Answer: Option A) How many codons make up a typical mRNA molecule?

Explanation:

A messenger RNA (mRNA) molecule is a class of RNA molecules, each of which is complimentary to one strand of DNA. It carries the genetic information of genes from the chromosomes to the ribosomes where the information is translated into the amino acid sequence of a polypeptide.

Thus, the codons on a typical mRNA molecule differs from the DNA template strand by the presence of URACIL (U) instead of thymine (T).

Use the graph below to answer the following question: What is happening to the object's velocity?
trasher [3.6K]

Answer:

The object's velocity is increasing

Explanation:

From the graph above, we can deduce that the velocity is increasing. From the first stage, v=m/s=0.

At the third stage, v=20/2= 10m/s.

At the 5th stage, v=80/4=20m/s.

This shows velocity is increasing.

A situation in which the coefficient of coincidence is greater than 1.0 would indicate that: A. no double crossovers were found
damaskus [11]

Answer:

B. there were more double crossovers in the progeny than would be expected based on probability

Explanation:

Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:  

Coefficient of coincidence  (COC) = ADRF / EDRF

where ADRF = Actual Double Recombinant Frequency

and  EDRF = Expected Double Recombinant Frequency

In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.

Explain a scenario in which secondary succession would occur.
andrey2020 [161]

Answer:

In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.
