The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
Pelvic inflammatory diseases (PID)
<span>Pelvic inflammatory
diseases (PID) is an diseases that affect 10-40% of women who had an infection
of either gonorrhea or chlamydia and it usually occur when the initial
infection such as chlamydia or gonorrhea
travels upward with other bacterias beyond the the cervix into the uterus,ovaries,
oviducts and pelvic cavity. However, PID is major cause of infertility in young
women.</span>
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
Due to the definition of the central dogma, another way of putting it is that the central dogma follows the flow of information from DNA to protein.
Answer:
b. the 20 amino acids found in proteins differ in the composition of their R groups, which may be either polar or charged.
Explanation:
Since the proteins are polymers joined by a big number of amino acids, all the joins occur the same way because in all the amino acids there is always one part that is exactly the same in all of them.
The rest of the molecule in the amino acids, the R group, is different in each one, that is the characteristic of each one, and this is the part that can give the name and some other chemical properties.
