Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Explanation:
there's a better explanation, but I don't know what your question is
Answer:
a. are often transmitted by fecal contaminated water and food.
Explanation:
<em>Eschericia coli</em> belongs to a group of bacteria generally referred to as fecal coliforms because they are of fecal origin.
<em>Hence, their common mode of transmission is through fecal to oral routes such as fecal contaminated food, water and any other substance that passes through the mouth.</em>
<em>E. coli </em>infections can be treated using suitable antibiotics.
The correct option is a.
Answer:
For the first question I think it's C - The mRNA was not bound by a ribosome. I'm not 100% sure sorry if I'm wrong. I tried my best to figure it out.
Explanation:
For question two I think it's C- Replication replacing an amino group. I'm not 100% sure sorry if I'm wrong. I tired my best to figure it out.
Answer: b. removal of introns from mRNA
The process by which Ribosomes attached to ER or lying freely in the Cytoplasm synthesize proteins from the transcribed mRNA of the DNA is called Translation.
Explanation:
It is made up of three stages;
1. INITIATION;Options C mRNA binding to the ribosome
2. ELONGATION ;Option D joining large and small ribosomal subunits
3, TERMINATION;Option E chain termination at a stop codon
However, Introns are non coding region of RNA base sequence transcribed from the DNA, or sections of DNA encoding the RNA. It is an unwanted part which must be sliced out before translation. Therefore it is not a relevant steps of translation, and hence Option B is the wrong answer.
Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.
