One strand of DNA nucleotides is read as 5' - GCATATTG - 3'. What would
be the complementary strand?

Answers

Answer:

The correct answer would be: 3' - CGTATAAC - 5'

Explanation:

DNA molecule is a double-stranded molecule structure that has two distinct nucleotide chains joined together with hydrogen bonds between the nitrogenous bases of each strand. Adenine binds with thymine and cytosine binds with guanine by hydrogen bonds always in complementary strands.

These strands are complementary to one another as they have complementary bases in the complementary strand of one nucleotide chain of DNA. So,

5' - GCATATTG - 3' - DNA nucleotide of one strand

3' - CGTATAAC - 5' complementary strand

-)))
A)
Mass increases at the crust.
B)
Less mass on the mountain causes uplift.
0
The crust beneath the mountain thins and rises.
D)
The mass of the crust decreases and the mass of the mantle increases.

Answers

Answer: It's A.

Explanation: I am doing UsatestPrep, Now I got this answer wrong, but afterwards it told me the right answer is! "Mass increases at the crust" I got the answer wrong originally because I chose B but it's actually A.

Answer:

Its A because Mass increases at the crust. . Mass is actually decreasing due to erosion of the crust, isostatic adjustment will thus, cause the mantle mass to increase over time.

Explain why lamarckism is currently not a widely accepted theory​

Answers

Answer:

Its not really taught in schools that much.

Explanation:

Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.

Lamarck’s theory of evolution, also called as theory of inheritance of acquired characters was rejected since he suggested that the acquired character which an organisms gain through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individual’s set of genes.

What are the two main types of cells and where are they found in the human body?

Answers

Answer:

They are prokaryotes and eukaryotes and prokaryotes are single celled and eukaryotes are multi celled

Explanation:

Hope that helps! Have a fantastic day!

The two types of cells found in the human body are blood cells and immune cells.

What are cells?

Cells are the fundamental foundations of all life. Trillions of cells make up the human body.

They support the body's structure, absorb nutrients from food, repurpose those nutrients into energy, and perform specialized functions.

Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic compounds found in all cells.

A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.

The cytoplasm contains complicated accommodations of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.

Thus, there can be many cells in a human body, the most important perhaps are blood cells and immune cells.

What is an exoskeleton?

An exoskeleton is an outer skeleton that is present outside the body of some insects and other organisms. The exoskeleton is made up of hard substances like calcium carbonate or chitin protein.

The exoskeleton protects the soft tissues and organs of organisms. They are helpful in saving the organism from predators and other factors of the environment.

The exoskeleton is present in most arthropods. They also help in reducing water loss from the body.

Predict the method that estrogen will initiate the reception process in its cell signaling pathway.

a. Estrogen will bind to a transmembrane signal receptor that activates cell-signaling pathways.
b. Estrogen will act as a steroid signal receptor that activates ion channel proteins.
c. Estrogen will serve as a second messenger that activates cell-signaling pathways.
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.

Answers

Answer:

d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.

Explanation:

Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.

Answers

Answer: create proteins by bonding together amino acids.

Explanation:

Translation can be defined as the process in which the messenger RNA is decoded in the ribosome that is outside the nucleus. This is done to produce the specific chain of amino acid to produce polypeptide chain. The polypeptide chain get folded to produce protein this protein is responsible for performing functions in the cell. The genetic code determines the relation in between the amino acid sequence and base pairs in the gene.
