Before answering the question, you should know that exons/intron systemin the gene exists only in eukaryotes. A gene can have many exons with introns between them, but in RNA maturation, these exons will be joined together to form one RNA to code for one protein (There's no relation between exons number and how many proteins are formed).
In prokaryotes it is different there's no exons/introns, but their gene can be transcripted to a polycistronic RNA which can give after translation more than one proteins.
Answer: Option C
Explanation:
Protein building begins on the DNA strand. Usually, the DNA contains genetic information which flows from nucleic acids to proteins in a series of steps:
1) Replication: this is the first step. It involves the copying of parental DNA into daughter copies.
2) Transcription: this is the second step. Here, parts of the coded genetic message in DNA are copied precisely in the form of RNA - in the form of messenger RNA (mRNA).
3) Translation: this is the third step. Here, genetic message coded in mRNA is translated, on the ribosomes, into a protein with a specific sequence of amino acids.
Simply put, DNA makes RNA, and RNA makes protein.
Answer:
Paramecium- 0 days/ 50 paramecium
5 days/400 paramecium
10 days/ 900 paramecium
15 days/ 860 paramecium
Bear- 0 days/ 2 bears
20 years/ 26 bears
40 years/ 230 bears
60 years/ 250 bears
80 years/ 248 bears
100 years/ 252 bears
Explanation:
The population of the paramecium will keep on increasing until an equilibrium is reached. The resources will become limited and hence, the paramecium will start competition for the limited resources. As a result, the population of the paramecium will decline rapidly after equilibrium.
The growth rate of bear is very less as compared to that of paramecium growth rate. Along with the growth rate, there are other factors which will be responsible for its numbers such as resources, hunters etc. Also, it uses sexual method of reproduction hence the growth rate will not be like the paramecium growth rate.
Answer:
6 carbon dioxide molecules
The answer is D. Because planting nonnative species is bad for the area because the plants that normally grow there have to compete with that new species then.
