Answer:
1. rRNA helps form ribosomes. mRNA provides the instructions for proteins to the ribosome. tRNA transfers amino acids to the ribosome, which are needed to create the protein.
2. The Central Dogma of Biology states that DNA holds the instructions for protein creation. These directions are copied by RNA, which the RNA then utilizes to create protein. (Also known as DNA to RNA to protein.)
3. Proteins are made in the ribosomes, which are small organelles inside a cell.
4. They are both nucleic acids. Both of them store genetic information. They also share the same basic components: sugar, phosphate backbones, and nitrogenous bases.
5.
a. RNA is single stranded; DNA is double stranded.
b. RNA contains uracil as a base instead of thymine.
c. RNA has ribose, while DNA has deoxyribose instead (hence the differences in their name: RNA means ribonucleic acid. DNA means deoxyribonucleic acid).
6. mRNA (messenger RNA), rRNA (ribosomal RNA), tRNA (transfer RNA)
Explanation:
1. AUG GAC CUA UAG
4. codons in mRNA .... and Triplets in DNA
Answer: In respiration, glucose is broken down to produce energy that can be used by the cell, a reaction that uses O 2 and produces CO 2 as a byproduct.
Explanation:
Given what we know, we can confirm that the couple in question has a 50% chance that their next child will be a girl.
<h3>Why are the odds 1/2 ?</h3>
This has to do with the fact that each child that the couple has is an independent event. While it is true that it is unlikely for the same event to occur many times in succession, the previous events do not influence the outcome of the next child.
Therefore, given that a child can be either male or female when born, the couple in question has a perfect 50% chance for their next child to be a girl.
