<span>One of the factors that threatens biodiversity is deforestation. Deforestation threatens biodiversity because it is destroying the habitats of many animals and without their habitats, the animals die. One way biodiversity can be preserved is to limit deforestation. On a small scale, an individual can help to do this by reusing their paper bags so that is a less demand for paper and as a result, trees to be cut down.</span>

A certain bacterial mRNA is known to represent only one gene and to contain about
Brut [27]

Answer:

C) 30,000

Explanation:

According to the given information, the bacterial mRNA consists of about 800 nucleotides. Three consecutive nucleotides together make one genetic codon which in turn codes for one specific amino acid in the protein encoded by this mRNA.  

So, an mRNA with 800 nucleotides will have total 800/3 = 266.67 or 266 genetic codes. The protein encoded by this mRNA would have a total of 266 amino acids.  

Given that one amino acid imparts 110 units to the molecular weight of the protein, the protein with 266 amino acids have the molecular weight= 266 x 110 = 29260, that is about 30,000.

swat32

Answer:

Pleiotropy

Explanation:

Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism

  • <em>gene pleiotropy</em>
  • <em>developmental pleiotropy</em>
  • <em>selectional pleiotropy</em>
  • <em>antagonistic pleiotropy </em>

<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
