fomenos

Answer:

Option (2) and (3).

Explanation:

Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.

Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.

Thus, the correct answer is option (2) and (3).

We covered transcription and translation in our lab this week. Below, you'll find several steps required for protein synthesis.
AlladinOne [14]

Answer:

The correct answer is :

  • The 2 strands of DNA separate
  • mRNA is built based on the DNA template
  • mRNA leaves the nucleus
  • tRNA brings an amino acid into the P site.
  • tRNA brings an amino acid into the A site.
  • tRNA leaves the P site and a peptide bond is formed between the amino acids.
  • The mRNA+attached tRNA shifts, moving the 6-tRNA from A site to the P site.
  • The entire mRNA strand is translated into amino acids and a polypeptide is formed.

Explanation:

Protein synthesis is a process that is made up of two distinct processes namely transcription and translation.

Transcription: this process include several steps where the segment of DNA which has information, copied into the new molecule called mRNA which acts as the template as it has information copied from the DNA to produce gene expression.

Translation: is the process includes several steps in which a peptide chain is formed from the mRNA with the help of tRNA and ribosomes.

The correct order of steps is given under the answer heading.
