Answer:
<h2>In prokaryotes both transcription and translation occurs in cytoplasm (they lack true nucleus) while in eukaryotes, transcription occurs in nucleus while translation occurs in cytoplasm.</h2>
Explanation:
1. Prokaryotes do not have nucleus, so both transcription and translation occurs in the cytoplasm, therefor translation start before the completion of transcription.
2. While in eukaryotes, they have true nucleus, and there protein synthesis machinery (ribosomes) and is situated in the cytoplasm.
So in eukaryotes transcription occurs in the nucleus, and after the completion of transcription, mRNA is processed and finally export into cytoplasm for translation.
I believe Venus! because you can usually see it at sunset and at sun rise
Answer:
The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
False.
Any time a scientific theory is challenged, it means it's not a good
theory. And this statement is not valid. In theoretical models, they are
revisited when there are further studies and discoveries found in a certain
area where they can be remodeled and reintegrated instead of disregarding its
credibility. Models, theories and paradigms are not challenged but rather
encouraged, they are supported in many studies since these theories and models
were created in order for us to understand a certain phenomenon but it would
likely help the scientific society to be updated in the new forms or spheres of
improvement rather than discouragement.
