To which organelle does a C-terminal signal peptide sequence of the four amino acids KDELdirect peptides?
Fofino [41]

Answer:

Endoplasmic reticulum.

Explanation:

Protein synthesis, sorting and transport is the important mechanism for the synthesis of protein in the body and the transport of the protein to its specific site or organ. The protein must reaches to its final destination for its proper functioning.

KDEL ( K- leucine, D is aspartic acid, E is glutamic acid and L is lysine ) is the stretch of a specific amino acid that are responsible for the protein molecule to target at its specific site. KDEL is specific for the transport of peptides to the endoplasmic reticulum.

Thus, the correct answer is option (A).

What is the role of RNA polymerase?
juin [17]
<span> RNA polymerase is commonly know as DNA-dependent RNA polymerase. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. It is found in the core of eukaryotic cells. One of which combined rRNA in the nucleolus while the rest of the chemical blends other RNA in the nucleoplasm, some portion of the core yet outside the nucleolus.</span>

Nadusha1986 [10]

Answer:

The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:

Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.

These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.

nikitadnepr [17]

Answer:

Meiosis and Genetic Variation.

Explanation:

When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.

When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.

In sexual reproduction, two gametes unite to produce an offspring. But which two of the millions of possible gametes will it be? This is likely to be a matter of chance. It is obviously another source of genetic variation in offspring. This is known as random fertilization.
