Describe the direction of DNA replication. Why is that important?
Sever21 [200]

Answer:

DNA replication is the process by that DNA make a copy to the cell division.

Explanation:

  • DNA replication is the double structure to the DNA molecule,it is biological process.
  • DNA replication molecule the serve that template for the production to referred conservative replication.
  • DNA replication occurs living the biological property of division and they performed complementary stand.
  • DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
  • DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
  • DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
  • DNA replication is the basis of single strand to 3 prime and 5 prime  end, these refer to the carbon atom in the chain attaches.
  • DNA replication allow the strand to the one another strand to used in partner strand.
  • DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.

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.
