The toxic cyanide anion (CN-) binds to cytochrome c oxidase and prevents electron transfer. Dosing of BP-CML cells with cyanide
astra-53 [7]

Answer: C. Ii & III are correct

II. reduced intracellular ATP.

III. apoptosis or necrosis.

Explanation:

Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.

Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.

The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.

Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.

HELP ASAP<br> Punnett Squares
pashok25 [27]

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.

Which of the chains of amino acids corresponds to the nucleotide sequence AAUGGCUAC?
masha68 [24]
The correct answer is d - asparagine - glycine - tyrosine. The genetic code found in DNA is responsible for defining amino acids. It is the triplet of bases in DNA and RNA that define and direct which amino acid is used in the synthesis of a particular protein. The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Of these, three triplets or codons do not code for any amino acid and are thus called non sense codons. The remaining 61 codons are called sense codons.
