Where is the Electron Transport System (ETS) located in prokaryotic cells?
kenny6666 [7]

Answer:

Cellular membrane.

Explanation:

In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.

The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.

Why must each chromosome make a copy of itself before the m phase begins
klio [65]

The each chromosome makes the copy of itself before the M Phase in mitosis because the resultant daughter cell the chromosomes is genetically identical.

<u>Explanation:</u>

The parent cell in the chromosomes make the copy before mitosis. The copy is occurred during the S phase of inter phase. During the mitotic M phase, the cell divides the copied DNA and cytoplasm to make two new cells.

M phase involves two distinct related processes which is mitosis and cytokineses ;the cell growth steps into the new stage and cellular energy is developed on the division in the phase .

which statement is false about base stacking when nucleic acids are in a double-stranded conformation?
Lilit [14]

The statement that is false about base stacking is; B. Stacking interactions are hydrophilic in nature.

<h3>What is the truth about Base Stacking?</h3>

Base stacking is defined as a common arrangement of nucleobases that are found in the three dimensional structure of nucleic acids. Bases (or base pairs) are planar, and these planes stack at contact distance , excluding water and maximizing Van der Waals interactions.

Looking at the given options, the only one that can be said to be false about the defined base stacking above as regards nucleic acids is option B.

The missing options are;

A. Stacking interactions occur when two or more bases are positioned with their rings parallel to each other.

B. Stacking interactions are hydrophilic in nature.

C. Stacking involves a combination of van der Waals and dipole-dipole interactions between bases.

D. Base stacking helps to minimize contact of the bases with water.

E. Base stacking interactions are important in stabilizing the three-dimensional structure of nucleic acids.

Color-Blindness is a genetic condition that follows the pattern represented in the chart. Based on this information, you can det
blagie [28]

Based on the information, you can determine that color-blindness is X LINK RECESSIVE.

C) X-linked recessive.

<u>Explanation:</u>

Color blindness is the common hereditary condition that is hereditary passed from their parents. The gene for the color blindness found in the chromosomes. So for the male to be color blind. X linked color blindness is the recessive traits.

Female heterozygous of the trait have a normal vision. The X link recessive is the mode of the inheritance in which the mutation of the gene on the chromosomes causes the depletion in the phenotype because the male has one Y and one x chromosomes.
