If you made a change in the promoter sequence in the dna that inactivates the promoter, what would happen at the rna level? the

mutation of the dna would be carried through to the rna sequence. the dna helicase would not be able to recognize and bind the dna, so the rna would not be made. nothing, the rna would be made as usual. the rna polymerase would not be able to recognize and bind the dna, so no rna would be made.

Answer:

Scientists with different educational backgrounds can come to different interpretations of the same data.

Choice A is correct

Explanation:

A biologist is a scientist with specialized knowledge in the field of biology while a geologist is a scientist who studies the matter that make up the Earth as well as the processes that shape them.

Both scientists came to different interpretations of the same data since they have different educational backgrounds.

An individual with the genotype BBTt could produce the gametes
yaroslaw [1]

Answer: Option C

Explanation:

The homozygous pair produces single type of  gamete and heterozygous pair produces two different types of gametes.

Here, BBTt has B trait in homozygous condition and so only B allele will be passed as gamete to the next generation.

Since, Tt is in heterozygous condition then T allele will be passed on to half gamete and t will be passed on to half of the gamete.

So, the gametes will be BT and Bt only.

Hence, the correct answer is Option C.

The recombination frequency between three genes A, B, and C located on the same chromosome is obtained as follows:
vagabundo [1.1K]

Based on the given recombination frequency, Genes B and C are closest to each other. This is because they bear the recombination frequency of 10%.

<h3>What is Recombination frequency?</h3>

Recombination frequency may be defined as a proportion of recombinant offspring delivered in a genetic cross between two organisms. It is always expressed in percentages.

The complete question is: The recombination frequency between three genes A, B, and C located on the same chromosome is obtained as follows:

  • A and C - 28%
  • A and B - 18%
  • B and C- 10%

Based on the result, which two genes are closest to each other?

Hence, the answer to this question is, that Genes B and C are closest to each other. This is because they bear the recombination frequency of 10%.

A lower recombination frequency of 10% means that the genes are located at a distance of 10cM from each other in a chromosome. The short distance between the two genes allows fewer recombination to happen, thus the frequency is lower.

Therefore, it is well described above.
