DNA is ultimately responsible for the proteins that are produced in an organism. What is the process (name and describe it) that produces proteins, and what are the roles of chromosomes, DNA, and genes in this process?

Answers

Answer 1

Answer: Protein Synthesis:
Consists of transcription within the nucleus, then translation outside of the nucleus (can occur on the rough ER or in the cytoplasm using ribosomes). The DNA (unwound chromosomes) contain genes that code for specific proteins using the four different nitrogenous bases, A T C G. In transcription, RNA polymerase (a protein) binds to a specific gene sequence on DNA. The binding is caused by signals within the cells or outside the cell that basically say "we need more of this right now" (a good example is lactase which tells the cell it needs to make proteins that digest lactose in the presence of lactase, an enzyme). It runs alonga segment of DNA and makes an RNA copy, called mRNA (messenger). The messenger RNA is the spliced and "introns", extra bits of coding on the mRNA, are removed. the mRNA then moves outside the nucleus into the rough ER (or it could work in the cytoplasm using free ribosomes), where it binds to two ribosome subunits (one is called large, and the other is small. you can guess why). The mRNA then goes through Translation, where another type of RNA called tRNA (transfer) reads the mRNA 3 letters at a time, and attaches the appropriate amino acid to a chain. A triplet of letters each code for a different amino acid, and a chain of amino acids makes a protein.
The whole process is only a bit more complicated, with names of certain parts of the RNA, but this is the basic jist of it.
tl;dr... chromosomes unwind during interphase, DNA has genes that code for a chain of amino acids which creates a protein. Two main processes: transcription in the nucleus where the DNA sequence is copied to mRNA, then translation outside of the nucleus where the mRNA is read in a ribosome and an amino acid chain is assembled

A baseball rolls across the grass until it eventually comes to a stop. What happens to the ball’s kinetic energy?

Answers

the balls kinetic energy will stop because it is no longer in motion which is what kinetic energy basically is

Answer: it changes to thermal energy.

Explanation:

How would the amount of available energy differ in the trophic level of the mouse compared to the trophic level of the hawk?a. Available energy would increase from the mouse to the hawk.
b. Available energy would decrease from the mouse to the hawk.
c. Available energy would initially increase from the mouse to the hawk, and then decrease over time.
d. Available energy would remain the same from the mouse to the hawk.

Answers

The answer would be B. The available energy would decrease from the mouse to the hawk. As the trophic level goes up the energy decreases because some of the energy is lost in the form of heat for every energy transfer. This energy being lost cannot be used by the organisms on the next level.

Answer:

b. Available energy would decrease from the mouse to the hawk.

Answers

The clinical microbiologist is setting up a minimum inhibitory concentration (MIC) test.

In this test, the microbiologist makes serial dilutions of various antimicrobial drugs in broth and then incubates each drug dilution with a standard amount of the patient's isolated pathogen. The MIC test helps determine the lowest concentration of an antimicrobial drug that can inhibit the growth of the pathogen. This information is crucial for determining the most effective treatment for the patient
The clinical microbiologist is setting up a Minimum Inhibitory Concentration (MIC) test. This test involves creating serial dilutions of various antimicrobial drugs and incubating them with a patient's isolated pathogen. The MIC test helps determine the lowest concentration of an antimicrobial drug that can inhibit the growth of the pathogen. This information assists healthcare professionals in selecting the most effective treatment for the patient.

Which of the following checkpoints determines if DNA replication was successful? a. G2
b. G1
c. M

Answers

Checkpoints that determines if DNA replication was successful is a. G2. There are two checkpoints in the cell cycle. The G1 checkpoint is right before the S phase and if something is wrong, phase will not occur. The G2 checkpoint is right before the M phase (mitosis). It is DNA damage checkpoint and it determines if DNA replication was successful.
