What amino acids do the following ribonucleotide codons code for? (a) AAU (b) GAG (c) UCC (d) CAU (e) ACC What is the length of a helical protein consisting of 500 amino acids? What are cofactors and coenzymes? What proteins are synthesized mostly on free ribosomes?
Answer to: In genetic code, what does it mean "to code for"? (For example codons code for an amino acid, DNA and RNA code for proteins,)? By...
However, we’ll only see paternal haplotypes in folks with a Y chromosome (i.e., most males). The Y chromosome is the shortest chromosome. Though it has few genes — including the crucialSRYgene (aka testis-determining factor or TDF) — these genes are important. They code for things th...
A frameshift mutation will in generalcause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. What is frameshift mutation How does it affect functio...
codon partners, forming a new chain of amino acids with the sequence MWWM or AUG UGG UGG AUG. With the help of some extra molecules and enzymes, the tRNA codons detach from the amino acids and we have our string of MWWM — the very protein sequence that our model gene coded for!
How do exons convey which of 20 amino acids needs to be picked to build a protein? A set of three contiguous nucleotides in an exon acts as a molecular tag known as acodon. A single codon corresponds to one amino acid. Moreover,multiple codons can correspond to the same amino acid. F...
AUG methionine initiating codons are indicated, three inframe AUG codons are present in the uORF preceding the UCP2 coding sequence, so the AUG codon initiating UCP2 translation is the fourth. (B) Translation of UCP2 is impaired by uORF, and ribosomal subunits start scanning the mRNA at its...
codons available (43= 64). That is, starting with AAA, AAC, AAG, AAU and working all the way to UUU, there are 64 combinations. Humans, however, make use of only 20 amino acids. As a result, the triplet code is said to be redundant: In most cases, multiple triplets code for the...
the rRNA function includes a large ribosomal subunit joins the newly formed complex then both ribosomal subunits travel along the messenger RNA molecule as they translate the codons in the entire polypeptide chain as they pass over them. Ribosomal RNA creates the peptide bonds between amino acids in...
What links codons and anti-codons together during DNA translation? a) Briefly describe the function of the start codon. b) Briefly describe the function of the stop codon. c) Consider the genetic code. Notice that each amino acid can be encoded for by more than one codon. Why do you thi...
