They are genetically identical because when the cell splits into the daughter cells, it makes an exact copy of DNA chromosomes, forcing the cells to be identical.

Vitamins A, D, E, and K are dependent upon carbohydratesproteinsfats for their absorption by cells.
daser333 [38]
False, the description is incorrect.

The only right answer is oil or lipid or fats. These lipid macromolecules are the only substance needed in order for these vitamins A, D E and K to be absorbed by the cell and be used in many cellular activities.

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.

A landslide has isolated a part of the cicada population from the main population. After a few generations, the new generations
umka2103 [35]
<span>The bottleneck effect is the cause of the sudden shift in the genetic information of the population. Due to the landslide, suddenly high number of the members of the main population died, and this caused genetic drift for reducing the variation in the existing generation, which is now widely different from the original one.</span><span />
