Answer:
Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes.
Explanation:
Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
Answer:
The body needs protein to build and repair tissues to make hormones, enzymes, body chemicals e.t.c.
The body also uses protein as a building block of blood , bones, skin , muscles, cartilage e.t.c.
Explanation:
Nothing
Explanation:
Mass of the sample = 500g
Decay rate per anum = 11%
Unknown:
Mass of sample remaining after 10yrs = ?
Solution:
This is a simple percentages problem;
The radioactive sample loses 
x 500g of sample per year;
this is a loss of 55g per year;
In 10years time, the sample would have lost 10 x 55g = 550g of element.
Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
