What is genetic engineering?

Genetic engineering (also named genetic modification) exists as a system that operates laboratory-based technologies to change the DNA makeup of an organism. This may influence changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a unique element of DNA.

Genetic engineers change, splice, eliminate, and rearrange genes to change an organism or classes of organisms. Genetic engineering, also called genetic modification or genetic manipulation exists in the modification and manipulation of an organism's genes operating technology.

Genetic engineering stands performed in three fundamental steps. These exist,

(1) The isolation of DNA components from a donor organism.

(2) The insertion of an isolated donor DNA fragment into a vector genome.

(3) The effect of a recombinant vector in a suitable host.

Hence, The accurate order is,

I. Replicate the new organism.

II. Isolate the genes from the specialist cell.

III. Select the desired trait.

IV. Insert the genes into the target organism.

Thus, Option C is correct.

Single Strand Binding Proteins are responsible for:
A. keeping the strands separated during replication.
B. unwinding and separating the DNA strands.
C. adding the new bases.
D. linking the short sections of the lagging side.
Reset Selection

Answers

Answer:

A. keeping the strands separated during replication

Explanation:

Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.

After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.

The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?




The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

The kelp population would increase: sea otters eat urchins, but not exclusively.

The kelp population would remain unchanged; sea otters do not eat the kelp.

The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.

Answers

Answer:

The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Explanation:

The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.

Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.

Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

Name two organs that are made up of all four tissues?

Answers

i believe the heart and lungs are 2 organs made up of 2 or more tissues

Heart and lungs are the  two organs that are made up of all four tissues.     secretion, movement, strength, excretion and communication are the main functions of tissues.

What are tissues in human body?

Tissues are the same type of group of cells which have the same structure and functions together in a unit. Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue bone, blood, and lymph tissues.

All body surfaces are covered in epithelial tissues, which also line bodily cavities and hollow organs and make up the majority of glandular tissue. Connective tissues are presents in the blood cells in the human body. Loose connective tissue, adipose tissue, dense fibrous connective tissue, elastic connective tissue, cartilage, osseous tissue, and blood are further more tissues in the body.

Thus, Heart and lungs are the  two organs that are made up of all four tissues.

Answers

Answer:

1,6 m / s ^ 2

Explanation:

De las leyes de Newton;

Fuerza = masa × aceleración

masa = 275 kg

Fuerza = 440 N

Aceleración = Fuerza / masa

Aceleración = 440N / 275Kg

Aceleración = 1,6 m / s ^ 2

D. A form of virus that infects cells.​

Answers

Answer:

A. strands I'd DNA wrapped around proteins.

Explanation:

DNA is securely packed within the nucleus by chromosomes, which are thread-like structures. Histone proteins offer structural support for DNA by coiling it around them. During cell division, chromosomes assist in the replication and distribution of DNA. Each chromosome has a centromere, which separates the p (short) and q (long) arms. The centromere is found at the constriction point of the chromosome, which may or may not be the center.

Jim has become particularly interested in the genetic basis of cancer and has spent considerable time reading published papers about oncogenes. He learned that as early as 1972 researchers suggested that mutations in proto-oncogenes caused by carcinogens can convert them to oncogenes. He asked you to answer a couple of questions about this because he did not have the biology background to totally understand. Jim learned that some cancer cells produce more growth-stimulating proteins than others. What would you give him as a plausible explanation

Answers

Answer:

Proto-oncogenes may have mutated to become oncogenes in these cells

Explanation:

Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.
