Transcription is the copy process of a segment of the DNA template strand to produce mRNA. The<u> blue</u> segment is DNA, and the<u> yellow </u>segment is mRNA.

<h3>What is transcription?</h3>

The first step before protein arrangement is to synthesize messenger RNA, mRNA.

Transcription is the synthesis of the messenger RNA, mRNA. This event occurs in the nucleus and uses fragments of DNA molecules to do it.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: the coding strand and the template strand.

The coding strand goes in direction 5' to 3',

The complementary strand -template strand- grows in direction 3' to 5'.

The template strand is the one that is going to be complemented by the mRNA. RNA polymerase is in charge of reading the original DNI strand for mRNA synthesis.

mRNA molecule grows complementing DNA base sequences. This is,

adenine ⇔ uracil

guanine ⇔ cytosine

thymine ⇔ adenine

<u>cytosine ⇔ guanine </u>

Once mRNA synthesis is over, the molecule leaves the nucleus to start the transcription process in the cytoplasm.

Answer:

The blue segment is DNA molecule

The yellow segment is mRNA molecule

1- DNA molecule

2- Separation of the DNI molecule into two strands and mRNA molecule growing.

3- mRNA molecule already synthesized and separated from DNA

If present, the ________________ allele will always be expressed as the phenotype.

k0ka [10]

Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.

How does electrocution cause rigid paralysis?

jeyben [28]

Answer:

Muscles are stimulated by electricity. The effect depends on the intensity of the current and the type of muscle it travels through.

The victim may be unable to let go of the source of the current, making the duration of the contact longer and increasing the severity of the shock.

When a current above 10 mA travels through extensor muscles, it causes a violent spasm. If the muscles affected are the hip extensors that lengthen the limbs away from the body, the victim may be propelled, sometimes many metres away!

Muscles, ligaments and tendons may tear as a result of the sudden contraction caused by an electric shock. Tissue can also be burned if the shock is lasting or the current is high.planation:
