a single stranded dna (oligonucleotides) can hybridize with (select one): select one: a. complementary dna b. complementary rna

garri49 [273]

A single stranded DNA (oligonucleotides) can hybridize with (d) both complementary DNA and complementary RNA.

DNA is the Deoxyribonucleic Acid. It is the genetic material present in majority of organisms. The nitrogenous bases present in DNA are: Adenine, thymine, Guanine and Cytosine. DNA is a double stranded structure hence it forms hydrogen bonds with a complementary strand. The complementary strand can be of a DNA or RNA.

RNA is the Ribonucleic Acid. It also is a genetic material present in very few organisms. RNA is less stable than the DNA and may be either single stranded or double stranded. The nitrogenous bases of RNA are: Adenine Uracil, Guanine and Cytosine.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s

inn [45]

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

$h^{2}=\frac{R}{S}$

$h^{2}=\frac{0.14}{0.77}$

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.

What is DNA, and how does it function in cells?

Tom [10]

DNA, short for deoxyribonucleic acid, is present in the nucleus of eukaryotic cells and floats around in the cytoplasm of prokaryotic cells. DNA produces blueprints which RNA carry out to ribosomes to code for protein. You can say that DNA passes genetic material through generations.
