The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.

trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.

Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.

PolarNik [594]

Answer:

Answer is Yeast infection.

Explanation:

Example of yeast infection found in that aspect is Candida yeast infection. This is because, Candida yeast infection thrive in moist warm area like under the breast.

The major symptom is the formation of itching rash.

The rash can be treated by the application of antifungal cream.

Which of these is NOT an interaction between a plant's root and shoot systems?
olga_2 [115]

Answer:

The stomata open to allow carbon dioxide to enter the leaves.

Explanation:

Higher plants are made up of two major system parts namely: shoot system and root system. The shoot system constitutes every part of the plant above the ground i.e leaves, fruits, stem etc. while the root system constitutes the part below ground i.e the roots. The shoot system and root system, however, interacts in several ways to ensure that the plant functions optimally. The ways they interact include:

- The roots (root system) absorb water from the soil, which is transported upwards to prevent leaves (shoot system) from drying up.

- The phloem, which is a conducting tissue, transports sugars (product of photosynthesis) from the leaves (shoot system) to the root nodules (root system) for storage.

- Nutrients are absorbed from the soil by the roots (root system) and moved to the stems (shoot system).

Note that, although it is true that "stomata in the leaves open to allow carbon dioxide to enter the leaves", there is no connection between the shoot and root system.

For each of the following features of nucleic acids, indicate whether it is true of DNA only, of RNA only, of both DNA and RNA,
suter [353]

Answer:

Nucleic acid is one of the four major macromolecules that is present in all life forms. It includes DNA ( deoxyribonucleic acid) and RNA (ribonucleic acid). It is made up of small unit called nucleotides.

A nucleotide contains a pentose sugar that is deoxyribose in DNA and ribose in RNA, nitrogenous base that is Adenine, Thymine, Cytosine, Guanine in DNA and Adenine, Uracil, Cytosine, Guanine in RNA, and a phosphate group.

It is synthesised by a process of comlementary base pairing ( such as in double stranded DNA, A pairs with T and G pairs with C).

DNA is converted to mRNA inside the nucleus of eukaryotic cell and mRNA is then translated to protein when it moves the cytosplasm of the cell.

Thus, the correct answers are as follows-

1) Is an inherently directional molecule, with an N-Terminus on one end and a C-Terminus on the other end - true neither for RNA or DNA.

2) Contains the base adenine- True for both DNA and RNA.

3) Contains the nucleotide deoxythmidine monophosphate- True for DNA

4) Occurs only in signle stranded form- True for both RNA and DNA( such as single stranded DNA in DNA virus, and RNA in single stranded RNA in AIDS virus).

5) Is synthesized by a process that involves base pairing- True for both DNA and RNA.

6) Is involved in the process of protein synthesis in the cytoplasm of the cells in the liver- True for RNA ( particularly messenger RNA, mRNA)
