A scientist found that a Petri dish from an experiment had not been cleaned several days earlier. In the dish, she discovered a bacterial culture that she had not seen during the experiment. How could she gather evidence to support a claim about whether the bacteria had developed from the material left from the earlier experiment? a)Take a sample of the bacteria and grow it in an incubator. b)Gather dirty Petri dishes from other labs to see if they grow the same bacteria. c)Check all the clean Petri dishes for residue from the previous experiment. D)Try the original experiment again, do not clean some of the Petri dishes, and see if the bacteria grow.

6 steps of translation in order biology

Answers

Answer:

step 1: mRNA attaches to the ribosome

step 2: tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids

step 3: tRNA carries its specific amino acid to the ribosome

step 4: tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA

step 5: Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond

step 6: Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain

Final answer:

Translation in biology involves converting the mRNA transcript, which comes from DNA, into a protein through six stages: Initiation, tRNA elongation, amino acid bonding, mRNA shift & release, arrival of the next tRNA, and termination with a 'stop' codon.

Explanation:

In biology, the process of translation converts the sequence of codons in mRNA, obtained from DNA transcription, into an amino acid chain or a protein. This process occurs in six primary steps:

  1. Initiation: The ribosome binds to the mRNA transcript.
  2. Elongation: tRNA anticodon recognizes the next mRNA codon in the sequence, allowing the tRNA to present its amino acid.
  3. Amino Acids Bonding: With the help of enzymes and energy, the growing polypeptide chain attaches to the amino acid presented by tRNA.
  4. Shift & Release: The tRNA molecule then lets go of the mRNA strand, and the mRNA strand shifts one codon over in the ribosome.
  5. Next tRNA Arrival: The next tRNA arrives with its matching anticodon.
  6. Termination: A 'stop' codon on the mRNA triggers termination, initiating the release of the new protein.

How does the amount of precipitation affect the amount of weathering?

Answers

Answer:

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.
