Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.

The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.

NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3' Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3' The two primers above have the melting

CaHeK987 [17]

Answer:

Short answer is primers are partially complementary.

Explanation:

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'

Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'

When we write reverse primer 5' to 3' we can easily see that

3'-TTGGCCAATGG---5' is complementary to the forward primers'

5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.

Consider the scenario in which Mutants A and B are grown in a medium that contains His, but does not contain Trp. For this scena

solmaris [256]

Answer: Attached below is the missing part of your question

answer

Mutant A

1) Requires tryptophan in the growth medium or from a donor mutant

2) Must form nanotubes to obtain it's required amino acid in this scenario:

Mutant B

1) Requires histidine in the growth medium or from a donor mutant

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario:

Explanation:

Mutant A ( Over produces His and cannot produce Trp )

1) Requires tryptophan in the growth medium or from a donor mutant ; This is because the Mutant is an auxotroph for tryptophan.

2) Must form nanotubes to obtain it's required amino acid in this scenario:

This is because growth medium of the mutant is supplemented with histidine

Mutant B ( cannot produce His and overproduces Trp )

1) Requires histidine in the growth medium or from a donor mutant :

This is because Mutant B lacks the biosynthetic pathways necessary for histidine production

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario: because the Mutant cell can easily take up the required amount of Histidine from its surroundings.
