Based on the observance of DNA, now appearing as 3 segments, the purpose of the enzyme was most likely to split and or break down, cut the DNA at appropriate sites of the respective nucleotide sequences, that the enzyme can recognize and cut, ultimately producing these 3 segments.

3. Describe the difference between sexual and asexual reproduction. Give at least one example organism for each type.
Salsk061 [2.6K]

Answer:

Since sexual reproduction requires two individuals, it allows intermingling of genes which is beneficial for the individuals as well as the entire species. The organisms produced by asexual reproduction are genetically identical to each other. ( I hope it helps )

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymer
BigorU [14]

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

Answer:

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

Ions are transported across membranes using __________, which requires __________.
VashaNatasha [74]
To complete the statement above:

Ions are transported across membranes using channel-mediated facilitated diffusion; which requires <span>kinetic energy.


The channels can be opened by the requirements of the cell. Transmembrane proteins, called transporters, utilize the vitality of ATP to drive particles or little atoms through the layer against their focus angle.
