Answer:
O H20 and CH4, but not O2
Explanation:
Compounds consist of multiple elements. O2 is just two oxygen atoms, meaning two atoms from the same element.
Answer:
The correct option is : cells containing empty plasmid vectors
Explanation:
The blue-white screen is a technique which involves the rapid identification of the recombinant bacteria in a vector-based molecular cloning experiment. In this method, a DNA ligated vector is inserted in a host cell which is viable for transformation and grown in presence of X-gal.
The cells that are transformed with the vectors having the recombinant DNA produce the white colonies. Whereas, the cells transformed with empty vector i.e. the non-recombinant plasmids, produce the blue colonies.
The answer is <span>a frameshift deletion at the beginning of the gene.
The frameshift deletion means that due to the deletion, the reading frame will be changed. Because of this, changed mRNA will be synthesized and translated into altered protein. It is known that codon is a triplet (a set of three nucleotides), that code for certain amino acid. The earlier in the sequence the deletion occurs, the protein will be more severely affected.
For example, if codons on RNA are THE BIG BAD DOG and the frameshift deletion happens on the first triplet (earlier in the sequence), the changed sequence will be TEB IGB ADD OG. If </span>the frameshift deletion happens on the third triplet (later in the sequence), <span>the changed sequence will be THE BIG ADD OG.</span> This way, if the<span> frameshift deletion occurs at the beginning of the gene,</span> the more codons will be changed and in turn, they will code different amino acids.
I believe the polysaccharide that provides rigidity and strength in plants would be cellulose. As this is one of the essential components found in the cell wall of plant cells.
