A mutation in a promoter sequence most directly affects the binding of what to dna

Biology
1 answer:
Karo-lina-s [1.5K]3 years ago
6 0

Answer:

RNA polymerase

Explanation:

The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences  that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.

Which of the following macromolecules enter the nucleus of a eukaryotic cell through pores in the nuclear membrane? a. rRNAb. ri
Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

TRUE OR FALSE<br><br> Both animal and plant cells use cellular respiration to make energy.
Radda [10]

Answer:

It's responsible for cellular respiration in both plants and animal cells. The difference is that plants also have chloroplasts that perform photosynthesis. Animals get their energy by eating food, digesting it, and turning it into the base sugars, proteins, and lipids that the cells can burn to perform cellular respiration (which makes ATP).

Explanation:

Hope this helps!!!!

Mt-UcGAN: Multi-task uncertainty-constrained GAN for joint segmentation, quantification and uncertainty estimation of renal tumo
olga nikolaevna [1]

Multi-task uncertainty-constrained GAN(Mt-UcGAN) for joint segmentation, quantification and uncertainty estimation of renal tumors on CT conclude that the integrated segmentation, quantification, and uncertainty estimate of renal tumors were initially proposed using a multi-task uncertainty-constrained generative adversarial network (Mt-UcGAN).

A novel adversarial technique with uncertainty limitations was put forth by us. Results from the experiment show that Mt-UcGAN can help with clinical tumor assessments.

Additionally, it can give medical professionals feedback on the validity of the findings, enabling them to undertake further visual reviews and revisions of the findings to raise the diagnostic accuracy.

The three main procedures for clinical tumor disease diagnosis are segmentation of renal tumor, measurement of tumor indices (i.e., center point coordinates, diameter, circumference, and cross-sectional area), and segmentation uncertainty estimation.

These tasks have, however, only ever been researched separately until now. It is quite difficult to describe two distinct tasks as a single optimization framework since segmentation and quantification tasks have separate optimization types.

In this study, we present a unified framework for the joint segmentation, quantification, and uncertainty estimate of renal malignancies on CT (Mt-UcGAN: Multi-task uncertainty-constrained GAN ).
