According to the central dogma, which of the following represents the flow of genetic information in cells?
const2013 [10]

Answer:

DNA to RNA to protein.

Explanation:

Central dogma in biology was given by Crick in 1957. The central dogma explains the flow of genetic information in the cells.

According to the central dogma, DNA can multiply and increase its number by the process of replication. The information from DNA is changes to RNA by the process of transcription. The expression of protein product expression occur from the RNA by the process of translation. Hence, the information travels from DNA to RNA to protein.

Thus, the correct answer is option (2).

A species that humans bring to an area where it did not previously occur is a(an):_________
Tasya [4]

A species that humans bring to an area where it did not previously occur is a(an): exotic species.

Exotic species are those that exist outside of their native geographic range, also known as alien, nonnative, nonindigenous, or introduced species. Exotic species are those that people have purposefully or accidentally introduced into ecosystems outside of the ones in which they have evolved. These introductions undoubtedly happen regularly in nature.

For instance, the Japanese native Kudzu (Pueraria lobata) was brought to the United States in 1876. Due to either a lack of imported individuals or inadequate adaptation to the ecosystem they join, the majority of attempts to introduce exotic species are likely to be unsuccessful. However, some species have preadaptations that can help them thrive even more in a novel setting.

If you took dna samples from two strangers on a street,how similar would their dna be?
Verdich [7]

The correct answer is: about 99%.

The main difference between two random people’s genetic make-up issingle base pair differences, or polymorphisms (SNPs). There are about one SNP per 1000 bases. Since the human genome is about 3 Gbp long, about 3 million SNPs among two random people is present. SNPs may occur within coding sequences of genes, non-coding regions of genes, or in the intergenic regions.
