Answer:

Option D.

All of the above.

Explanation:

This is because valine, leucine and serine have more than one codons. Leucine and serine have six codons each while valine have four codons.

Codon refer to a sequence of either DNA or RNA that is associated with a specific amino acid and can stop signal during protein production. The complete set of codons is genetic code.

Why is RNA polymerase a good name for the enzyme that carries out transcription

KATRIN_1 [288]

Answer:

RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.

Explanation:

RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .

one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.

RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.

Which of the following statements about the functional consequences of single base-pair mutations are TRUE? Select the three cor

Alchen [17]

Answer:

these statements are true

B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence

D) Missense mutations always change the amino acid sequence encoded by a gene

E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.

Explanation:

B) insertion or deletion of nucleotide in coding region of DNA can change the amino acid sequence encoded.

D) missense mutation means that the change in nucleotide sequence resulting in change in amino acid sequence encoded by gene.

E) A mutation may alter the promoter of a gene, thereby affecting the rate of transcription.

Tiles

1. construct a hypothesis

2. communicate the results

3. test the hypothesis

4. make observations

5. analyze the results and

make a conclusion

6. ask questions

Pairs

A. Bread, when kept in the open for a

long time, shows the presence of mold.

B. What causes mold growth on bread?

C. Changes in temperature may affect

the growth of mold on bread.

D. Keep the bread in different locations,

changing the temperature at each location.

E. Increased temperature leads to the

growth of mold.

F. Make a presentation of the data, and

explain it to the class.

Explanation:

<h3>ANSWERS :</h3>

1- C ( this is an assumption; a hypothesis is always based on an assumption.

2- F ( this states to share the results with other classmates).

3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.

4- A (this is something you could observe during the experiment, therefore it is an observation).

5- E (this sentence is a conclusion).

6- B (This is an actual question)
