Which of the following is NOT true of the plasma membrane?

siniylev [52]

Answer:

Option C. It is found only in a eukaryotic cell.

Explanation:

Plasma membrane is also called cell membrane. It is found in all cells of living organisms both unicellular and multicellular. It controls the amount of nutrients and wastes entering or leaving a cell. Due to permeability, the substances are easily pass through. Plasma membrane also act as boundary of animal cell.

<h2>Homologous</h2>

Explanation:

<em>Two or more species share a unique physical feature,</em> for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.
<em>The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.</em>

Use the double-stranded DNA molecule below to answer the following questions. The first pair of nucleotides (bolded) contains th

krok68 [10]

Answer:

The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.

In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.

Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.
