Biology

lozanna [386]3 years ago

Answer:

No it would not be useful for cell.

Explanation:

RNA polymerase uses only one strand of DNA which is called the template strand for the synthesis of mRNA. The other strand which is not used to make mRNA is called the coding strand.

If an RNA polymerase is designed which transcribe both the strand than two different strands of mRNA will be generated that will have different nucleotide sequences and will code for different proteins. So one strands will generate a protein which have different amino acids sequence that will complicate the overall process for the cell.

Another problem is if two RNA strands are formed then they can form a double helix and the ribosome might not be able to bind on them and translation might stop. Therefore it would not be useful for cell.

How are the 3 stages of cell division similar to how new animals are created?
Vera_Pavlovna [14]

Answer:

Cell divison is defined as the process in which a parent cell split into two or more daughter cells. There are three stages of cell division that includes interphase, mitosis/meiosis and cytokinesis.

In the interphase the proteins, enzymes and cell organelles are formed and at the end of this phase single strand chromosome becomes a double strand carrying genes.

In the meiosis (in sexual reproduction) or mitosis (asexual reproduction) phase, divison of nucleus takes place. Meiosis gives rise to geneticaly different cells due to crossing over while mitosis leads to  identical cells .

Cytokinesis occurs cocurrently after meiosis or mitosis in which cytoplasm of a parental cell divides into two daughter cells each with identical chromatin.

Creation of new animals are also undergo these 3 stages of cell division that is interphase, meiosis (eukaryotes)/mitosis (prokaryotes) and cytokinesis. Majority of animals (eukaryotes) undergo meiosis phase because their mode of reproduction sexual and have genetic variation due to crossing over of chromosomes and produces 4 daughter cells at the end cell division.

Hence, the 3 stages of cell division is similar to craetion of new animals.

EASY QUESTION:<br> What are two suggestions you would make about ways to conserve water?
olganol [36]
Turn off the water when it is not needed; for example, turn off the water when you brush your teeth, turn off the water when you’re scrubbing your body and hair in the shower with soap (only turn it back on when you want to rinse).

To summarize: TURN OFF THE WATER (when it’s not needed) :)

Secretion of human chorionic gonadotropin (hcg) occurs during what time frame during pregnancy?
masha68 [24]
Secretion of human chorionic gonadotropin [HCG] only occur during pregnancy in the placenta. The concentration of this hormone increase rapidly during the first three months of pregnancy; the amount in the blood stream doubles every two to three days as the development of the placenta and embryo progress. The hormone reaches its maximum concentration peak around the sixth week of pregnancy and after this, its concentration decline.

A person working in your lab creates a synthetic semi-fluid like substance embedded with proteins that transport nutrients and i
morpeh [17]

It is mostly likely the cell membrane.

The cell membrane is a structure of a cell composed of double layer of lipids and proteins. It surrounds a cell and separates the cytoplasm from its surrounding environment. The cell membrane is selectively permeable (semi-permeable), which means that it only lets certain molecules enter and exit. It can also control the amount of some substances that go into or out of the cell.
