The correct option is A.
Light microscope can be used to view living cells while electron microscope can not be used to view living cells; it can only be used to view dead specimens.
Electron microscope can not be used to view live specimens because, the preparation process used to prepare specimens for viewing under this microscope will kill the specimen.

Description of a blue shark
Westkost [7]

The aerodynamic shape and lightness of the blue shark body allow it to move “elegantly” across the oceans. It exhibits countershading like many other sharks. The upper part is an indigo blue tone while the ventral and the sides are white.

It has a long caudal heterocercal fin. The second dorsal fin measures almost half the size of the first and its pectoral fins are unusually long compared to other sharks. Its eyes are large, its teeth are triangular, and it has a conical snout.

It reaches a length ranging from 3.8 to 4 meters and weighs about 240 kilograms. This species presents slight sexual dimorphism since the female tends to measure little more than 1 meter in comparison with the male.

Find the prokaryotic promoter sequences; Draw boxes around them, Circle the start codon. Then transcribe the following DNA seque
Degger [83]

Explanation:

The transcription is a process which transcribe the DNA into a molecule which could be read by the machinery to translate it into the proteins and that molecule is known as the mRNA molecule.

1.The mRNA molecule is transcribed by an enzyme called RNA polymerase which transcribe DNA in 5'to 3'direction that is DNA strand will be 3' to 5'direction therefore the strand with 3' to 5' will act as template strand.

2. The RNA polymerase binds at promoter region and there are two sequences in prokaryotes at -35 end which is TTGACA and at -10 end which is TATAAT.

3. The translation begins after the start codon which is AUG therefore proteins will be synthesized after AUG.

In the given question, both promoter sequence are present in the 5'to 3'strand

There are two start codon thus two polypeptides will be synthesized.

How are genes and protiens related
Luda [366]

Answer:

Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.
