Answer: Proteins are made using DNA as a template. The DNA is turned into RNA, and the RNA is then turned into DNA.

A change in these nucleotides could end up making some part of the protein different. A single nucleotide change could be silent (no change in the protein) or could change a single amino acid (amino acids are the building blocks of proteins). If that was an important amino acid, the protein might not function at all! A silent change can occur because the same set of nucleotides sometimes makes the same final amino acid (for example, reading "gcc" "gca" "gcg" or "gct" nucleotides all mean "alanine" amino acid).

The deletion of a single nucleotide, or the addition of one, can change the entire sequence of amino acids that come after it! Nucleotides are read in sets of three, so this throws off how the DNA is read. If would be like turning "The brown fox jumps over the dog" into "The gbrow nfo xjump sove rth edo g". Completely different! All of the words are thrown off.

I know it is long but I hope it helped

Answer:

The new cells are the same as the previous ones, since they are the result of the mitosis process.

Explanation:

When we cut our skin, our brain sends information to millions of cells to take action and prevent this cut from putting us in danger. At that moment, the blood cells begin their work, supplying enough oxygen to stop possible bleeding and start the healing process. Then another group of cells swap out possible bacteria that may be trying to get into the wound. Last but not least, skin cells enter cell division and undergo mitosis, to generate new cells and create a new skin layer.

New cells are the same as old cells, as they are the result of mitosis. Mitosis is the process of cell division where one cell gives rise to two cells exactly the same as it.

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.
