What is the function of the mRNA? RNA RNA is short for ribonucleic acid, which is a polymer that consists of nucleotides that have a 5 carbon sugar, a phosphate group and a nitrogenous base. RNA in all life tends to be single-stranded, and less stable than DNA counterparts. ...
DNA replication is the process by which a new DNA strand is synthesized from an old one in a semi-conservative fashion. In DNA replication, new bases are added to a new strand by the enzyme DNA polymerase.Answer and Explanation: The function of the RNA primer in DNA replication is to ...
Different messenger RNA are translated at different rates by the cell. Each mRNA differs in the rate at which they are translated into protein and in the stability of the mRNA molecule. The longer-lasting an mRNA molecule is, the more protein products that can be transcribed from the mRNA se...

What is the function of the hypothalamus?(1)对生物节律的控制。 (2)对体温的调节:下丘脑存在对体温变化敏感的神经元。 (3)对水平衡的调节:下丘脑有引水中枢和渗透压感受器。 (4)对摄食行为的调节:下丘脑有摄食中枢和饱觉中枢。 (5)对内分泌腺的调节。
信使RNA(mRNA)是一大类RNA分子,它将遗传信息从DNA传递到核糖体,在那里作为蛋白质合成模板并决定基因表达蛋白产物肽链的氨基酸序列。RNA聚合酶将初级转录物mRNA(称为前mRNA)转录成加工过的成熟mRNA,这种成熟的mRNA被翻译成蛋白质。 如在DNA中一样,mRNA遗传信息也保存在核苷酸序列中,其被排列成由每个三个碱基对组成的...

RNA is a critical component of every single living cell in the universe. Without it, life as we know it could not exist. There are three types of RNA, each with a unique function. mRNA is used to produce proteins from genes. rRNA, along with protein, for
(什么是原核生物多顺反子mRNA ? 解释它的生物学意义)相关知识点: 试题来源: 解析 答:(1)在RNA病毒和原核生物中,凡在一个mRNA分子上携有几种蛋白质分子的氨基酸序列信息的mRNA(mRNA上相邻的顺反子在相应的DNA上多数也是相邻的),则这一mRNA就称作为多顺反子mRNA。 (2)原核生物基因表达调控的一个重要方式是...
