yarga [219]

Answer:

I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>

Explanation:

I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.

I found rods, and some are gram positive and long. They others are gram negative and very small and short.

The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>

The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.

#8 - The Genetic Code<br> 18. How many amino acids are involved in the production of proteins?
Phoenix [80]

Answer: 20 amino acids

Explanation:

The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.

Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
