There are several types of changes that could happen. If one of the letters of DNA were to be changed to a differnt letter, this might result in a differnt amino acid being put into the protein being synthesized. Or, changing a single letter could tell the protein to stop being made (a stop codon is formed) this would make a much smaller version of the protein. If a letter is either inserted or deleted this is called a "frame shift" mutation and this totally destroyes the message. A sudden change in the sequence of DNA could also "silence" the gene turning off transcription so that no mRNA would even be made. Or, it could enhance transcription increasing the ammount of mRNA. There are many many ways that a DNA mutation can affect mRNA, do you need anything more specific?<span>Its very simple,mRNA is kinda messenger which takes information from genetic material(DNA) which will later get translated to functional protein.The information in genetic material is in the shape of sequence of nucleotides pairs.there are four kinda nucleotides 1.adenine,2.guanine3.cytosine4.thiamine.... nucleotides lare kinda codes which get imprinted on mRNA , where thiamine is exception coz it get transcribed to uracil.
,since mRNA does contain thiamine but it has a replacement known as uracil.So its very simple if there will be any change in nucleotide the information given to mRNA will also change .So u see sudden change in nucleotides will mean that information send to mRNA will get changed.other things getting affected would be protein.</span><span>.As mRNA will later translate this information to make proteins from amino acids</span>

belka [17]

Answer:By. skynesher / Getty Images. The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.Sep 29, 2019

Describe the biotic and abiotic features of the temperate deciduous forests
frez [133]
Living things in the environment such as plants, animals, and bacteria are biotic factors. Biotic factors also include once-living parts such as dead leaves on the forest floor. Abiotic factors are nonliving aspects of the environment such as sunlight, temperature and water. One important abiotic factor is soil.

How did adults slaves prepare children for the challenges of a life of slavery
Semenov [28]

Answer:

From the 16th to the 18th centuries, an estimated 12 million Africans crossed the Atlantic to the Americas in the trans-Atlantic slave trade. Used on plantations throughout the United States, Latin America and the Caribbean, enslaved Africans were shipped largely from West Africa. With an average life span of five to seven years, demand for slaves from Africa increasingly grew in the 18th century leading traders to take their supply from deep within the interior of the continent

Explanation:

Slave parents, in turn, sought to instill in their children a sense of loyalty to the slave community as a whole. They taught children to refer to other girls and boys as sister and brother
