Answer:
3' TACCGCAAA 5'
Explanation:
Transcription is the process by which a particular DNA sequence (e.g., a gene) is used as a template to synthesize a complementary RNA sequence that grows in a 5′ → 3′ direction. This RNA molecule is usually a messenger RNA (mRNA) which is then used to synthesize a polypeptide chain (i.e., a protein) by a process called translation. The complementary RNA molecule produced during transcription is synthesized according to the base pair rules, i.e., Adenine (A) bases always pair with Thymine (T) bases, while Guanine (G) bases always pairs with Cytosine (C) bases. In RNA, Uracil (U) bases pair with adenine, thereby replacing thymines during transcription.
The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.
The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes
Answer:
the male reproductive cell is called a(n) sperm
the female reproductive cell is called a(n) egg
when the male and female cells join during fertilization, a(n) embryo forms
Explanation
During a males life, the sperm forms. During a females life, the egg forms. When a man and a woman fall in love, the reproduce, causing the sperm and egg join to form a embryo
