Transcription is the process that must happen in order to make

Answers

Answer:

a protein

Explanation:

Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

Transcription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble.

What does it mean to be in the same species

Answers

Answer:

organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.

I need help with the last two questions pleaseit’s due today.

Answers

D) yes because in order to inherent a recessive trait you would have to have two recessive genes. In this case it’s (gg)
E)Yes because the parents have the genes (Hh) and (hh). (I’m assuming based off the first question) Therefore, if an offspring has hanging earlobes there’s a 50% chance they’d have the genes (Hh)

relate diffusion and equilibruim​

Answers

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

which of the following are key elements of darwin's theory of evolution by natural selection?

Answers

Answer:

Independent assortment and crossing over contribute to diversity within a population's gene pool. These processes occur during meiosis and result in the recombination of DNA.

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.

What Darwin's theory of evolution by natural selection?

Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.

Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.

Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.

Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

What is the significance of crossing over?

Answers

Answer and Explanation:

Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.

This all happens in Meiosis, which is the process of the formation of sperm and egg cells.

The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

#teamtrees #WAP (Water And Plant)

Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
