Answer:

The correct answer is - option B. sister chromatids.

Explanation:

When a one strand DNA of a chromosome replicates itself into two identical copies of DNA formed, these two identical DNA copies are called as sister chromatids.

Dyad is a pair of sister chromosomes and each sister chromosome have two chromatids. The formation of the sister chromatids takes place in the S phase of interphase which is also called the synthesis phase.

Thus, the correct answer is - option B. sister chromatids.

Consider the atps that can be generated via substrate-level phosphorylation. Will glycolysis be useful for generating any atps d
iris [78.8K]

Indeed, glycolysis would be useful for creating ATP as it produces a net increase of ATPs. One glucose particle produces two ATP in a cycle. On the off chance that the ETPUM experiences the procedure of aging, at that point the natural atoms would then be able to be used as the essential electron transporter. Two ATPs would be delivered by means of TCA cycle and yes it will be sufficient to help development.  

Further Explanation:  

Phosphorylation:  

Phosphorylation is the synthetic expansion of a phosphoryl gathering (PO3-) to a natural atom. The expulsion of a phosphoryl gathering is called dephosphorylation. Both phosphorylation and dephosphorylation are done by catalysts (e.g., kinases, phosphotransferases).  

ATP:  

Adenosine triphosphate is an unpredictable natural synthetic that gives vitality to drive numerous procedures in living cells, for example muscle withdrawal, nerve motivation proliferation, and substance amalgamation. Found in all types of life, ATP is regularly alluded to as the "atomic unit of money" of intracellular vitality move.  

ATP utilized for:  

ATP Molecule. The Adenosine triphosphate (ATP) particle is the nucleotide referred to in organic chemistry as the "atomic cash" of intracellular vitality move; that is,ATP can store and move substance vitality inside cells.  

TCA:  

Tricyclic antidepressants (TCAs) are a class of drugs that are utilized basically as antidepressants. TCAs were found in the mid 1950s and were promoted later in the decade. They are named after their concoction structure, which contains three rings of particles.
