Answer:

ATP, Mitochondria, Cellular respiration.

Explanation:

The Krebs cycle of, cellular respiration, in the mitochondria results to the an accumulation of protons in the inter-membrane space of the organelle. This proton motive force is harnessed in the electron transport chain by ATP synthase to generate ATPs.

When an E. coli cell is infected by multiple phages, what route of infection (lytic or lysogenic) will the phages take? Why?
Artyom0805 [142]

Answer:

When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.

Explanation:

When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.

The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators O_{L} and O_{R}  each contains 3 repressor binding sites (O_{L_1} ,    O_{L_2},O_{L_3} and O_{R_1},O_{R_2},O_{R_3})  that are differently occupied under different conditions.

The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.

The lytic development occurs in cells infected with lambda phage that carry  C_1 gene.

In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.

To ensure that a human gene is translated properly in a bacterial cell, you should clone the _____________ for the gene instead
bekas [8.4K]

Answer:

complementary DNA (cDNA)

Explanation:

The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.

Mike earned scores of 88,91,75,and 72 on four math tests determine his score on the fifth test if his average for five tests was
My name is Ann [436]

Explanation : x = 79 marks

The marks scored by Mike on four math test are 88,91,75 and 72.

Average of marks, A = 81

Let in fifth test he scores x marks.

The formula for finding average is :

A=\dfrac{sum\ of\ scored\ marks}{no.\ of \ tests}

81=\dfrac{88+91+75+72+x}{5}

\dfrac{326+x}{5}=81

x=79

In the fifth test he scores 79 marks.

Hence, this is the required solution.
