Hey guys, could you help me with some of these questions please! 1. If a protein coding portion of a processed piece of RNA is 450 bases long with a stop codon at the end, how many amino acids will be formed in its corresponding polypeptide?

2. A hypothetical mRNA sequence has 27 codons, with a start codon at the beginning and a stop codon occupying the 13th codon and 27th codon.

3. How may proteins will be translated from this mRNA sequence and how many amino acids will they contain?

4. What will be the 1st amino acid of the translated proteins?

5. How many nucleotides are in the original mRNA sequence?

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
