Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
Answer:
Explanation:
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products.
Answer:Answer: Since certain bases always appear in pairs, they will have equal percentages of the DNA composition. The percentage of adenine will equal the percentage of thymine, and the percentage of cytosine will equal the percentage of guanine. Together, these percentages will add to 100%
Explanation:
Answer:
The options
a.social moral reasoning.
b.conventional moral reasoning.
c.postconventional moral reasoning.
d.preconventional moral reasoning.
The CORRECT ANSWER IS b.
b.conventional moral reasoning.
Explanation:
The conventional level of moral reasoning is particular of adolescents and adults. To think in a conventional way is to presume the morality of actions by contrasting them to society's opinions and standard.
In this case, the morality of an action relies majorly on peer acceptance.
Take for instance: I would turn down the act of drinking and driving due to what my friends will reason of me and my perception of belittling myself.
Conventional moral reasoning judges an action by its compliance to society's rules so as to promote social order just as in this case study.
