<span>Farmer Brown might be hesitant to clone his corn because cloning eliminates the ability to sexually reproduce and provide genetic variability. There will be no variability in genes in these clones, because given that they are exact copies of their "parent," they will all be identical, without any difference or variation. This farmer doesn't want that to happen, which is why he is hesitant to take Farmer Green's advice.</span>
I believe temperature is the answer
Answer:
The correct answer will be option-E.
Explanation:
The CRISPR-Cas9 system is a simple and most versatile genome-editing tool to edit the genome of an organism.
The system consists of two components: "Cas-9 enzyme" which act like molecular scissors to cut the DNA and "Guide RNA or gRNA" which guides the Cas-9 enzyme to the target DNA by binding to the target DNA.
The gRNA consists of 20 bases long RNA sequence which is complementary to the sequence of the target DNA. This binding ensures the right binding and cutting of the target DNA.
Thus, option-E is the correct answer.
DNA replication proceeds in one direction around the bacterial chromosome.
Explanation:
Replication of DNA is preserved across most of life. Therefore, even bacteria DNA replication occurs bidirectionally. During replication of DNA, A primer is required in the initiation complex before DNA polymersae can begin replication. This is because this enzyme works by adding DNA nucleotides at the 3’ end of an existing strand. DNA can have several replication forks on one double strand in which replication occurs. For every fork, there is a leading strand whereby the replication process by DNA polymerase is continuous and the lagging strand whereby the replication is done in bits by the same polymerase enzymes. The lagging strand will, therefore, require many primers. This is becaue strands of DNA are antiparallel yet the DNA polymerase has to move in one direction. Since replication can only occur in the 5’⇒3’ direction, the antiparallel strand will be done in 5’⇒3’ chunks that will later be joined into one strand.
