DNA polymerases are capable of editing and error correction, whereas the capacity for error correction in RNA polymerases appear

s to be quite limited. Approximately one error occurs in every 104 to 105 nucleotide incorporated in RNA. Given that a single base error in either replication or transcription can lead to an error in the protein coded by the gene or mRNA. Please suggest a possible explanation for this striking difference.

Explanation:

DNA polymerase replicates the DNA supplied to all new cells produced while RNA polymerase drives DNA copy RNA synthesis. Unless corrected, error in DNA replication could result in the transmission of the error DNA to all next-generation cells.

Protein synthesis error will cause faulty copies of RNA and degraded proteins. To order to ensure the transfer of key genetic information to future generations of cells, failure to DNA replication must be corrected.

Describe the steps in making packaging and exporting a protein from a cell
irina [24]

<u>Answer:</u>

<em>The steps in making packaging and exporting a protein from a cell are listed below in the following points:</em>

  • <em>Protein is made from the Ribosomes.</em>
  • <em>These proteins are gathered in the endoplasmic reticulum. </em>
  • <em>From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.</em>
  • <em>The Golgi bodies modify the protein to suitable forms that can be absorbed.</em>
  • <em>Finally it is transported to all part of cells in our body.</em>

Explain by a series of statements or steps how a tree trunk gets wider.
Alex73 [517]

Answer:

A tree will get wider by the secondary growth of the cells. This happens when the cell growth of the cambia or lateral meristems causes them to elongate and become primary tissue.

The site below gives a detailed description of secondary growth.

Which of the following is a true statement about sexual vs. asexual reproduction? A. Asexual reproduction, but not sexual reprod
Afina-wow [57]

The correct answer is: B. In sexual reproduction, individuals transmit half of their nuclear genes to each of their offspring.

The main difference between sexual and asexual reproduction is that in sexual reproduction genetic material from two parents is combined, while in asexual reproduction produced offspring is genetically identical to the one parent. So, advantage of sexual reproduction is that produced unique organisms contribute to genetic diversity (variation is formed). But, comparing to asexual reproduction, sexual reproduction requires more energy and lasts longer.

Asexual reproduction is found in lower organisms and can be in different forms: budding, vegetative reproduction, fragmentation, spore formation.
