Which method of finding exoplanets involves directly viewing the planet through various types of telescopes?​

Biology

musickatia [10]3 years ago

Answer:A star with a planet will move in its own small orbit in response to the planet's gravity. This leads to variations in the speed with which the star moves toward or away from Earth, i.e. the variations are in the radial velocity of the star with respect to Earth. The radial velocity can be deduced from the displacement in the parent star's spectral lines due to the Doppler effect

Ribosomal RNA is produced by _____.
lara [203]
Ribosomal RNA is produced by nucleolus<span>. Ribosomal RNA associates with a set of proteins to form ribosomes. They physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. Additionally, they bind tRNAs and various accessory molecules necessary for protein synthesis. Nucleolus is the structure within the nucleus that is responsible for the formation of these complex structures. The DNA is transcribed into ribosomal RNA precursor molecule which is later processed into mature rRNA. </span>

Name the site of production and release of oestrogen
Mademuasel [1]

Answer:

The pituitary gland produces FSH which causes the development of a follicle in the ovary. As the egg develops inside the follicle, the follicle produces the hormone oestrogen. The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH.

Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during t
balandron [24]

Answer:

DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments

Explanation:

Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
