andre [41]

Explanation:

Mutations increase variation within a population.

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.

Further Explanation:

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

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.

Name the three hormones and how they affect the body
yaroslaw [1]

ACTH (Adrenocorticotrophic hormone) stimulates the adrenal glands to secrete its hormones.

hGH (Human growth hormone) also known as somatotrophic hormone is responsible for the growth of long bones, muscles and viscera.

TSH (Thyroid stimulating hormone) influences the structure of the thyroid and causes it to secrete thyroid hormone.

nadya68 [22]

Answer: function in the synthesis of proteins

Explanation:

Ribonucleic acid or RNA is a kind of essential nucleic acid present in the cells of the living beings. The main function of the RNA is to carry the information present in the coded form in amino acid sequence obtain from the genes to produce protein molecules. The amino acid sequence gets assembled on the ribosome brought about by the messenger RNA (mRNA) each amino acid sequence encodes for a typical protein molecule. A single strand of DNA acts as a blueprint for the synthesis of mRNA which is transcribed from the strand of DNA.
