Viruses cannot replicate by themselves, because they lack a lot of the cellular machinery to do so. This is why they have to invade a cell, and use the cells cellular machinery to help the virus replicate.

This is the reason they are not considered living.

The rough endoplasmic reticulum (RER) is is a series of flattened sacs connected to ribosomes. The Golgi Apparatus is an organelle composed of flattened stacked pouches known as cisternae.

In this case, the missing words indicate:

Specifically, this organelle is attached on the ROUGH ENDOPLASMIC RETICULUM (RER) which will help to modify and package the polypeptide product.

It puts it into a transport vesicle to be sent over to the GOLGI APPARATUS to add molecular tags and sort it, like a post office.

The RER is required for the production and secretion of different hormones and proteins.

The Golgi apparatus plays fundamental roles associated with the transport, modification, and packaging of proteins and lipids into vesicles, which are subsequently delivered to specific cellular destinations.

Both the RER and Golgi apparatus form part of the endomembrane system.

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.

kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4) tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

Why are chloroplasts found only in plant cells?

mr_godi [17]

Chloroplasts are only found in plant cells because it is the organelle that makes photosynthesis possible and it makes food for the plant cells as in it makes its own food and animal cells dont need them because animals eat other animals for that food
