Answer #1

The genetic code is not overlapping. That means adjacent codons do not share nucleotides. Hence statement, genetic code is overlapping is the wrong statement.

Cytosine and guinine have three hydrogen bonds in contrast to adenine and thymine which have two hydrogen bonds. Hence GC pair is stronger compared to AT pair. Hence correct option is three hydrogen bonds.

The amino acid sequence in a polypeptide is known as primary structure of the protein. Hence correct option is primary structure.

One gene can have multiple effects is true statement. This effect is known as pleiotrophy. This effect is seen when there is a mutation in a single gene which affects multiple traits.

Note: As per Chegg guidelines we are supposed to answer first four questions. Hence please re-post rest questions in a set of four questions. We would be happy to help you. Thank you.
