Which alleged father has a DNA fragment that matches the size of one of the child's DNA fragments and is, therefore, likely the
Serga [27]

Answer:

Alleged father #2

Explanation:

Normally alleged father #2 has in common with the child the gene that every man would, this would not be evidence that he is the father. But, in the case of finding a really strange trait with the kid that would not be coincidence, in that case it would be a high probability of paternity.  This genes need to be analyzed in the nucleus of the cells where the units of heritage are present making us unique individuals according to the infinite combinations that ca be present in our DNA.

How could an error during transcription affect the protein that is produced?
Ahat [919]

Answer: An error during transcription could produce a shorter protein or induce changes in the protein's sequence.

Explanation: Transcription is the process of single-stranded RNA synthesis from a DNA template (gene). During this process, RNA polymerase reads the DNA template and synthetize RNA, keeping the sequence. The RNA sequence will be reading later by ribosomes and protein will be produced. An error in transcription could produce changes in codons that are sequences of 3 nucleotides that determine  aminoacids of the protein, and that would change protein folding and inactive it. Another possible result would be that  error in transcription produce a premature stop codon that cause a shorter inactive protein.

Which statements about the production of ATP ATP in chloroplasts are true? The production of ATP ATP in chloroplasts does not re
Lostsunrise [7]

Answer:

A proton gradient is generated by the transport of protons into the thylakoid lumen.

Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.

Explanation:

During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).
