there are a number of differences between viruses and bacteria.Bacterium,the singular form of the word bacteria,is a one-celled(单细胞) living thing,with complete sets of both RNA and DNA genetic codes( 遗传密码).For viruses,some are sections of RNA,and the others are sections of DNA.So...
Once bound, RNA polymerase begins the process of transcription, unwinding the DNA and synthesizing an RNA molecule that is complementary to the DNA template strand. Therefore, RNA polymerase is the enzyme that binds to DNA during initiation. Rate this question: 3. The region of DNA which ...
根据第 2 大段 “When the time is right, bacterium will divide its DNA and RNA genetic material in two.” 当时机成熟时,细菌会将其 DNA 和 RNA 遗传物质一分为二。可知,细菌会繁衍遗传物质。故答案填 genetic material 。 【 5 】 细节理解题。根据第 4 大段 “But most viruses, on the other...
Introns & Exons | RNA Splicing & Processing from Chapter 9 / Lesson 5 218K Learn about the process of RNA splicing and processing in the cell, as well as the differences between introns and exons and their role in the process. Related...
It also supports brain function as well as important for the RNA and DNA production. Niacin Content Flours having more gluten also have more niacin. This would aid in the production of hormones that are related to stress and sex and it also helps the body in terms of processing and using ...
The central dogma of biology refers to the following sequence: From DNA to RNA to Protein. This means that DNA encodes a specific sequence that translates into protein and mRNA used as the mediator between DNA and the protein.Answer and Explanation: ...
One main difference between viruses and bacteria is the method of reproduction. A bacterium is a completely independent and self-reproducing unit. When the time is right, bacterium will divide its DNA and RNA genetic material in two. This is how bacteria live in almost every environment on Eart...
This up and coming agritech trend is, in a nutshell, the process leading to genetically engineered products. This is achieved through advanced tools which allow the DNA and RNA of animals and plants to be efficiently edited. In particular, this provides a promising solution for pests and crop ...

Some changes involve only a single rung in DNA's twisted ladder, but others are more complex. So-called Alu elements are repetitive DNA sequences that can generate bits of RNA, a molecular cousin of DNA, that can convert back to DNA and then insert themselves randomly into the genome. ...
