what is cyclin dependent kinase?​

Answers

Answer:

please mark as brainliest answer as it will also give you 3 points

Explanation:

Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.[1] They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene.[1][2] CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain.[1] By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27. CDKs phosphorylate their substrates on serines and threonines, so they are serine-threonine kinases.[1] The consensus sequence for the phosphorylation site in the amino acid sequence of a CDK substrate is [S/T*]PX[K/R], where S/T* is the phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine.[1]

Marco is given an immortal cell line of epithelial cells to dilute. The initial concentration is 12.5 million cells. If he does four 1:10 serial dilutions, what will be the concentration of the last serial dilution

Answers

Answer: 12.5 x 10^6/10000 = 1250 cells.

Explanation:

A serial dilution is the step-by-step reduction of the concentration of a solution. Usually, the dilution factor at each step is constant, resulting in a geometric progression of the concentration, which is logarithmic. Serial dilutions are used to create very dilute solutions by accurately reducing the concentration of a substance.

It is usually carried out in experiments where highly dilute solutions are needed, for example, those involving logarithmic scale concentration curves or those used to determine the density of bacteria. To do this, prepare several test tubes with, for example, 9 ml of dilution liquid and first add 1ml of the undiluted sample to the first tube and then make serial dilutions in the following tubes. The first tube will contain a 1:10 dilution, the second 1:100, the third 1:1000, the fourth 1:10000 and so on.

Use 1 ml of undiluted (stock) solution with a pipette into the first test tube, containing 9 ml of a liquid, which can be for example water, Phosphate-buffered saline (PBS) and mix. This is the 1:10 solution. For the second dilution, take 1 ml of the dilution from the 1:10 tube and add it to the 9 ml of liquid to make the  1:100 tube and mix. The third tube is prepared with 1 ml of the 1:100 solution and 9 ml of liquid and this will be the 1:1000 dilution. The last one is prepared with 1 ml of 1:1000 and 9 ml of liquid and it will be 1:10000 (the fourth dilution).

So, if you start with 12.5 million cells and dilute four times with serial dilutions of 1:10 each, the final concentration will be four times lower:

12.5 x 10^6/10000 = 1250 cells.

Answers

Answer:

The correct answer is - C. Photoautotrophs.

Photoautotrophs are autotrophs or organisms that are able to obtain their food by using photosynthesis. Photosynthesis is the process in which sunlight trapped by the organism and converts to inorganic material such as CO2 and H2O to organic material which is glucose or sugar molecules.

In termite's guts, various types of diverse ways of getting their nutritional needs are found according to the microbes are Chemotrophs, Heterotrophs, parasites, and decomposers.

Which organism is an example of a producer?
moth
mushroom
rose bush
cheetah

Answers

Answer

Rose Bush

Explanation:

Rose bush is an example of a producer. Therefore, the correct statement is option C.

What are producers?

Producers are organisms that produce their own food through photosynthesis and form the base of the food chain by providing food for all other organisms in the ecosystem. For example, plants, algae, and some bacteria are few examples of producers.

The rose bush is a producer belonging to the kingdom Plantae and can produce its own food through photosynthesis where it converts light energy into chemical energy. The rose bush also contains specialized structures called chloroplasts to carry out photosynthesis.

Moths and cheetahs cannot produce their own food. Moths, on the other hand, are insects belonging to the class Lepidoptera and feed on plants or other insects and mushrooms obtain their nutrients from dead organic matter and are decomposers which play an important role in breaking down organic matter in the ecosystem.

Therefore, rose bush is an example of a producer.

Describe the structure and function of the following organelles: nucleus, endoplasmic reticulum, Golgi body, mitochondria, lysosomes, ribosomes, and centrioles

Answers

Answer: A cell organelle is defined as a cellular structure which has a specific function. The structure and function of these organelles as explained below.

Explanation:

--> NUCLEUS: This is the largest and most important cell organelle. It is enclosed by a double- layered nuclear membrane with many pores. The structure of the Nucleus makes it the 'control center' of the cell. This, it contains genetic materials( chromosomes) which controls the Production of a new cell or the whole organism itself and it controls the type and quantity of proteins( enzymes) produced in the cytoplasm.

--> ENDOPLASMIC RETICULUM(ER): this is a system of membrane-lined sacs that form channels throughout the cytoplasm. It's membrane is continuous with the nuclear membrane. There are two types of endoplasmic reticulum: rough and smooth. The rough ER packs and transports proteins made by ribosome while the smooth ER is involved in lipid and steroid synthesis.

--> GOLGI BODY: This is a stack of membrane-lined sacs. It is continuously formed at one end and broken off as bubbles or vesicles at the other end. These vesicles carry 'export materials' like enzymes and hormones which the cell makes.

--> MITOCHONDRIA: This is a sausage-shaped body surrounded by a double-membrane layer. The inner membrane is folded to form partitions which project into the inside of the mitochondria. The energy producing reactions of cellular respiration take place in the mitochondria. It is thus often called the cell's 'power- house'.

LYSOSOMES: These are small round sacs that contains digestive enzymes which break down structures and substances. They are also involved in the transport of materials in and out of the cell.

RIBOSOME: These are found on the surface of rough endoplasmic reticulum and are sites for protein synthesis of the cell.

CENTRIOLE: Two rod-like centrioles are found at right angles to each other in an animal cell. They are found near the nucleus and seem to be concerned with cell division.

The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? Select one: a. Only the interaction between dominant genes. b. Only the interaction between recessive genes. c. The interaction between dominant and recessive genes does not determine inherited traits. d. The interaction between dominant and recessive genes.

Answers

Answer:

The correct answer is - D. The interaction between dominant and recessive genes.

Explanation:

The inheritance of genetic traits come from both parents and based of their gene it can be predicted what traits might found in the offspring. There two types of traits of a single gene, known as alleles. These alleles can be dominant which means they can mask the effect of another allele if present together. The allele that get masked by the dominant allele called the recessive allele. The interaction of both recessive and dominant alleles determines an inherited trait such as eye color.
