1. Name the two processes that occur in meiosis that increase genetic variation

Answers

Answer 1

The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.

Explanation:

Answer:

Also called the "Return key," it is the keyboard key that is pressed to signal the computer to input the line of data or the command that has just been typed.

It Was the Return Key

The Enter key was originally the "Return key" on a typewriter, which caused the carriage to return to the beginning of the next line on the paper. In a word processing or text editing application, pressing Enter ends a paragraph. A character code for return/end-of-line, which is different in Windows than it is in the Mac, Linux or Unix, is inserted into the text at that point. See CR/LF.

Answer:

D.

Explanation:

Paleozoic is not one of the 3 major periods of the Mesozoic Era

Hope that helps!

From 252 to 201 million years ago was the Triassic Period. Between 201 and 145 million years ago is the Jurassic Period. Between 145 and 66 million years ago was the Cretaceous Period, hence option D is correct.

What is the Mesozoic Era?

54 million years of the Mesozoic Era, or 199.6 to 145.5 million years ago, are referred to as the Jurassic Period.

The Jurassic Period, so named after the Jura Mountains in France and Switzerland, where rocks from this era were first investigated, has gained widespread recognition.

The Cretaceous is the final part of the Mesozoic Era, lasting from 145.5 million years ago to 65.5 million years ago, and is characterized by the demise of the dinosaurs (except birds).

Therefore, the Paleozoic is not a period of the Mesozoic Era, hence option D is correct.

The DNA in a strain of E. coli contains 32 % adenine. What percentage of DNA is cytosine

Answers

Answer:

The DNA of E. coli contains 19,120 6-methyladenines and 12,045 5-methylcytosines in addition to the four regular bases and these are formed by the postreplicative action of three DNA methyltransferases. The majority of the methylated bases are formed by the Dam and Dcm methyltransferases encoded by the dam (DNA adenine methyltransferase) and dcm (DNA cytosine methyltransferase) genes. Although not essential, Dam methylation is important for strand discrimination during repair of replication errors, controlling the frequency of initiation of chromosome replication at oriC, and regulation of transcription initiation at promoters containing GATC sequences. In contrast, there is no known function for Dcm methylation although Dcm recognition sites constitute sequence motifs for Very Short Patch repair of T/G base mismatches. In certain bacteria (e.g., Vibrio cholerae, Caulobacter crescentus) adenine methylation is essential and in C. crescentus, it is important for temporal gene expression which, in turn, is required for coordinating chromosome initiation, replication and division. In practical terms, Dam and Dcm methylation can inhibit restriction enzyme cleavage; decrease transformation frequency in certain bacteria; decrease the stability of short direct repeats; are necessary for site-directed mutagenesis; and to probe eukaryotic structure and function.Explanation:

It seems like they would be making just that much more noise to torment us. But, I hated it for the first several weeks, but then all of a sudden, I started to enjoy it because we had no money, but between the covers of those books, I could go anyplace, I could be anybody, I could do anything. And, I began to learn how to use my imagination more because it doesn't really require a lot of imagination to watch television, but it does to read. You've got to take those letters and make them into words, and those words into sentences, and those sentences into concepts, and the more you do that, the more vivid your imagination becomes. And, I believe that's probably one of the reasons that you see that creative people tend to be readers, because they're exercising their mind.I was reading about people in laboratories, pouring chemicals from a beaker into a flask and watching the steam rise, and completing electrical circuits, and discovering galaxies, and looking at microcosms in the microscope, and I just acquired so much knowledge, and I had put myself into those settings and I saw myself differently than everybody else in my environment who just wanted to get out of school so they could get some cool clothes and a cool car. And, I was looking down the pike and seeing myself as a scientist or a physician or something of that nature, and that was one of the things that sort of carried me through much of the ridicule and some of the hardships that a person would have to go through coming from my environment and going to medical school.The thing that I am probably the most proud of is not all the medical accomplishments or honorary degrees or various boards and societies. I'm most proud of the 100,000-plus letters that I have from young people, throughout America and around the world, whose lives have been changed by reading one of my books, or seeing me on television, or an interview in a magazine, and recognizing that they have the ability to define their own lives. If that's the legacy that I leave, I'll be very happy.I was talking to a friend of mine, who was a cardiothoracic surgeon, who was the chief of the division, and I said, "You guys operate on the heart in babies, how do you keep them from exsanguinating" and he says, "Well, we put them in hypothermic arrest." I said, "Is there any reason thatif we were doing a set of Siamese twins that were joined at the headthat we couldn't put them into hypothermic arrest, at the appropriate time, when we're likely to lose a lot of blood?" and he said, "No." I said, "Wow, this is great." Then I said, "Why am I putting my time into this? I'm not going to see any Siamese twins." So I kind of forgot about it, and lo and behold, two months later, along came these doctors from Germany, presenting this case of Siamese twins. And, I was asked for my opinion, and I then began to explain the techniques that should be used, and how we would incorporate hypothermic arrest, and everybody said "Wow! That sounds like it might work." And, my colleagues and I, a few of us went over to Germany. We looked at the twins. We actually put in scalp expanders, and five months later we brought them over and did the operation, and lo and behold, it worked.Autobiography1.
