levacccp [35]

Answer:

C) binding to mRNAs and degrading them or blocking their translation

Explanation:

<u>miRNAs:</u>

miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.

They silenced mRNA by the following processes:

(1) Cleavage of the mRNA strand into pieces,

(2) stopping mRNA from translation into proteins by ribosomes.

(3) Shortening of mRNA poly(A) tail and destabilizing it.

In eukaryotic cells, ribosomes are found both free in the cytosol and attached to the endoplasmic reticulum (ER). Proteins produ
Natali [406]

Answer:

<h2>1. Protein synthesis on attached ribosomes:</h2><h2>Destination:  cell membrane. </h2><h2>One general function : to be a surface receptor.</h2><h2>2. On free ribosomes- destination:  cytosol </h2><h2>One general function: microfilaments.</h2>

Explanation:

Proteins are synthesized by the process known as translation. Translation occurs by ribosomes as they can be attached with endoplasmic reticulum or they can be free in the cytosol.

Protein is synthesized according to the sequence of nucleotide on mRNA.

Newly synthesized protein contain signals  sequence which targets then for their final destination.

1. ONE ultimate destination of a protein produced on an attached ribosome:  These proteins, after synthesis enter into ER and then according to the signal sequence, they reach to their final destination.

Example: cell membrane.

One general function of the protein -  to be a surface receptor

2. One ultimate destination of a protein produced on a free ribosome: cytosol

One general function of the protein: microfilaments
