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.
The answer is C.
Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.
Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.
DNA polymerase moves along the old strand in the 3'-5' direction, creating a new strand having the same 5'-3' direction.
The answer is Transcription.
Transcription is the first step to gene expression. This
process happens when a certain part of the DNA is being copied into RNA. This
process allows the DNA to at least transfer at least one gene to the RNA
Answer:
Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
