If a cell contains a set of duplicated chromosomes, does it contain any more genetic information than the cell before the chromo
zmey [24]

Answer:

No.

Explanation:

When the set of chromosomes are duplicated, it means the chromosomes will be double the number.

However the genetic information will not change. It will remain the same.

Duplication of chromosomes is usually occurs among the interphase stage of mitosis where chromosomes will duplicate to ensure the formation of two identical daughter cells.

In these cells there will be no addition or variation in genetic information.

What structures solve the end replication problem for linear chromosomes?
omeli [17]

Answer:

Eukaryotes have solved the end-replication problem by locating highly repeated DNA sequence at the end, or telomeres, of each linear chromosome.

Explanation:

Telomeres are stretches of DNA at the ends of the chromosome, They protect the genetic data and make it possible for cells to divide.

Answer:

1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.

2. Fossil evidence: organisms changing form over time through the fossil record.

Direct observation. We can directly observe small-scale evolution in organisms

with short lifecycles (e.g., pesticide-resistant insects).

The benefit of measuring the initial rate of a reaction, V0, is that early in the course of the reaction, A) Km is the substrate
aleksandr82 [10.1K]

Answer:

Rate of product formation is linear and [S] has not been lowered significantly.

Explanation:

The rate of enzyme-catalyzed reactions is affected by several factors, the contraction of substrates [S] is one of them. The substrate concentration keeps on changing as the reaction proceeds. This is why the reaction rate is measured at the initial stages of reactions when the substrate concentration [S] is much greater than the concentration of the enzyme. It is called the initial rate or initial velocity.

Under the conditions of higher substrate concentration and relatively much lower enzyme concentrations, only a few molecules of substrates are being converted into product. At a relatively higher substrate concentration, the rate of product formation increases linearly.
