In functional genomics, biologists use sequence information to identify the functions of various parts of genomes. Which of the
k0ka [10]

Answer:

E: specific proteins that are made by a cell under particular conditions

Explanation:

It is only specific proteins that are made by a cell under particular conditions can't be obtained from a genome sequence. In order to get information about this protein we need proteomics.

Genome sequence gives us an idea of nucleotide sequence of DNA and RNA molecules not proteins. Regulatory sequences such as promoters, enhancers, insulators, UTRs etc. all are a part of genome, rRNA genes are part of genome sequence too, non coding repetitive repeats and intron regions are also a part of genome sequence itself so option A, B & D are incorrect. Option C is also incorrect because amino acid sequence of  proteins can also be determined by genome sequences because each nucleotide triplet which is known as codon refers to a specific amino acid. Option E is correct because by genome sequence we can easily get to know about amino acid sequence but not about specific protein which is synthesized at a particular condition.
