What items are used to identify the genetic makeup of an unknown organism?
OleMash [197]

Answer:

Polymerase chain reaction machine

Primers

Petri dishes

Test tubes

Pipettes

DNA Polymerase

Free nucleotides

The organism to be identified

Explanation:

To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.

To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.

How many different proteins, each composed of 8 amino acids, can be constructed using the 20 different amino acids found in prot
Darina [25.2K]
To solve this, you would need to identify the number of amino acids (20) you are dealing with and the number of positions (8) that are available in your polypeptide. so that would come out to 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 = 20^8

I need help with the image (phenotypes and genotypes).
Flauer [41]

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>
