RNA is the single-stranded molecule that determines the sequence of amino acids to build up the polypeptides. Transcription and translation are the two processes through which the DNA will convert into the sequence of amino acids.

In the lab, the steps of processes are being focused on. The investigatory questions of the experiments include:

Thus, the investigatory question in a laboratory experiment generally starts with 'how' and 'what.'

Mitosis and meiosis are the two types of cell division, which result in the generation of daughter cells. Yeasts are capable of undergoing meiotic and mitotic division under favorable conditions.

The correct answer is:

Option B: Crossing over genes during meiosis increases diversity and the chance of survival of the next generation.

The significance of meiosis can be explained as:

Thus, meiosis is an important step in the genetic variation and survival of the organism.

Therefore, option B is correct.

Answer:

For example, delays in mitosis are often ascribed to 'activation' of the mitotic checkpoint, a descriptor that fails to recognize that the checkpoint by definition is active as the cell starts mitosis. Conversely, the completion of mitosis in the presence of misaligned chromosomes is often automatically interpreted to indicate a defective checkpoint, even though in the absence of critical testing alternative interpretations are equally likely. In this article, we define the critical characteristics of checkpoints and illustrate how confusion generated by the inconsistent use of terminology may impede progress by fostering claims that mean very different things to different researchers. We will illustrate our points with examples from the checkpoint that controls progression through mitosis

Answer:

The 11 positive protons cancel out the 11 negative electrons, and the overall charge of the atom is zero. So it neutral

Explanation:

I hope this helps!!

The nucleus of an atom has only protons and neutrons. Since the neutrons are neutral, the charge on the nucleus, in this case, would be +11.

The difference between the number of electrons and protons in an atom is defined as the charge on that particular atom. An atom has three sub-atomic components. These are electrons, protons and neutrons.

The electrons are negatively charged, the protons are positively charged and the neutrons are neutral.

Because the neutrons are neutral, the increase or decrease in the number of electrons or protons affects the charge on an atom. If the number of protons is higher, the atom will be positively charged. If the number of electrons is higher, the atom will be negatively charged.

The protons and neutrons are present in the nucleus of an atom and the electrons are present in atomic shells.

Therefore, in a nucleus with 11 protons, and 12 neutrons, the charge will be +11

Until recently, most neuroscientists thought we were born with all the neurons we were ever going to have. As children we might produce some new neurons to help build the pathways - called neural circuits - that act as information highways between different areas of the brain. But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brain’s communication system.

In 1962, scientist Joseph Altman challenged this belief when he saw evidence of neurogenesis (the birth of neurons) in a region of the adult rat brain called the hippocampus. He later reported that newborn neurons migrated from their birthplace in the hippocampus to other parts of the brain. In 1979, another scientist, Michael Kaplan, confirmed Altman’s findings in the rat brain, and in 1983 he found neural precursor cells in the forebrain of an adult monkey.

These discoveries about neurogenesis in the adult brain were surprising to other researchers who didn’t think they could be true in humans. But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season. This was the same time in which the birds had to learn new songs to attract females.

Why did these bird brains add neurons at such a critical time in learning? Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. These new neurons made learning possible. If birds made new neurons to help them remember and learn, Nottebohm thought the brains of mammals might too.

Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area.

For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.

Identical genes have the same genetic material and the same genes. So if they both have a disease it's likely that it's genetic.

Scientists plan to use copy number variants (CNVs) and identical twins to determine the genetic differences between them and the cause of genetic disease as CNVs are variations in the copies of a gene in an individual's genome.

Scientists use copy number variants (CNVs) to study the genetic diseases in twins and CNVs are variations in the copies of a gene in an individual's genome, but in identical twins, they have the same genetic makeup. By analyzing the CNVs in twins, scientists can identify the genes that may be involved in the disease and how they contribute to its development.

Hence, scientists plan to use copy number variants (CNVs) and identical twins to determine the genetic differences between them and the cause of genetic disease as CNVs are variations in the copies of a gene in an individual's genome.

The process that begins with the replication of DNA in the nucleus of a cell is cell division, which is present in option A, and in the cell division phase, the cell divides to form daughter cells.

Cell division is a process in which the cell first grows in the G1 phase of the cell cycle, then replicates DNA in the S phase, then enters the G2 phase, and finally enters the mitosis or cell division phase. The DNA replication starts in the S phase, and in this phase, the DNA divides to form two DNA strands, so that in the division phase, each daughter cell gets parental DNA.

Hence, the process that begins with the replication of DNA in the nucleus of a cell is cell division, which is present in option A, and in the cell division phase, the cell divides to form daughter cells.
