The term 'Nuclein' for the genetic material was used by :
If there are 999 bases in an RNA that codes for a protein with 333 amino acids, and the base at position 901 is deleted such that the length of the RNA becomes 998 bases, how many codons will be altered?
A second's pendulum is mounted in a rocket. Its period of oscillation decreases when the rocket:
The contraceptive 'SAHELI'
In E. Coli, during lactose metabolism, the repressor binds to:
Two planets orbit a star in circular paths with radii $R$ and $4R$, respectively. At a specific time, the two planets and the star are aligned in a straight line. If the orbital period of the planet closest to the star is $T$, what is the minimum time after which the star and the planets will again be aligned in a straight line (at the initial position)?
Match the following RNA polymerases with their transcribed products: Column I (a) RNA polymerase I (b) RNA polymerase II (c) RNA polymerase III Column II (i) rRNAs (ii) tRNA (iii) hnRNA

A rocket is fired vertically upward with a speed of $v = \frac{v_e}{\sqrt{2}}$ from the Earth's surface, where $v_e$ is escape velocity on the surface of Earth. The distance from the surface of Earth upto which the rocket can go before returning to the Earth is: (given, the radius of Earth $R = 6400$ km)
The correction factor 'a' to the ideal gas equation corresponds to
A particle executes simple harmonic oscillation with an amplitude $A$. The period of oscillation is $T$. The minimum time taken by the particle to travel half of the amplitude from the equilibrium position is:
Out of the following functions, which represents SHM? I. $y = \sin \omega t - \cos \omega t$ II. $y = \sin^3 \omega t$ III. $y = 5 \cos\left(\frac{3\pi}{4} - 3\omega t\right)$ IV. $y = 1 + \omega t + \omega^2 t^2$
A body of mass $m$ is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass $m$ is slightly pulled down and released, it oscillates with a time period of $3\text{ s}$. When the mass $m$ is increased by $1\text{ kg}$, the time period of oscillations becomes $5\text{ s}$. The value of $m$ in kg is:
The incorrect method to synthesize benzaldehyde is:
Against the codon 5' UAC 3', what would be the sequence of anticodon on tRNA?
Bilaterally symmetrical and acoelomate animals are exemplified by
The phase difference between displacement and acceleration of a particle in a simple harmonic motion is:
