The right answer is indivisible.

The word atom comes from the Greek "atomos" which means indivisible, indivisible. It was therefore perfectly suited to the concept of the atom when it was developed by chemists in the early nineteenth century, ie as the smallest part of a pure body.

Now, we know that atoms are not indivisible, that we can pull out electrons, fission their nucleus, etc ... But the name has remained!

<span>J. J. Thomson’s experiment disproved the theory that an atom is indivisible.

Because his experiments proved that the atom contains smaller negative particles distributed in a large positive mass, concluding that the atom is not a solid uniform sphere.

Tryptophan synthase is one of the enzymes synthesized from the trp mRNA. In wildâtype E. coli, the trp mRNA has a short halfâlif
lidiya [134]

Answer:

Explanation:

we have three strains.

the first  is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.

Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.

in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.

What property of the DNA molecule explains the necessity for Okazaki fragments? DNA is antiparallel. DNA is a linear molecule. D
Arada [10]

Answer:DNA is antiparallel.

Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
