Answer:

45. B. Ribosomes

46. C. To bring the DNA message to the ribosome

47. D. Anticodon; UGA​

Explanation:

45. rRNA stands for ribosomal RNA. It is an important component of all ribosomes. It is non-coding RNA meaning it does not produce a protein. It is a ribozyme (an RNA with enzymatic activity) which carries out protein synthesis in ribosomes.

46. mRNA stands for messenger RNA. It is transcribed from DNA. After transcription, it goes to the ribosome where it is translated into protein.

47. tRNAs posses anticodons that are complementary to RNA codons. In RNAs, A pairs with U, and G pairs with C.

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate          (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

<span><span>Mitosis is the process in which cells divide to form new cells. The cell that is being described under the microscope is already in the Anaphase stage in mitosis.

Anaphase is the process in which two sister chromatids separate and move to opposite poles of the cell. These two sister chromatids contain identical copies of DNA that are joined at the middle called centromere. The chromosomes are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two separate poles. The mitotic process then proceeds to the Telophase.</span>

Answer:

A recessive autosomal allele is a heterozygous pair.

Explanation:

they have one mutated gene (recessive gene) and one normal gene (dominant gene) for the condition.

I would say you're best choice is E or F, but I can't remember right now. Its been a bit since my gene mutation module. Sorry I can't help more!
