Which of the processes are coupled (i.e. LINKED) in prokaryotic organisms but uncoupled (i.e. UNLINKED) in eukaryotic organisms?

Answer:

Transcription & translation (Ans. A)

Explanation:

Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.

In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.

gogolik [260]

Answer:

The correct answer is : The opponent process theory

Explanation:

The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.

The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.

For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.

Thus, the correct answer is : The opponent process theory

Which type of enzyme ensures that the correct base for growing the chain is aligned with the template chain? a. ligases b. prima
White raven [17]

DNA Polymerases type of enzyme ensures that the correct base for growing the chain is aligned with the template chain.

<h3>What is DNA Polymerase?</h3>
  • The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase.
  • These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.
  • DNA polymerase "reads" the pre existing DNA strands throughout this process to produce two new strands that are identical to the preexisting ones.
  • Deoxyribonucleotides, the components of DNA, are synthesized by DNA polymerase as its primary purpose.
  • The nucleotides and bases found on each strand of the original DNA molecule are paired to form the DNA copies.
  • This coupling always occurs in certain pairings, with cytosine and guanine constituting one pair and thymine and adenine forming the other.
  • RNA polymerases, on the other hand, create RNA from ribonucleotides that are either found in RNA or DNA.

What is the role of spinder fibers in mitosis?
olga_2 [115]

Answer:

pindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.
