Any of the pairs of the hydrogen-bonded purine and pyrimidine bases that form the links between the sugar-phosphate backbones of nucleic acid molecules: the pairs are adenine and thymine in DNA, adenine and uracil in RNA, and guanine and cytosine in both DNA and RNA.
If there’s a capitol in both the answer will be both capitals if one has one capital and the other has two lower. Case then it will be one capitol and one lower case. If both have two lower case is lower case. Ex: mom: Rr dad : Rr the child will have RR bc it’s dominant. If mom Rr and dad rr then child will be Rr. And if both are rr so will the child
The sequence of bases on RNA that would match or pair with the following DNA sequence: GCA is CGU.
<h3>What is transcription?</h3>
Transcription is the process by which mRNA sequence is produced from a DNA template in the nucleus of a cell.
During transcription process, the following applies:
- Adenine (A) pairs with Uracil (U)
- Guanine (G) pairs with Cytosine (C)
This means that the mRNA sequence that will result from a template of DNA with sequence: GCA is CGU.

Helper T cells are found in the <u>Thymus.</u>
Explanation:
Immature T-cells are formed in the bone marrow, just like any other blood cells, through the process of hematopoiesis. These immature T cells are then transported to the thymus where they mature and differentiate into the different types of T cells; cytotoxic, helper and regulatory. T-helper cells, also called CD4⁺ cells, are important in activating B-cells and T-cytotoxic cells in case of infection.
<span> Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.</span>
