A student used poster board to construct this model of DNA.Which statement describes this model of DNA?
pantera1 [17]

Answer:

The model is inaccurate because the base pairs are incorrect.

Explanation:

The model of DNA that the student made was:

G-G

A-A

T-T

C-C

G-G

A-A

T-T

C-C

The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.

The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

As the electrons pass through the electron transport chain between Photosystem I and II, they use their energy to pump _________
skelet666 [1.2K]

Answer:

protons /H+

thylakoid membrane of the chloroplast

acid.

Explanation:

This is chemiosmosis. And the ultimate aim is to synthesis ATPs. Proton Motive Force generated from the electron transport chain continuously pump protons(H+) from the stroma into the thylakoid membrane of the chloroplast,

The build up of  protons/H+ generated electrochemical gradients between this  space and the stroma.

Therefore proton/H+ diffused down the gradient into the stroma. The energy generated from the downwards diffusion is used by the ATPase synthase to synthesize ATPs from ADP and inorganic phosphate (Pi), to be used in Calvin Cycle for CHO, productions.

The protons/H+ pumped by PMF and  concentrated in the thylakoid memebrane is obtained from the  split of Hydrogen atoms  to electrons(e-) and H+. since pH is negative Log of [H+], therefore the space will be acidic from large concentration of H+/protons.

ziro4ka [17]

Answer:

Complete question:

We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the six modes of inheritance are consistent with this pedigree: Select one or more Y Linked Autosomal Recessive Autosomal Dominant X-Linked Dominant X-Linked Recessive We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder, Assuming the pedigree is accurate, indicate which of the six modes of inheritance ere consistent with this pedigree Select one or more X-Linked Recessive Y Linked Autosomal Recessive X-Linked Dominant Autosomal Dominant.

Answer:

After the analysis of this pedigree, it is clears that the inheritance pattern is X linked because the offsprings are affected with parents genotgype

Explanation:

The inheritance is X linked dominant because of the presence of one dominant gene for the affected genotype in male.

The male individuals are affected. This is therefore not a recessive inheritance in later case, it is only when the two genes are present at the same time the affected genotype will be seen.
