In an important experiment, a radioactively labeled bacteriophage was allowed to infect bacteria. In a first trial, the phage co

ntained radioactive DNA, and radioactivity was detected inside the bacteria. Next, phage containing radioactive protein was used, and the radioactivity was not detected inside the bacteria. These experiments led to the conclusion that:_____.
A) DNA is made of nucleotides.
B) genes carry information for making proteins.
C) the genes of this phage were made of DNA.
D) bacteriophages can infect bacteria.

Answer: C) the genes of this phage were made of DNA.

Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.

<span>Agar is known to be a gelatinous polymer substance that was commonly used in the laboratory setting as a substrate. Thus, nutrients agar can grow different types of microbes such as fungi and bacteria while MacConkey agar is made with bile salts and crystal violets, these additives cause the agar to only grow Gram – negative bacteria. However, nutrients agars grow more organisms because it contains nutrients from either beef broth or yeast extracts when compared with MacConkey agar.</span>

If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be ind
ludmilkaskok [199]

Answer:

Option B, Co-dominance

Explanation:

This is an example of codominance inheritance pattern.

When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .

For example -

A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"

Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.

The same thing is happening in case of true breeding black and white mice.

Hence, option B is correct

What is the main purpose of mitosis? A. to help the cell grow larger B. to divide the cytoplasm C. to separate sister chromatids
denis23 [38]
I think its C. This is because your making two cromatited pairs when doing the process and then pulled apart to make two daughter cells. apart It's not D because that's what raication is. Its not A because your dividing the cell in to two more cells. It's not B because you can't really divide the cytoplasm.
