Does DNA in prokaryotes and eukaryotes use the same nitrogenous base pairs?
Answer:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus.
Explanation:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus. Prokaryotic DNA is doublestranded and circular. ... The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
No, DNA in prokaryotes and eukaryotes does not use the same nitrogenous base pairs.
What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
Therefore, in all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

The bud shown in the diagram below was produced by asexual reproduction. Which process is responsible for the formation of the bud?
2 Asexual reproduction differs from sexual reproduction in that, in asexual reproduction..
(a) new organisms are usually genetically identical to the parent
(b) the reproductive cycle involves the production of games
(c) nuclei of sex cells fuse to form a zygote
(d) offspring show much genetic variation
Answer: 1. Mitosis
2. Answer A.
Explanation:
Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.
What is role of asexual reproduction in evolution?Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.
Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.
Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.
Therefore, new organisms are usually genetically identical to the parent.

How does DNA replication in prokaryotes differ from replication in eukaryotes?
Prokaryotic chromosomes have telomeres, and eukaryotic chromosomes do not.
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.
The prokaryotic DNA had multiple parts to be replicated, compared to one long chromosome in eukaryotes.
The rate of elongation during replication is slower in prokaryotes than in eukaryotes.
Answer:
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.
Explanation:
If eukaryotic chromosomes did not have many origins of replications then replication would take insanely long due to how much longer eukaryotic genes are!

Which blood cell is most abundant?
Which experiment could the scientists use that would best determine if these tiny structures are spores?
Answer:
The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.
Explanation:
Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.
Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:
1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.
2. Culture-independent methods: These methods are based on
the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.

Why are chromosomes so important that they must be precisely and correctly duplicated, sorted, and distributed when one cell divides into two daughter cells?
Answer: It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.
Explanation:
In mitosis a cell divides to form two identical daughter cells.

How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.
