Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
Answer:
The answers to the blank spaces are numbered as follows:
1. Function
2. Nucleus
3. Mitochondria
4. ATP
5. Chloroplast
6. Glucose
7. Ribosomes
Explanation:
This question is describing the organelles found in a cell. An organelle is a structure that performs a specific FUNCTION (1) in a cell. There are different kinds of organelles with each possessing its own peculiar function. Some of them are as follows:
- NUCLEUS, which is regarded as the brain of a cell because it directs or controls a cell's activities just like the brain of an organism does.
- MITOCHONDRIA is an organelle that produces the energy storing compound called ATP (adenosine triphosphate), hence, it is called power house of the cell.
- CHLOROPLAST is an organelle found in plant cells that functions in the conversion of light energy (from sun) into GLUCOSE (chemical energy) in a process called PHOTOSYNTHESIS.
- RIBOSOMES is an organelle found in both prokaryotic and eukaryotic cells that serves as the site of PROTEIN production in a cell.
Answer:
The answer is indirect immunofluorescence
Explanation:
Immunofluorescence is a technique used to detect antigens by colors in a scientific setting using antibodies.
The test that can be used to determine pathogens using microscopy and fluorescently tagged antibodies is "indirect immunofluorescence".
This is used to identify diseases that attack the autoimmune system.
I hope this answer helps.
DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
