Force-Time Relation

The force applied on an object is directly proportional to the square of the time, and also proportional to the time itself. This is represented by F = αt² + βt, where α and β are constants.

Constants α and β

The constants α and β are related to the initial force and the rate of change of force. The force is zero at time t = 0.

Unit of Force

The unit of force is Newtons (N).

Capacitance

Capacitance is a measure of a capacitor's ability to store an electrical charge. It is measured in Farads (F).

What are snRNAs?

Small nuclear RNAs (snRNAs) are involved in splicing, a crucial process that removes introns from pre-mRNA to create mature mRNA. They are part of the spliceosome, the molecular machinery responsible for splicing.

What are tRNAs?

Transfer RNAs (tRNAs) are small RNA molecules that carry specific amino acids to ribosomes during protein synthesis. They have a cloverleaf structure and act as adaptors, translating genetic code into protein sequences.

What is the role of ribosomes in protein synthesis?

In protein synthesis, ribosomes are the sites where amino acids are linked together to form proteins. Ribosomes consist of both ribosomal RNA (rRNA) and proteins.

What is the function of mRNA in protein synthesis?

mRNA carries genetic information from the DNA to the ribosomes to direct protein synthesis. This genetic code, in the form of codons (three-nucleotide sequences), instructs the sequence of amino acids in the protein.

How are genes linked to protein synthesis?

Genes are segments of DNA that contain the instructions for building specific proteins. Through transcription, the genetic information in DNA is copied into mRNA, and then translated into proteins by ribosomes.
