These are the correct answers to the following questions:
<span>1. Barney and Betty are about to have their first child. They both have "normal" feet but Barney's father has flat feet and Betty has a child from a previous marriage who has flat feet, meaning they are both heterozygous for the trait. What is the probability that they will have a boy with flat feet(recessive trait)?
A.25%
B.50%
C.100%
D.75%
2. humans, the ability to roll the tongue is a dominant trait. The inability to roll the tongue is a recessive trait. If two individuals homozygous recessive for this trait have a child, what is the chance that the child will be able to roll his tongue?
A.100%
B.0%
C.50%
D.25%</span>
Explanation:
DNA polymerase replicates the DNA supplied to all new cells produced while RNA polymerase drives DNA copy RNA synthesis. Unless corrected, error in DNA replication could result in the transmission of the error DNA to all next-generation cells.
Protein synthesis error will cause faulty copies of RNA and degraded proteins. To order to ensure the transfer of key genetic information to future generations of cells, failure to DNA replication must be corrected.
Heritability is a measure that is used to estimate the variation of phenotypic traits (observable traits) in a given population due to the variation or changes in the genetic make up (genotype) among certain individuals. some of these traits includes color blindness, tongue rolling and curly hair among others. However, some traits such as nearsightedness are caused or influenced by the changes in the environment and therefore Heritability is not a factor to consider when dealing with such traits.
messenger RNA (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus to the cytoplasm where it attaches to a ribosome.
transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.
