Answer:
Some mutagens strip DNA nucleotides (bases) of essential modifications—for example, they deaminate the bases—such that these bases resemble different nucleotides and confuse the DNA replication machinery. Subsequent rounds of DNA replication then permanently incorporate such changes.

The statement that is true is active transport moves against the concentration gradient.
<h3>WHAT IS ACTIVE TRANSPORT</h3>
Active transport is one of the two types of cellular transport that involves the movement of molecules against a concentration gradient.
This moves that movement occurs from a region of lower concentration to a region of higher concentration. Since movement is against a concentration gradient, it involves input of energy (ATP).
Therefore, the statement that is true is active transport moves against the concentration gradient.

Answer: IV: the tire treads. DV: The braking distance of the car
Explanation:
Answer:
Option D is correct.
Explanation:
Option a) given in the option that if promoter is altered it will inhibit transcription which is the process by which information present in DNA converted to mRNA which require RNA polymerase which bind to promoter site so if promoter is altered RNA polymerase will not bind so transcription will be inhibited but above question is asking about inhibition of translation due to binding of miRNA-delta molecule to Q mRNA so this option can be eliminated.
Option b if miRNA binding site sequence is altered miRNA molecule will not be able to bind to Q mRNA so translation will not be inhibited hence option b is incorrect
Option c translation of Q mRNA is inhibited when miRNA - delta is present not absent
So option c can be eliminated
Option d if miRNA binding sequence is altered miRNA molecule if present will not bind to Q mRNA hence translation of Q mRNA will occur & not inhibited
Hence option d is correct
