Protein synthesis is important because it creates new proteins for the cell. Proteins are important because they catalyze chemical reactions, create structures, and allow for cellular communication.Answer and Explanation: DNA controls protein synthesis by storing the genetic code for all proteins. The ...
How is DNA packaged in the nucleus of somatic cells? How does DNA code for proteins in a cell? What is the DNA structure of eukaryotic cells? How does the structure of DNA allow cells to replicate? How can DNA be extracted from a plant cell?
通过描述 DNA 序列,科学家们可以确定个体之间的重要差异。 These unique differences have become the basis for what is known from our DNA fingerprint. 这些独特的差异已经成为我们从 DNA 指纹中了解到的基础。 The first ever recorded DNA fingerprint was made in 1984 by my friend Alec Jeffreys at the ...
Anytime we can pop into the kitchen for cool kitchen science experiments, I am all for it. Have you ever seen DNA up close? My guess is no! Well, extracting DNA from strawberries is not as difficult as you might think! Smashed strawberries, DNA you can see, and an AMAZING new ...
The genus Enterovirus (EV) of the family Picornaviridae includes poliovirus, coxsackieviruses, echoviruses, numbered enteroviruses and rhinoviruses. These diverse viruses cause a variety of diseases, including non-specific febrile illness, hand-foot-and-
Prokaryotic and eukaryotic chromosomal DNA is organized in different ways. Due to the circular nature of most prokaryotic chromosomes, they are often highly supercoiled under normal growth conditions. In contrast, eukaryotic chromosomes are linear and packaged using histone proteins, which are not ...
For example, one called Cas12a produces staggered cuts in DNA, in which one strand is longer than the other at each end. DNA sequences can then be paired with the overhanging strand. Cas14 makes cuts in RNA, instead of DNA, and could be useful for temporarily altering what proteins a ...
When you're pushing into the unknown, there's no guarantee of success, and so-called failure is your constant companion. 翻译: 我的博士导师范塔梅伦(E.E. van Tamelen)是他这一代中最具创造力的化学家之一,他所想的...
How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin? A portion of one strand of DNA has the sequence 5' AATGGCTTA 3'. If this strand is used as a template for DNA replication, what is the sequence of the newly ...
Explain how DNA will be paired with mRNA and make the protein by genetic code. EXAMPLE: TACGCAACACGAGATTTAGGTTGGTAGTGGCAC Why is DNA better than RNA as genetic material? Explain. Explain the differences between DNA and RNA. How are DNA, RNA, and proteins related i...
