"Cell biologists have introduced radioactively labeled carbohydrates, fats and amino acids to living cells, allowed time for cel

l metabolism, and then separated the various cell organelles from the cytoplasm. The radioactive molecules were detected as part of various cellular compounds, however the visible cell structures appeared unchanged. This leads us to conclude that":

Answer:

The correct answer will be- the cell structures undergo repeated breakdown and formation.

Explanation:

The carbohydrates, fatty acids and amino acids are the three important bio-molecules which form the components of various cellular structures.

In the given question, the cell biologist radiolabeled these biomolecules and then observed the cellular structures after cell metabolism. He found that few cellular structures contained radiolabeled structures and few not. This showed that the cellular structures constantly undergo changes in their structures due to cellular metabolic reactions and are broken down and reformed.

Thus,  the cell structures undergo repeated breakdown and formation is the correct answer.

Given the mRNA sequence below, what would tRNA anticodons be in response? A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A
Lesechka [4]

Answer:

U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Explanation:

The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).

The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.

Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

A single change in the<br> DNA of the hemoglobin gene will cause
daser333 [38]

Answer:

A “mutation” changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.

Why are 4 H+ needed for every ATP synthesized and exported by mitochondria, even though only 3 H+ need to be translocated by the
kykrilka [37]

Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP
