The answer is B :),this sentence has to be longer LOL
Answer:
49
It says that there are eight four-base repeat unites that make up the remaining 32 bases. This means that it 8 x 4 = 32. Then from 32 + 9 = 41 is how you get all of the bases in the original. However, if there were to be 10 repeat units then it would be <u><em>10</em></u> x 4 = 40. Then from there you would get 40 + 9 = 49. Hope my explanation helped somewhat.
Answer:
The process of making a copy of gene is called DNA replication.
Explanation:
This is a four step process. In first step, the DNA molecule which is double helical structure is unzip. This is carried out by enzyme called helicase which is also called biological scissors. Then after that DNA form Y like structure having complementary base pairs. Two strands are formed ; leading strand and lagging strands. They complementary base pairs allow the formation of new strands with help of primer. So new strand is then a copy of gene or called replicated strand.
Answer:
pollution is the introduction of harmfull material in the invironment called pollution
Answer:
1. Leads to mixing of genetic materials hence variation within species
2. Leads to offspring with hybrid viguor that tend to show high and adaptability to environmental conditions.
3. Variations due to sexual reproduction leads to improvement of species hence evolutionary changes that may bring about specialisation
