Ribosomes translate DNA. False True

Biology
2 answers:
Fed [463]3 years ago

Answer:

True

Explanation:

DNA is transcribed to make an mRNA in the cytosol. Ribosomes can start translating the mRNA before it is even completely transcribed. No post-transcription processing steps are necessary. The mRNA contains three coding sequences from three different genes, each specifying its own polypeptide.

Nikolay [14]

Answer:

30 minutes

Explanation:

Bacteria reproduce by binary fission, a process by which one parent cell divides to form 2 progeny cells. Because one cell produces 2 progeny cells, bacteria are said to undergo exponential ( logarithmic) growth.

As in the case of staphylococcus aureus, we start with 100 cells ,  and after 90 minutes number becomes 800 that means  , firstly the cells doubled (100 x 2 = 200 ) after 30 minutes. Again after 30 minutes they doubled ( 200 x 2 =400 ) and again after 30 minutes they doubled (400 x 2 = 800). So in 90 minutes 100 cells became 800 cells.

Hence the generation time for S.aureus is 30 minutes.

ICE Princess25 [194]

Answer:

Reduce genetic diversity

Explanation:

Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.

In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.

This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
