Answer:

The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.

Explanation:

Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.

Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.

These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.

Thus, rRNA plays an important role during translation (protein synthesis) of mRNA.

Which phase of cell division is shown? O prophase O anaphase telophase O metaphase

AnnyKZ [126]

Answer: I don't have the picture you're looking at, but I can try to give you some clues to help you out.

Prophase is where the chromatids enter the cell and the chromosomes attach to the spindle fibers in the cell.

Metaphase: all of the chromosomes line up in the center of the cell (I use this trick I made up to remember this one: The chromosome will have Met the teacher's expectations when they line up in the center of the cell.)

Telophase: is where the sister chromatids go to opposite sides of the cell right before they split

Anaphase is when they finally split and are now classified as two different cells. One parent cell and one daughter cell.

I hope this helps you to solve your problem!

What is a lipid and what functions does it serve?

Sedaia [141]

Lipid - any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.

Its plays the role of storing energy or forming cell membranes alone.

During transcription, enzymes bind to a molecule of DNA. Then, the enzymes unwind and separate the DNA's double helical strands.

stich3 [128]

MRNA or messenger RNA. As the central dogma of biotech goes, DNA is transcribed to mRNA which is translated to tRNA, after which the amino acids form peptide bonds and form proteins. So when you see transcription, the first thing you think of is DNA to mRNA.

If an area is in the 50+ dBZ range, what atmospheric pressure conditions could the area be experiencing?

monitta

The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.

Explanation:

dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object to the return of a droplet of rain with a diameter of 1 mm.

dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.

Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.

Therefore the atmospheric pressure conditions differs from rains to hails.
