. AAG (phenylalanine)

  4. LUU (lysine)

• 1. AAG (phenylalanine)
     LAC (methionine)
     LUU (lysine)
     GAC (leucine)

• 1. LUU (lysine)
     GAC (leucine)
     LAC (methionine)
     AAG (phenylalanine)

Any error during the transcription or translation of genes can cause mutation.

True or False

• True

• False

CCU-GAG-GAG is a portion of a DNA sequiince that results in hemoglobin protein. What specific protein can mutate the Pro-Glu-Glu amino acid sequence that can cause sickle cell anemia?

AUG translates to methionine|
True or False

• False

• True

The information in the gene is transcribed to a complementary single strand called mRNA. For mRNA, Uracil is used instead of Adenine.
True or False

• True

• False

Which among the following were not stated by Gregor Mendel about the basic laws of genetics?

• Traits are inherited from one generation to another

• Some genes are dominant, some are recessive.

• There is a recomb nation of parental traits in offspring.

• All of the above

Since the nucleotide sequence of a strand is complementary to that of its partner strand, both strands will bear different genetic information.

True or False

• True

• F, both strands will bear the same genetic information.

Where did Miescher discover DNA?

• wound

• pus cells

• nuclein

• photo 51

Given the mRNA sequence 5'-AUGCGGGUCAGCCGC-3', what is the corresponding amino acid sequence?
