The pattern of transcription for a pair of identical twins (Tweedledee and Tweedledum) is very similar at the age of 10. However

by the time they are 50, transcription of the leptin gene is much higher in Tweedledee than in Tweedledum. This could be due to what change in Tweedledum? Group of answer choices

Answer:

Explanation:

My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.

B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.

Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.

Answer:

Our Genetic Code all use for example in You and I use ATGC and so would a Dogs DNA.

Explanation:

Thats the reason it looks similar we have the same building blocks. But when we arrange the letters in diffrent order is where our gentetic diversity comes from. The only slight diffrence is in RNA because it uses AU instead of AT

Fynjy0 [20]

The pipettes can basically be characterized into five grades. these grades includes the serological, disposable, repeat, single channel and multi-channel pipette. The guidelines for the usage of each of these pipettes differ. However, some instructions are common, such as the control of the flow of liquid. The index finger is used for the purpose of controlling the flow of the liquid from the pipette.

Hence, the answer is 'index finger'.
