Rna polymerase moves in which direction along the dna? 35) ______
yulyashka [42]

The answer is C. This is because nucleotide elongation involves the addition of a nucleotide to the 3 prime carbon of the previous nucleotide carbon ring. This involves a dehydration reaction between the phosphate group on the 5 prime carbon of the last nucleotide to the hydroxyl group of the 3 prime carbon of the previous nucleotide.

How does reproductive isolation result in speciation
sergij07 [2.7K]

Speciation is the adaptive divergence and gradual that leads to two different species.

Reproductive isolation results in speciation when the processes of evolutionary mechanisms, physiological and behaviours are collected.

Mechanism of reproductive isolation helps in preventing members of different species from producing offsprings. A zoologist is a classified way of reproductive isolation whereby it(zoologist) is classified to the mechanism of reproductive isolation into two categories

(i)                  Pre-zygotic. This one acts before fertilization or before mating when it comes to animals.

(ii)                Post-zygotic. It acts after fertilization.

The mechanisms appear I species which are genetically controlled and whose geographic distribution overlaps or are separated.

Cilia are found in certain:__.
d1i1m1o1n [39]

Cilia are found in certain a. protozoa.

In the field of biology, cilia can be described as thread-like projections which are membrane-bound, found in mammals and various microorganisms referred to as ciliates.

Protozoa are eukaryotic organisms that are single-celled. The protozoa can either live freely or choose a parasite to live in.

Cilia are present in certain protozoa in order to help the protozoa in movement. The cilia also help the protozoa in gathering food for nutrition. The cilia also make it possible for protozoa to attach to a surface. Sensations in a protozoa can also be generated through cilia.

The cilia cover the entire surface of the protozoa cell.

This interprets an RNA message into a string of amino acids called a polypeptide. Either single polypeptide or many polypeptides
vovangra [49]

Answer:

The correct answer is - translation

Explanation:

The translation is the second process involved in the protein synthesis in which mRNA that was encoded the genetic information from the DNA code during the transcription process, produces the amino acid sequence with the help of ribosome and tRNA.

These RNA messages or codes are decoded by the ribosome that produces a specific sequence of codes that form specific amino acid decided by the triplet code they produces. These amino acids together form polypeptides chain and single polypeptide or many polypeptides working together make up a protein.
