During the climacteric may be a transient burst of rna synthesis . 在轉(zhuǎn)換時期的RNA合成可能有短暫的驟增。
Messenger rna is templated along only one of the two strands of a dna molecule . DNA分子兩條中只有一條作為信使RNA的模板。
A third class of rna is also required for protein synthesis, the ribosomal rna . 蛋白質(zhì)合成還需要第三類RNA,即核糖體RNA。
Ribose and deoxyribose are constituents of the nucleic acids rna and dna . 核糖與脫氧核糖分別是核糖核酸與脫氧核酸(DNA)的結(jié)構(gòu)成分。
Specific mrna sequences can be enriched for by preparing the rna from subcellular fractions . 從亞細胞部分制備RNA,可使專一的mRNA序列的豐度提高。
Erythrocytes recently released by the bone marrow into the bloodstream often contain ribosomal rna . 剛從骨髓釋放入血流不久的紅細胞含有核蛋白體RNA。
Superpure dna can be prepared using rna transcribed from dna in the course of gene expression . 在基因表達期間,使用從DNA轉(zhuǎn)錄而來的RNA可制備出超純度的DNA
The monopartite genome of tobacco mosaic virus is a plus-strand rna molecule of 6395 nucleotides . 煙草花葉病毒的單份基因組是一個6395個核甙的()鏈RNA分子。
Molecular genetics came to depend upon studies of the structure and function of dna, rna and protein . 分子遺傳學(xué)的形成仰賴于DNA,RNA和蛋白質(zhì)的結(jié)構(gòu)與功能的研究成果。
Two major kinds of nucleic acids are found in living things: deoxyribonucleic acid or dna and ribonucleic acid or rna . 生物中存在著兩大類核酸:脫氧核糖酸和核糖核酸。
Ribonucleic acid (RNA) is a ubiquitous family of large biological molecules that perform multiple vital roles in the coding, decoding, regulation, and expression of genes. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for all known forms of life.
