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.

What did Charles Darwin discover as a result of his experiments with breeding pigeons?
Sphinxa [80]
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.

What should police officers do to prevent false identifications during lineups?
jeka94
To prevent false identifications during lineups, the police officers should tell the witnesses that the lineup may not include the suspect. The eyewitness identifications are subject to a high rate of error because witnesses are subject to high stress or anxiety, the human memory tends to reconstruct incidents because humans do not have the capability to record memories like a video recorder; witnesses often focus on weapons, and not the identification of the perpetrator, among other reason.

Which characteristic do most adult fungi and plants share? A- they're both producers  B- both have cells with cell walls   C- Bo
zimovet [89]
It is not A because: fungi are decomposers rather than producers.
It is B--both do have cells with cell walls.
Not C because: plants reproduce through pollination of flowers.
Not D because: neither have multiple nuclei in a single cell.
