A molecule of bacterial DNA introduced into a yeast cell is imported into the nucleus but fails to replicate with the yeast DNA.

Answer:

Initiator proteins.

Explanation:

DNA replication may be defined as the process of formation of daughter DNA strand from the template parental strand. Three main process of DNA replication are initiation, elongation and termination.

The bacterial DNA is fail to replicate in yeast cells because the DNA is not able to show initiation in yeast cells. Initiation process is important to start the DNA replication. The specific proteins and polymerase are required in different organism. There is problem in initiation proteins that fails to initiate  DNA replication.

Thus, the answer is initiator proteins.

A population that is isolated in a remote environment is still able to experience genetic variation How could genetic variation
goblinko [34]

A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.

Explanation:

The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.

Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.

It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.

During photosynthesis, the energy used to pump protons comes from ___________, whereas in cellular respiration it comes from ___
Annette [7]

During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.

<h3>What are the steps in photosynthesis?</h3>
  1. The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.
  2. The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).
  3. Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
  4. The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.

The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.
