The first step in sequencing of DNA into a protein is called transcription. Transcription refers to transcribing a strand of DNA to a single strand of messenger rNA or mRNA. The mRNA is then modified (removal of introns, splicing of exons, adding the 5' cap and the poly-A tail, etc) then transported to the nucleus. The second step is called translation. Translation is refers to translating the mRNA strand into its corresponding amino acid based on codon sequences.
Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm. Bacteria can do this through several mechanisms.
Answer:
The correct answer is - Similar nucleotides are present in both fruit-fly and frog DNA.
Explanation:
Fruit fly or drosophila DNA sequence and DNA sequence of the gene of frog for a particular trait is combined and heated to separate the DNA strands by separating the nucleotides present between the strands of both organisms.
This is observed after cooling down the single strands after paired up that some of the DNA paired with the DNA. This is only possible if the DNA strands of the particular gene have similar nucleotides to form hydrogen bond in single strands of DNA of frog and fruit-fly.
1) What sequence of nucleotides does the guide RNA need to include, to kill the bacterium is the answer.
2). The action of the Cas-9 protein.
Explanation:
CRISPR is a genetic engineering technology used to detect and destroy DNA of the bacteriophage which have infected the bacterial cell previously.
The CRISPR are the sequences of bacteriophage DNA found in genome of the bacteria when bacteriophage has infected it before.
It alters the DNA sequences and modify the function of gene is bacteria.
Cas-9 is an endonuclease which cuts the DNA identified by or complementary to CRISPR.
This system makes bacteria anti viral.
It is an example of acquired immunity.
This process involves replication<span> of the </span>cell's<span> chromosomes, segregation of the copied DNA, and splitting of the parent </span>cell's<span> cytoplasm. The outcome of binary fission is two new </span>cells<span> that are identical to the original </span>cell<span>. In contrast to prokaryotic </span>cells<span>, eukaryotic </span>cells<span> may divide via either </span>mitosis<span> or meiosis.</span>
