Activation energy of any chemical reaction can be calculated if one knows the value of:
DNA or RNA segment tagged with a radioactive molecule is called:
DNA-dependent RNA polymerase catalyses transcription on one strand of the DNA which is called the?
An n-p-n transistor is connected in a common emitter configuration (see figure) in which collector voltage drop across load resistance ($800\ \Omega$) connected to the collector circuit is $0.8\text{ V}$. The collector current is:
The half-life of a radioactive isotope $X$ is 20 years. It decays to another element $Y$ which is stable. The two elements $X$ and $Y$ were found to be in the ratio 1:7 in a sample of a given rock. The age of the rock is estimated to be:
Removal of RNA polymerase III from nucleoplasm will affect the synthesis of:
The ovary is half inferior in :
Two simple harmonic motions of angular frequency $100\text{ rad s}^{-1}$ and $1000\text{ rad s}^{-1}$ have the same displacement amplitude. The ratio of their maximum acceleration will be:
In the process of transcription in Eukaryotes, the RNA polymerase I transcribe -
The lac Operon consists of:
What initiation and termination factors are involved in transcription in prokaryotes?
Which of the following statement is correct regarding the process replication in E. coli?
What is false for GIFT?
A sequence of how many nucleotides in messenger RNA make a codon for an amino acid?
Select the correct option: Direction of RNA synthesis | Direction of reading of the template DNA strand
The decay constant of a radio isotope is $\lambda$. If $A_1$ and $A_2$ are its activities at times $t_1$ and $t_2$ respectively, the number of nuclei which have decayed during the time $(t_1 - t_2)$ is:
The incorrect statement among the following is:
During transcription, the DNA site at which RNA polymerase binds is called:
Expressed Sequence Tags (ESTs) refers to:
The activity of a radioactive sample is measured as $N_0$ counts per minute at $t=0$ and $N_0/e$ counts per minute at $t=5$ min. The time (in minute) at which the activity reduces to half its value is:
