A. amino acids B. nucleotides C. lipids D. carbohydrates 相关知识点: 试题来源: 解析 A。解析:“amino acids”氨基酸,是蛋白质的构建块。“nucleotides”核苷酸,是核酸的组成单位;“lipids”脂质,是一类有机化合物;“carbohydrates”碳水化合物,它们与蛋白质的构建块概念不同。反馈...
When our nucleotides are connected in a long chain like this, we refer to it as a nucleic acid — either DNA or RNA, but we’ll cover some differences on those shortly. Nucleic Acid Structure Now that we’re finally at nucleic acids, one important thing to note is how the nucleotides ...
nucleotides play central roles in metabolism. In that capacity, they serve as sources of chemical energy (adenosine triphosphate and guanosine triphosphate), participate in cellular signaling PEPTIDES: Peptides are short polymers formed from the linking, in a defined order, of α‐amino ...
c. Nucleotides. d. Amino acids. What makes an amino acid? How we can tell if an amino acid is hydrophobic or not? Which part, or what, do we need to look at to tell if this amino acid is hydrophobic? Which amino acid will be the most soluble in water? Explain why. A. Leucine...
Answer to: Nucleotides are large molecules made of DNA or RNA. True False By signing up, you'll get thousands of step-by-step solutions to your...
An in silico study of mRNA secondary structure has found a bias within the coding sequences of genes that favors "in-frame" pairing of nucleotides. This pairing of codons, each with its reverse-complement, partitions the 20 amino acids into three subsets. The genetic code can therefore be ...

TFIIH unwinds nucleotides surrounding the DNA lesion and further recruits the XPA (xeroderma pigmentosum complementation group A) protein and endonucleases (XPF/ERCC1 and XPG) to remove ~30-bp damage-containing nucleotides. Eventually, DNA polymerases and ligases fill and seal the residual gap to ...

The monomer of all nucleic acids, including DNA, are nucleotides. Nucleotides are composed of three independent parts: (1) a pentose sugar; (2) a... Learn more about this topic: Watson & Crick Model of DNA | Overview, Experiment & Base Pairing ...
