Answer 1

Answer:

1)

The branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.

2)

The motion of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity; also, the rotation of a particle about a fixed point in space

STOP CODONS

There are 3 STOP codons in the genetic code - UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation. These codons are also known as nonsense codons or termination codons as they do not code for an amino acid.

The three STOP codons have been named as amber (UAG), opal or umber (UGA) and ochre (UAA). "Amber" or UAG was discovered by Charles Steinberg and Richard Epstein and they named it amber after the German meaning of the last name of their friend Harris Bernstein. The remaining two STOP codons were then named "ochre" and "opal" so as to maintain the "color names" theme.

During protein synthesis, STOP codons cause the release of the new polypeptide chain from the ribosome. This occurs because there are no tRNAs with anticodons complementary to the STOP codons.

Answer 2

Answer:

Thermodynamics:

Thermodynamics is the branch of physicsthat deals with heat and temperature, and their relation to energy, work, radiation, and properties of matter.

Rotationl motion:

The motion of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity; also, the rotation of a particle about a fixed point in space.

A stop codon:

In the genetic code, a stop codon is a nucleotide triplet within messenger RNA that signals a termination of translation into proteins.
