Expressed Sequence Tags (ESTs) refers to
Expressed Sequence Tags (ESTs) refers to
All genes that are expressed as proteins.
All genes whether expressed or unexpressed.
Certain important expressed genes.
All genes that are expressed as RNA.
The Correct Option is D
Solution and Explanation
ESTs are short DNA sequences derived from the complementary DNA (cDNA) of the messenger RNA (mRNA) molecules. They represent portions of expressed genes, providing insight into which genes are being actively transcribed and translated into proteins within a specific cell or tissue. ESTs have been used for gene discovery, expression profiling, and mapping genes to specific chromosomal locations.
Therefore, The correct option is (D): All genes that are expressed as RNA.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Human Genome Project
The Human Genome Project was an international research effort designed to map out the DNA sequence of an entire human genome. It was the first undertaking of its kind and took over a decade to complete. The goal of the Human Genome project was to sequence and identify the entire Human genome. And then store the entire genome information in a database. The Human Genome Project required improvement tools for data analysis.
The Human Genome Project (HGP) was an international, collaborative research program whose goal was the complete mapping and understanding of all the genes of human beings. All our genes together are known as our "genome."
Goals of the Human Genome Project
The HGP set out to establish the following goals:
- First, to identify all the approximately 20,000-25,000 genes that make up the human DNA.
- Map out the genome sequences of the 3 billion chemical base pairs that comprise the human DNA.
- Ensure the storage of the derived information in genome sequence databases.
- Optimize the tools required for the data analysis process.
- Handle the ethical, legal, and social issues (ELSI) that may arise during the project.
The shotgun phase of the Human Genome Project itself consisted of three steps:
- Obtaining a DNA clone to sequence
- Sequencing the DNA clone
- Assembling sequence data from multiple clones to determine overlap and establish a contiguous sequence
Impact of Human Genome Research
The Human Genome Project will entirely reshape the approach to all biomedical research as well as therapeutic and preventive health care. The development in fields like bioinformatics and biostatistics will allow for better pattern detection and analysis of genetic disorders.
