The leading strand is the strand of nascent DNA which is being synthesized in the same direction as the growing replication fork. A polymerase "reads" the leading strand template and adds complementary nucleotides to the nascent leading strand on a continuous basis.

In an experiment, a certain colony of bacteria initially has a population of 50,000. A reading is taken every 2 hours, and at th

Iteru [2.4K]

Answer:

1) Recursive definition: $p_n = (50,000)3^n$

2) At the beginning of the 4th interval

Explanation:

The initial population of the bacteria at time zero is

$p_0 = 50,000$

Here we are told that the reading is taken every two hours; we call this time interval "n", so

$n=2 h$

And also, after every time interval n, the number of bacteria has tripled.

This means that when n = 1,

$p_1 = 3 p_0$

And when n=2,

$p_2 = 3 p_1 = 3(3p_0)=9 p_0$

Applied recursively, we get

$p_n = 3^n p_0$

And substituting p0,

$p_n = (50,000)3^n$ (1)

Here we want to find at the beginning of which interval there are

$p=1,350,000$

bacteria.

This means that we can rewrite eq.(1) as

$1,350,000=(50,000)3^n$

By simplifying,

$27=3^n$

Which means that

$n=3$

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.

These bacteria change the nitrogen in the atmosphere into a form that we can use to make proteins

Dmitry_Shevchenko [17]

Answer:

Cyanobacteria, Anabaena and Azotobactor are called Nitrogen fixing bacteria. These bacteria change the nitrogen in the atmosphere into a form that is used by the plants to make proteins. Plants take nitrogen in the form of nitrates. The atmospheric nitrogen is first converted into ammonia after that ammonia is converted into nitrates and this nitrates use by the plants to make proteins.
