Question

Proteomes are analyzed using: a) only DNA sequencing b) 2D gel electrophoresis c) Southern blots d) ASO's Which of the following is true? a) Human genes are all unique and show no similarity to genes from other organisms. b) only 1% of human genes show a high degree of similarity to genes from other organisms. c) Many human genes show a high degree of similarity to genes from other organisms. Which of the following is true about open reading frames? a) Even short ORF'S always represent a gene. b) An ORF only requires a promoter sequence, nothing else. c) Locating ORF's is part of annotating a genome. d) All the above. Which of the following is true about transgenic plants? a) Transgenic corn is cultivated in the USA b) Can be made using Ti plasmid and plant tissue culture c) May have increased nutritional value d) All the above are true.

Answer 1

1 )Proteomics is the study of proteins and are analysed using 2D gel electrophoresis

2D gel electrophoresis (2DE) is used for purifying individual proteins based on their isoelectric points and molecular weights.

Southern blot is used to purify DNA not protein. DNA sequencing is also used to sequence DNA

Answer is B

2) An interesting observation is that 50% of all the protein-coding sequences in human DNA is similar sequences in other organisms.

So answer is D

3) orf is also called coding sequence . All the above statements regarding this are true

So answer is D

4) Answer is D

All statements are correct
