After an RNA molecule is transcribed from a eukaryotic gene, what is removed and what is spliced together to produce an mRNA molecule with a continuous coding sequence?a) operators; promoters. b) exons; introns. c) silencers; enhancers.d) introns; exons. e) promoters; operators.

Answers

Answer 1

Answer:

Answer:d)introns; exons

Explanation:Introns are the non-coding portion of the DNA. They do not code for a gene that can be expressed hence the need for them to be removed from the coding genes(Exons). The exons are then joined together after the introns have been removed to create a sequence of amino acids.

Heredity refers to the __________.a. removal of DNA from the human body
b. formation of chromosomes from DNA
c. many types of Aryan genes
d. passing of traits from parents to children

Answers

Hereditary refers to a passing of traits from parent to children. When you say heredited it means that something from their parents are passed to their children, may it be th physical appearance, emotional characteristics and in many more aspects.

Answer: The correct answer for the fill in the blank is D) Passing of traits from parents to children.

Heredity can be defined as the passing of traits from one generation to the next generation. These traits can be the mental or physical characteristics of the parent. The traits are passed to the offsprings in the form of genetic material, which is DNA ( deoxyribonucleic acid) in most of the life forms.

Example- The genes ( segment of DNA, which code for specific proteins) for green eyes are passed from parent to child. This gives green eye color to the child.

Thus, the correct answer is Heredity refers to the passing of traits from parents to children

If you feel pain during weight training, what should you do?Move more quicklyMove more slowlyIncrease weightStop altogether

Answers

If you feel pain, moving faster, adding more weight, or even moving slower could end up in feeling more pain. The best thing to do is just plainly to stop altogether and get some rest. Pain is supposed to tell you something is wrong with your body when you do a certain exercise.

Answer: Option (d) is the correct answer.

Explanation:

When we do weight training then our muscles start to work even harder as compared to the work that they normally do.

So, it is required to initially start weight training with less weight but if you feel the pain during weight lifting then it is advisable to stop altogether. This is because continuing the weight training might lead to serious muscle injury.

So, it is better to stop the training and continue only when the pain is relieved.

Thus, we can conclude that if you feel pain during weight training, then you should stop altogether.

Mitosis and meiosis are methods of cell division. Which of the following is true of these two methods? A. Meiosis involves only one division, while mitosis involves two divisions. B. Mitosis involves two or more divisions, while meiosis involves exactly two divisions. C. Meiosis involves two or more divisions, while mitosis involves exactly two divisions. D. Mitosis involves only one division, while meiosis involves two divisions.

Answers

Answer:

D. Mitosis involves only one division, while meiosis involves two divisions.

Explanation:

Mitosis and meiosis are processes of cell reproduction that happen in living beings. They originate cells for different purposes. Each mitosis produces two cells equal to the source. An meiosis creates four daughter cells with half the genetic material of the mother cell.

D. Mitosis involves only one division, while meiosis involves two divisions.

Mitosis --> Two identical diploid daughter cells from one division

Meiosis --> Four unique haploid daughter cells from two divisions
