DNA<span> is a double stranded molecule. The nucleotides on each </span>strand<span> are held to the opposite </span>strand<span> with hydrogen bonds. So if on one </span>strand<span> you adenine the </span>complementary<span> nucleotide is thymine. For guanine the </span>complementary<span> nucleotide is cytosine.</span>
Answer:
2
Explanation: GPCRs are a large family of cell surface receptors that respond to a variety of external signals. Binding of a signaling molecule to a GPCR results in G protein activation, which in turn triggers the production of any number of second messengers.
Answer:
a. Elongation rate of the core polymerase
Explanation:
The chemical added to the E. coli made it stop it's full length production of mRNAs but instead short nucleotide transcript because the chemical targeted the elongation rate of the polymerase enzyme.
A mitotic cdk-cyclin complex triggers entry into mitosis.
<span>
Cdk-cyclin complex consists of two units: cdk which is a cyclin-dependent kinase (catalytic subunit) and cyclin (regulatory subunit). This complex play a crucial role in cell cycle progression. There are different types of cdk-cyclin complex, for example, Cdk1-cyclin B1 complex triggers entry into mitosis (progresses the cell cycle through G2/M mitotic phase).</span>
