#6: Fact

BIAS: Tomatoes taste better when fish

DNA is inserted into them. Cereal is more

filling when cow DNA is inserted into it.

Testing GMO on rats and cockroaches

is ethically wrong.

FACT: Genes from different species can

be spliced into an organism to produce

desired traits. GMO crops can be

designed to grow in environments where

the natural species can't grow. The genes

from GMO plants can spread to natural

species if they successfully mate.

Hope this helps! :)

6) If a mutation happens in a cancer-causing gene to change the subsequent protein's function,
Aneli [31]

Explanation:

B) False

Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer

Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.

Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

active transport occurs in cells for example when Na-k pump is at work.Any process that involves active transport most often inv
vekshin1

Answer:

Any process that involves active transport most often involves the​ expenditure of energy in the form of ATP hydrolysis.

Explanation:

Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.

Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.

In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.

The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates, which decorate both the proteins and lipids and help cells recognize each other. Hope this helps :)
