Question

Expressed Sequence Tags (ESTs) refers to :
(1) Genes expressed as RNA
(2) Polypeptide expression
(3) DNA polymorphism
(4) Novel DNA sequences

Answer 1

Answer is option "1"

Explanation:

• Expressed Sequence Tags are small amounts of DNA progression (for the most part 200 to 500 nucleotides long) that are created by sequencing it is conceivable that one of the two pieces of the deals qualities.
• The idea is to progression bits of DNA that address characteristics imparted in explicit cells, tissues, or organs from different living creatures and uses these "tags" to edge a quality out of a touch of chromosomal DNA by planning base genes.
• The test related to recognizing qualities from genomic groupings fluctuates among living beings and is reliant upon genome size just as the nearness or nonattendance of introns- - the mediating DNA successions interfering with the protein-coding arrangement of a gene.
• Expressed Sequence Tags(ESTs) are DNA sequences (genes) that are expressed as mRNA for protein synthesis.
• So, the right answer is option 1  'Genes expressed as RNA'.
